Ravens threaten Daisy!

Daisy’s Monday morning in Australia (Sunday in North America) started out as beautifully as it ended the evening before. She had gone to forage returning at 19:45 yesterday evening. It appears to be a growing pattern, leaving in the heat of the afternoon and returning right before dusk. This pretty much ensures that she will miss the sea eagles if they come.

While she was away yesterday, the Rainbow Lorikeets came to visit Daisy, full of energetic chatter but, at the same time, wondering where she was! They are so cute. They almost look like stuffed plushies someone has placed on Daisy’s nest tree.

Where’s MY Daisy?

It is going to be hot again today for Daisy. They are predicting temperatures of 34 climbing to 39 tomorrow. Our pour little duck needs a paddle pool up there with her!

Daisy decided not to leave this morning for a bathroom break or to forage. Instead, she stayed on the nest. The Sulphur-Crested Cockatoos can be heard around 7:15 but it is an Unkindness that rattles Daisy’s world at 8:04. A group of Ravens is called an Unkindness and they were certainly not nice to Daisy. In fact, they were downright threatening. They moved from the top of the tree down closer. It was impossible to get am image of them in the tree (see second image below) but their shadows could be seen and their noise was deafening. Daisy was so frightened.

Look at the image below. Notice that Daisy has spread her feathers out in a manner similar to when a raptor mantles its prey. Her tail is fanned out and the feathers on her back are raised. She is protecting her clutch of eggs from these predators. The Ravens try harder and harder to get Daisy off her nest of eggs so they can eat them!

Daisy flattens her feathers and her head against the nest.

The Unkindness bullied Daisy trying to get her off her nest for five minutes. It must have seemed like a life time. And then they were away!

Except for the heat, the rest of the day has been relatively uneventful. The birds and animals of the forest are trying to expend as little energy as they can and remain cool in the hot Australian heat.

Daisy gathers up leaves and methodically covers her clutch of eggs and flies off to forage at 13:04:44.

Notice how Daisy has moved leaves over on top of her down and tucked it in tight today. She might be worried about the Ravens coming back to try and find her nest. Or maybe she thinks the sea eagles might stop in to see if anyone is incubating the eggs.

Daisy flies from the nest.

Look at the image above. You can just see Daisy flying off. It got really hot on the nest today. The afternoon is the worst. Daisy left a little earlier than usual. Eggs are incubated at 37.5 degrees. It is possible that the heat from outside and the down stuffed around could keep the eggs toasty warm until later today. I wonder if Daisy will return around 17:00 or if she will wait til almost dusk.

Thank you for joining us and checking in on the little duck that built her nest inside the nest tree of the big sea eagles.

Incubation Day 13 or the hottest day in Sydney

Daisy has been on the nest quietly but alertly brooding her eggs. She took a very early morning break from 4:13:44 to 5:16:34. Possibly a bathroom break for a duck or a chance to grab a quick breakfast and cool off in the water before one of the hottest days on the nest. It is 14:06:40 and our cute little duck is panting quickly in order to regulate her temperature despite the fact that there is now shade on the nest.

There is finally shade on the nest but it is still very very hot for our favourite duck.

Someone asked me about the ducklings. Is it safe for them to hatch and jump from a nest in a tree 75 feet high? Yes, it is perfectly safe. The ducklings are not harmed because the down on their body absorbs the impact. In fact, I am told that they actually bounce. It is hard to imagine! Last year a pair of Canada Geese laid their eggs in an Osprey nest in Minnesota. The goslings were recorded leaping down to the ground to everyone’s amazement. Some geese are known to build their nests on cliffs 150 feet high to be away from predators. No harm has come to the goslings when they have left from those nests.

Here is a video of a Wood Duck whose nest was in a very high tree. It is only 1.33 minutes long. Have a look. This is what Daisy’s ducklings will do. She will leap down to the forest floor and they will jump! Enjoy.

Wood Ducks Leaping from a very high nest in a tree.

Of course, there are many fears for Daisy. Remember, she is effectively a single mother in an environment that is unusual. Her ducklings will hatch and immediately start peeping. This will draw attention to the nest. It is only twenty-four hours after hatch that they take their ‘leap of faith’ jumping off of the big nest on the Ironbark Tree. But first, before they can do that, they have to survive any predators and somehow make their way through all those twigs to the rim without getting their little paddles caught up in them. And then there are the predators on the ground. I have often wondered why WBSE Dad has not damaged any more eggs. Is he just dropping by to check, waiting for them to hatch? Him and Lady are well known for bringing in the Silver Gull chicks to the nest for their eaglets. And then there is Mr. Raven and all the Pied Currawongs and last, but never least, the foxes. I am told that they have been removed from the park. I hope so. That would be one less thing for Daisy to worry about. But for now, we will just simply rejoice in every hassle free day that Daisy has. We are now half way in the incubation period to hatch watch: February 6-10.

It is now late afternoon in the forest. The sun is back shining on Daisy’s head and the nest cup. It is so hot that there are no sounds of any birds. Everyone is trying to keep cool.

Daisy begins to tuck the down in around her nest along with pulling leaves closer to her nest. Then she sees a shadow of a bird cross the nest and she stops! She waits and listens. Five minutes later she resumes her preparations for concealing her nest and heading to the water to eat and cool off. She flies off the nest to the left, to the closest water source, at 15:11:10.

Daisy moves her quickly to tuck in the down and pull leaves towards the nest.

It was so hot yesterday and it is even hotter today. If Daisy follows her pattern of late, she will return to the nest between 19:45:00 and 20:00. And if the Sea Eagles are being typical, if they are coming in to check it will be around 17:00 and Daisy will be gone!

Oh, it is going to be hot for Daisy!

Oh, welcome to The Daisy Chronicles, a daily update on the life of the little Black Pacific Duck that has made a nest in a White Bellied Sea Eagle nest in the Sydney Olympic Forest. It is Day 13 of incubation. We could be half way to hatch!

Och, witamy w The Daisy Chronicles, codziennej aktualizacji życia małej kaczki Black Pacific, która założyła gniazdo w gnieździe bielika morskiego w lesie olimpijskim w Sydney. Jest 13 dzień inkubacji. Mogliśmy być w połowie drogi do wyklucia!

————————————————————————————-It is 7:44 on the nest in Sydney, Australia and Daisy knew what the weather was going to be today. She got up early, at 4:13:44 to go for a swim and some foraging. The weather news says it will be 36 in Sydney today and it will be hotter on the nest with the direct sunlight at times.

How many times have you checked the weather only to find out that the weather report was wrong? When I was a little girl staying with my grandmother, she would open the front door of her house and ‘sniff’. Then she would declare that it was going to rain. At the time, not knowing anything, I thought she was a witch! How silly was that? But how do birds know the approaching weather?

Some say that the hollow bones of a bird help them determine the barometric pressure and, thus, they are able to anticipate incoming weather. Others say that it is the pressure plates within their ears. Daisy is not a bird but a waterfowl and still she anticipates the changing in temperature, rain, etc. That is because she, also, has hollow bones. Recent research at The University of Western Ontario suggests that birds have an internal barometer. They can tell even the slightest change in barometric pressure and temperature. And, of course, they have these skills because knowing if they should forage or hunt immediately, if rain or snow are coming, are essential to their survival. Researchers at the University tested their ideas by lowering and raising the air pressure inside a specially built wind tunnel. If they lowered the air pressure, the birds would immediately start looking for food and prey. Low pressure means that a storm or rain and winds is approaching. They might even have to find a safe place to stay for hours or even days depending on the strength of the storm. Likewise, if the barometric pressure and temperature rise a bit, the birds will have a reasonable morning in the nest preening before heading out to hunt or forage. Today, Daisy leaves her nest early because she knows that it is going to be very hot during the day and she may need to dabble several times rather than just one long foraging trip.

For those of you who are ‘sort of’ keeping up with Daisy, things have been relatively quiet for a few days. Today is day 13 of brooding. The WBSE ‘Dad’ made a surprise visit to the nest tree last evening at 16:59:24 but as quick as he appeared, he left at 17:03:43. I am sure he thought he would catch whoever was brooding in his nest. But Daisy has been very smart. And with the heat she may stay out foraging or dabbling longer. She landed on the rim of the nest at 19:49:49 but was very cautious looking around before venturing over to her eggs. In fact, she did not actually go over to the nest cup until 19:52, three minutes after arriving.

Daisy lands on the right side of the nest. She does not look at her nest and proceeds with caution in case there are predators about.
Daisy is listening and looking.

Daisy is very much aware that the White Bellied Sea Eagles come and go in the forest. Sometimes they stay for a few minutes, other times for many hours. She listens for the vocalizations from the other animals and birds in the forest to let her know if they might be coming. Her survival depends on it.

Satisfied that no one is around, Daisy sits on her eggs.
Daisy is busy as the sun sets and the Infra-Red cameras come on. Here she is fixing the down.

At 4:13, it is already more than 22 degrees C on the nest. Daisy is anticipating a very hot day. She has decided to go dabbling early before all of the other birds and animals in the forest are awake. You can see from the image below that it is still very dark in the forest. What we are learning is that Daisy, a Black Pacific Duck, can see in the dark better than the WBSE.

In fact, anyone observing this nest is learning a lot. No one can remember a Black Pacific Duck making their nest on a Sea Eagle camera or a place where we could easily observe without threatening the wildlife.

Daisy turns in the down and scatters the plant material around so no one will notice her eggs.

If you look carefully at the image above, you can see Daisy’s tail on the right behind the tree branch. She is just preparing to fly off to the water.

Daisy tucks her bill under her wing resting.

Daisy forages for a little over an hour. She returns to the nest and quickly bets on her eggs to incubate them. She rolls them with her paddle feet carefully and turns in the nest gently.

Daisy has returned from her morning foraging.

Daisy returns just after 5am. Sunrise is at 6:05. She knows that the sea eagles often fly into the forest at dawn. In the image below she has heard the sound of ravens. Ravens, you will remember, often chase the sea eagles. She listens carefully for several minutes before settling down.

Daisy raises her neck and listens for intruders.

By 8:30, Daisy has already had visits from at least one Sulphur-Crested Cockatoos and the Ravens were alarming at 8:04. Now the Rainbow Lorikeets can be heard in the forest but I cannot see them on the nest yet.

It is now after 10:00, and the sun is shining on Daisy in the nest. She has already starting panting in order to regulate her temperature.

The hot sun pounding down on Daisy.

It will be 36 degrees C in the forest today. It is understood that it is hotter on the nest. Look carefully and you can see Daisy’s bill open. That is her panting. The shade is ever so slowly moving over Daisy but the heat is almost unbearable. Instead of panting slowly, now it is a fast clacking of her bill.

Let us hope that it is way too hot for the sea eagles to be in the forest today. A day without sea eagles is a safe day for Daisy! And it is going to be so very hot that she doesn’t need a hassle with other predators either today.

Thank you to the Sea Eagle Cam, Birdlife Australia, and the Discovery Center for the camera that supplied the scaps of Daisy and her nest.

So far, all is well in the old Ironbark Tree, updated

It is Day 12 of Daisy’s brooding. Thank you for joining on this magical journey of the little duck who, instead of making her nest near the water, chose the great big nest of the White-Bellied Sea Eagle.

To 12 dzień lęgów Daisy. Dziękuję za udział w tej magicznej podróży małej kaczuszki, która zamiast założyć gniazdo nad wodą, wybrała wielkie, duże gniazdo orła bielika.

________________________________________________________________

It has been a very quiet and rather hot day for Daisy, the Black Pacific Duck whose nest is in the old Ironbark Tree in the Sydney Olympic Park. Thus far, the only visitors of any note today were the chattering Rainbow Lorikeets who came around 8am.

A friendly Rainbow Lorkeet curious about the little duck in the big sea eagle nest.

Yesterday, I mentioned that Daisy is in a category of ducks known as ‘dabbling’ ducks. The information that I had, at that time, was that they foraged along the shores of the rivers and lakes. This did not support pictures I have seen of them in the water hunting for food. So I looked for more information. One small informative page for children said that they mainly dabble at night. Photographs show them foraging during the day. And we know from Daisy’s behaviour that she goes out normally mid afternoon to feed. But we also know from our observations of Daisy that she can see well enough in the dark to come and go from the nest. That same bulletin stressed that the duck plunges its head and neck under the water, raising its rear end vertical to the surface. That is why one of the people working as a moderator for the Sea Eagle cameras said that when she saw the Black Pacific Ducks in the canal, all she could see was their back end. Now it all makes more sense. They also feed in grassy areas.

This is a domestic duck dabbling. I am using it as an example to show you what Daisy would look like if she were in the water foraging for food. Image courtesy of Wikimedia Commons.

Like Raptors, Pacific black ducks are monogamous. Males and females will stay together having only one partner until one of them dies. Their courtship consists of preening one another, flapping their wings, and bobbing their heads. While most Pacific black ducks build their nests near a source of water, we have learned from observing Daisy the Duck that she did not do that. So it is not always the case. Indeed, you might remember that a woman from Poland wrote to me about a duck making her nest also in an eagle’s nest. Those ducklings survived. The female lays from 8 to 123 eggs. If we look closely at Daisy’s eggs, they are white. Daisy will incubate the eggs from 26 to 30 days. That is two days shorter than the information I have previously posted. We know that they are precocial, able to feed themselves at birth. What I have not mentioned is that they will be fully independent of Daisy in 48-58 days after hatch. Daisy’s ducklings will be ready to find their own mate and breed when they are one year old.

One of the most beautiful parts of Daisy’s plumage is the speculum. It is a beautiful iridescent green. You can see it in the image above with Daisy and the Rainbow Lorikeet and in the image below. Depending on the light, the emerald green speculum sometimes appears blue or purple.

You can see Daisy’s green speculum clearly in this image.

And did you know that Daisy does not have any teeth? She has tiny serrations located along the inside of their bill that helps them filter out their food from the water. Daisy’s ability to sort out her dinner from the river water means that these serrations work kind of like a colander or a strainer!

It is 14:57 and Daisy has just left the nest to forage. I noticed two things about her departure just now. First, she covered her nest with the down folding it over like she has on other days but she did not spend as much time arranging leaves and plant material over the top of the nest. She also flew out a different direction to some days. Often she goes to the right but if she leaves from the left side of the nest, as she did today, she will be closer to the water. She must be very hot and hungry. She returned from her foraging last evening at 19:07 and has not left the nest since.

Daisy is preparing to fly off the nest on the left hand side today. She might be very hot. She has waited a long time for a break. Leaving from the left is the closest to the water.

I don’t quite understand why Daisy left and did not cover the down over the eggs with plant material, leaves, and twigs this afternoon. I wonder if it is because of the intense heat? She is always very meticulous about concealing the eggs well so predators cannot see them. And the wind is blowing. She was not scared from the nest. So, what do we think: was it the heat and the sun? she did not want the eggs cooked in the heat of the Australian summer?

Perhaps the nest is not covered so much and so packed down because of the intense heat in the forest today. 33 degrees C.

It has been a hot day and the forest has been relatively quiet. Daisy was incubating her eggs for twenty hours straight before taking her break. The weather report for tomorrow says that it will be even hotter, 36 degrees in Sydney.

A quick update: The White Bellied Sea Eagle called ‘Dad’ fly onto a branch of the nest tree at 16:59:24. He did a little preening. Never went down to the nest. Thank goodness as the wind had blown the down open and eggs could be seen. He departed at 17:03:43. I am so very glad that Daisy was not there or flying in. It does seem that this time of evening is the typical time he arrives. Well, he is gone now. Back to find some cool breezes off the water of the Parramatta River.

Please join us again tomorrow as we follow the life of this little Black Pacific Duck.

Thank you to the Sea Eagle Cam, Birdlife Australia and the Discovery Center for their camera from which these scaps came.

Day 11 of incubation

It is noon on Daisy’s nest in the Sydney Olympic Park forest. She has started to pant as the sun shines directly on her. Like other birds, panting is a way for Daisy to regulate her temperature; she does not sweat like humans. It is, as summer days go, hot. The weather at Homebush Bay indicates that it is 34.1 degrees C. I wonder if it is actually hotter on the nest?? It is normally understood that heat rises. And, as you can see from the image below, Daisy is in direct sunlight right now. Some parts of Australia are bracing themselves for very hot weather in a few days, up to 39 degrees C.

The hot sun at high noon is shining directly on Daisy.

Many have thought that Daisy would need to take more breaks during the day as the heat builds. However, since it is 12:30 and she remains, I am thinking that she will follow her regular pattern of going off in the afternoon to forage. She has now gathered up more down to cover up the eggs from predators.

At 13:18 Daisy begins to take the down of the nest cup and fold it over inwards. Sometimes she just does this and then will turn and do her cute tail wiggle. Occasionally, she does this when she is rolling her eggs but, most often, it is a sign that she is thinking about leaving to eat. Remember, Daisy does, if all things go serenely, have a pattern of leaving the nest between 1300 and 1400 to forage. Yesterday it was 14:02. And yesterday, she returned at 16:49 but noticed both WBSE on the camera tree and aborted her landing on the nest. So, on average, if voluntarily, it appears that she takes about a two and a half to a three hour break.

In the images below, Daisy begins to tuck the down in around the egg cup. Once the down is folded onto the top of the eggs, she then goes about placing leaves and plant material, and small twigs to further disguise the location. It took her eight minutes to get everything right so that she can leave. She departed at 13:26.

Daisy is busy folding the down that lines the nest cup inward.
Very methodically she continues folding the down in a clockwise direction.
After folding the down, Daisy begins to use her bill to bring in plant material.
It is not always easy to move the leaves and twigs with her bill but Daisy is tenacious.
Once she is satisfied that the eggs are covered as best she can, she leaves to forage to keep up her strength. It is very hot in Hornbush Bay and she needs food and water.
Daisy’s nest is nicely concealed.

All birds have predators and Daisy is particularly vulnerable as she is an outsider to the forest. Her presence and her seven eggs have caught the attention of some, like the Raven and Pied Currawong, that would eat her eggs. Like Daisy’s plumage that serves as camouflage, the manner in which she has concealed her nest is meant to distract any potential threats. She has used the leaves and plant material on top. They blend in perfectly, there is absolutely nothing that would call attention. Daisy is also very discreet and alert in her comings and goings from the nest. Every move is slow and calculated unless she is frightened off by the approaching sea eagles or if she notices their arrival in another tree. Then she leaves quickly!

This is day 11 of Daisy’s brooding or incubation. Even though the eggs were laid on different days, Daisy did not start hard incubation until the last egg was in the nest. Imagine that one minute there are eggs, and within a few minutes the nest will be brimming full of peeping and clacking ducklings. This is precisely what will happen. This is known as synchronized hatching. The number of incubation days to hatching varies but is normally 28-30.

Daisy’s little ducklings – should the nest survive and they make it through the forest to the water – will be covered with fuzzy yellow down. They will have a characteristic dark chocolate brown-black line running from their bill through their eye. There are some white patches on their wings. They will be ever so cute!

Black Pacific Ducklings

Daisy’s ducklings are precocial at hatch. This means that they do not need Daisy to feed them. Daisy’s role will be to lead them to the water where they can forage themselves. Daisy will also help them to learn about predators and she will keep them warm in the evening. In a couple of months their new plumage will be that of an adult Black Pacific Duck, like Daisy.

They are known as ‘dabbling or puddle ducks’. They feed by tipping rather than diving to the bottom of the shallow water. They often forage at the edge of the river and lake like they are doing in the images below. They do not, however, hunt for food on land.

It is due to be another hot day in the forest tomorrow. The prediction is that it will be 37 degrees Celsius. This might turn out quite well for Daisy as the White Bellied Sea Eagles could be at Goat Island enjoying the cooler weather near the water. It is 16:42 and Daisy has not returned to her nest. She will be enjoying the cool waters of the canal and the river and, since it is so hot, might decide til near dusk when it is safe for her to return to her nest. The sea eagles are normally roosting then.

An uneventful day is a good day for Daisy the Duck.

Thanks for dropping by to check on the little duck who is occupying the large sea eagle’s nest in Sydney Olympic Park forest. Stay safe everyone. See you tomorrow!

I am grateful for the Sea Eagle cam, Birdlife Australia, and the Discovery centre for the cameras they support. This is where I get my scaps.

Quite a fright

Late yesterday afternoon Daisy arrived back at the nest right before 17:00. In a split second, she saw the two WBSE on the camera tree and was able, quickly, to abort her landing. They scared Daisy. She stayed away only returning at 19:43 as the sun was beginning to set on the old Ironbark forest.

And if that wasn’t enough of a fright, in the wee hours of the night she was literally scared off by sounds coming from the nest. Daisy was so frightened she quickly flew off after listening for a few minutes. And that scared off the Ringtail Possum that was climbing up the nest peeking in at Daisy sleeping in the sea eagle nest. It seems they both scared one another.

Common Ringtail Possums are small. They are about the size of a medium domestic cat. They are grey with some white behind the eyes with a white tip on their tail. They use this tail almost like a fourth leg wrapping it around branches to help them climb. They are forest dwellers and are very familiar with the sea eagles that raise young on this nest. Many people think they have their nest at the very bottom of the sea eagle nest. Like BooBook Owl and the more threatening Common Bushtail Possum, they hunt at night. They are vegetarians feeding on plants, fruit, and flora. The little Ringtail possum is the only species of possum in Australia where the male is actually involved in caring for the young possums. They are, again, not as much a danger to Daisy as the Common Ringtail Possum.

The possum that Daisy should be very fearful of is the Bushtail.

Brushtail possums are the most widespread marsupial in Australia. (They are also in New Zealand). They are brown and have really bushy tails with a underneath furless patch that helps them to climb trees and hang on to the branches. They hunt at night and eat leaves, flowers, fruits, insects, small animals, and eggs. They are not related to the Opossum of the Americas and they are not the benign fruit eater portrayed by many books. They pose a real problem to Daisy as they are, as noted earlier, keen egg eaters. These possums are known to have eaten parrots, keas, robins, as well as larger kiwis. Researchers believe the decline of the North Island Kokako (endemic to New Zealand) to almost extinction was caused by the Brushtail Possum. The Kokako is a large grey-blue song bird. It has a black mask and long legs. New Zealanders are working hard to restore the populations of these lovely forest birds.

It is now past dawn in Sydney, Australia. No sign of the White-Bellied Sea Eagles. Daisy is setting serenely on her nest. You will notice that she has been bringing in some of the down that was scattered. The nest is quite fluffy now!

Daisy, after dawn, January 22

There is absolutely no telling what comings and goings will happen today. It is Day 10 of brooding!

Dawn casts a beautiful rose-gold over all the forest.

Dawn

And just about the time Daisy settled into a quiet early morning, she heard something land on the camera tree. It is 7:18:48. Too late to get off the nest or cover the eggs, she decided the right thing to do was to freeze flat.

Daisy lays ‘frozen’ hoping that the large bird on the camera tree does not see her.

Whatever it was, it was, its shadow indicated that it was a large bird but not as large as a sea eagle. Spotters said it was white so it is likely not then the Raven who continues to come, hoping to find Daisy gone and eggs for dinner. The bird left in about ten minutes but Daisy stayed frozen like she is in the photo above. Gradually, she began to relax.

Daisy relaxing slowly.

The first threat of the morning has come and gone after the excitement of the possum who came during the early night.

Stay tuned. An updated post will come in about six hours. Stay safe. Thanks for dropping in to check on Daisy.

For birds and ducks, it seems that the term ‘hawk eye’ really applies, updated

I have to make a confession. It has been a long, long time since I ‘considered’ ducks, ducks of any breed. As a young child, I had a pet white domestic duck that my father brought in his pocket one Easter. Along with a hoard of cats, a three-legged dog, the duck was one of my greatest companions. I spent much time at the zoo but where I really loved to go was to the ‘Duck Pond’ at the University of Oklahoma.

Fall on the University of Oklahoma and part of the large duck pond.

Hours and hours were spent feeding the ducks and just sitting and looking at them. When I visited with my children, they, too, learned to love all of the ducks at the Duck Pond. It is an institution in Norman, Oklahoma, that Duck Pond. I have no idea how long it has been there. It is much beloved and I continued to visit it until the very last time I was in Norman. But I haven’t actually thought about ducks. Hawks, yes. A Sharp-shinned hawk visits my garden regularly in such of prey. The garden is full of birds that can attest to my devotion to feeding them and I have written extensively not to feed birds of any kind – crows, our Canada geese, the ducks at our duck pond at St Vital Park – bread. Feed them corn and peas. Crows love hard boiled eggs, dog kibble, and grapes. But ducks did not get into my head until Daisy. When she first came with her mate in December to check out the nest of the WBSE, I didn’t think too much of it. But, it is what I have learned watching her, talking with others, and researching that has me totally enthralled. I hope you are, too. Just some facts that astound me. Daisy will have lost half her weight in creating the eggs and brooding. They also have the calcium in their system partially depleted. It is hot in that seventy-five food high nest in Sydney, Australia and they tell me it is going to get hotter in the next few days. While this helps the eggs to stay warm when Daisy has to go forage, it also means that she must hydrate more often. Each time she leaves the nest, the eggs are vulnerable. Today before leaving at 14:02 for foraging and a cool down, she gathered up some of the down that the WBSE and the Pied Currawong tossed. She put some of it on the nest but the wind has been blowing and one of the eggs appears to be exposed.

Daisy has been slowly pulling the down that was removed by the WBSE and the Curra closer to her nest cup.

The exquisiteness of her nest woven with nothing but what she has found left on the sea eagle’s nest – leaves, sticks – and the down she pulled from her breast was nothing short of remarkable. A contemporary artist would have difficulty coming up with something so beautiful and organic if they tempted to replicate her work.

And I admire this little duck more than I can ever say. Is it the old David and Goliath story? Think about it. This is a little duck who knows nothing about the forest. She has, for all purposes, made her nest in the ‘King Pin’ of the forest, Dad, the White Bellied Sea Eagle’s nursery!

The last visit that Dad paid to check on his nest was on January 18. That was three days ago. That day he stayed for about six hours waiting for the intruder to return. He did not realize how smart our little duck is!

There are Ravens and Currawong that would destroy her nest and eat her eggs quickly.

Daisy is one brave little tenacious duck, intent on brooding her eggs and having ducks jump over the edge and make their way to the water with her. On the way, if we make it to that point, there are other dangers including foxes. As a result of watching her, my admiration for all of the birds has grown immensely and I want to know more about them and how I, someone writing a blog on the cold Canadian prairies, can help them.

Today, Daisy left well before dawn to go and forage and cool off. It was 4:20am. She returned an hour later, about forty minutes before dawn. Most hawks, falcons, and eagles will venture out at dawn and settle to roost at dusk. That, of course, does not apply to birds like owls who hunt at night. My question is how can Daisy manage in that light? It seems that she might be creating a pattern of leaving before dawn and right before dusk to forage with a break in mid afternoon. But, I cannot say for certain. It will take more days to make that kind of a generalization. But what about her vision

Daisy is back at her nest before dawn. Note that she has one eye on each side of her head. They are not situated together on the front of her head like humans.

Almost all birds have some of the most sophisticated and advanced vision of any animals. And their eyesight is much better than humans! Ducks, like Daisy, have monocular (single) vision. Humans have binocular (stereo) vision. Look at Daisy. Her eyes are located on the side of her head. She does not see in 3-D like we do but, if you have ever noticed a duck or a raptor bobbling their head back and forth, that is what they are achieving but with more precise sight than we ever could have without the aid of a device like a powerful spotting scope. Our eyes have blood vessels. Ducks do not have blood vessels in their eyes. Instead their blood is contained in the pecten. The pecten is a small organ at the back of their eyes that contains the blood. Daisy (and other birds) also have something else that humans do not have, panoramic view. She can see almost 360 degrees. This really helps to protect her from predators. So to sum, it up, ducks have eyes that are capable of seeing at least two or three times farther than humans. Their eyes have other characteristics to help them survive in the wild. This includes being able to see ultraviolet light because their eyes have cones. It is also known that they are very good at differentiating colours which, luckily for them, causes duck hunters many problems. They can tell between someone wearing camouflage that isn’t quite the colour of the environment that surrounds them. Good for you Daisy and all Ducks. You might just outwit the hunters. And, speaking of hunters, many in Australia are saddened by the new duck hunting laws for 2021 after seeing Daisy.

Along with her excellent sight, Daisy relies on her hearing. While she is relative unfamiliar with many of the animals and birds who live in the forest (remember she normally lives by the river, not in the forest), she does listen for vocalizations. She tends to raise her neck if she hears alarm calls by other birds nearby. A good example is the calls of the Raven because the Ravens tend to follow the sea eagles if they enter the forest. The ravens are not a direct threat to the WBSE but they are an annoyance. And, of course, Daisy often sleeps with one eye open!

Daisy raises her neck high to listen.

Notice how Daisy raises her neck high in the image above. She can never really relax completely. She must always be alert to any noises or disturbances that might threaten her. On occasion, she has had to leave very quickly and has been unable to cover her eggs. That is what happened the other day when Dad the WBSE arrived on an adjacent tree and she has to leave very quickly. It was that same day that the Curra tried to eat the egg that Dad had rolled out of the nest cup.

Daisy literally sleeps with one eye open so that she can not only hear but see any predators.
Late afternoon shade is almost completely covering the nest.

So far, since Daisy left to forage around 14:00, no predator has arrived at the nest to do harm. In fact, the forest is relatively quiet. Most of the activity occurs at dawn and at dusk. It is a good time for Daisy to forage. As it hears 15:30, Daisy should be returning within an hour and a little bit to start her brooding. She might, like last evening, sneak out for another dip in the water to cool her off before dark.

Thanks for coming to read about and check on this precious duck. She is, according to locals, the first bird that has ever made a nest in the White Bellied Sea Eagle Nest in the Sydney Olympic Park. She is one brave duck and there are thousands of people watching and wishing her well.

Stay tuned for an update in the morning. Nite all, stay safe.

Well, thanks to Daisy’s good eyes and quick reflexes. She was flying into the nest around 16:49 when spotted ‘Dad’, the White Bellied Sea Eagle landing on the branch of the nest tree! She aborted her landing very quickly. Dad had arrived with Lady around 16:01 and both were on the camera tree. One of the sea eagles left and another flew to the parent branch of the Ironbark Tree. See the images below. It is quite windy and hot and the eagle is busy looking around everywhere from his perch. Did they see Daisy?

Dad? Lady? is using his ‘Eagle Eyes’ to look around everywhere hoping to catch the bird who is brooding their eggs in his nest!

The wind was blowing frantically. The WBSE left at 16:58. Where did they go? Neither went to the nest. It looks like it was a quick fly in to see if they could catch the intruder. It is difficult to say if it was Dad or Lady who remained behind. They looked a little ragged suggesting that it is Lady who has not finished their moult. Maybe they left to catch some fish before dusk. Spotters on the ground say that Dad and Lady have returned to their River Roost on the Parramatta River.

Wonder if either will return to check on the nest again? Remember, their vision. They will not come after dusk! The only bother for Daisy during the night is BooBook Owl.

Wind gusts blowing Dad’s feathers ever which way.

Thank you to Sea Eagle Cam, Birdlife Australia and the Discovery Centre for providing the camera for my scaps.

Galah and more Rainbow Lorikeets come to visit Daisy!

Yesterday afternoon Daisy the Duck, the current ‘illegal tenant’, if you like, of the WBSE nest in the Ironbark Tree in the Sydney Olympic Park forest, went for her usual break to forage in the canal and the Parramatta River nearby. Right before she left a couple of Galah decided to come for a visit. Daisy has had a lot of curious visitors!

Galah are also called the ‘Pink and Grey Parrot’ or the Rose-Brested Cockatoo in Australia. Galah is the Yuwaalaraay name for them, a native language, where the word means ‘fool’ or ‘clown’. They are highly intelligent and are said to make very good pets. That said, anyone who has spoken to me about them in relation to the Peregrine Falcons and Sea Eagles of Australia, thinks they are not very smart. I was told that if you visit Australia and someone calls you a ‘Galah’, it means they are saying you are stupid. Remember that if you travel ‘down under’. Galah eat plants and insects and would not harm Daisy or her eggs. They are, like the Rainbow Lorikeets that also visited yesterday, curious about this new bird in the forest who is brooding eggs in an active sea eagle nest (off season for them now).

She returned to her nest to brood her seven eggs and then, she took another break, returning around dusk. Save for the arrival of a host of Rainbow Lorikeets and the sound of ravens nearby that caused Daisy to lay flat and still for over half an hour, her day brooding her eggs was relatively uneventful. The WBSE did not show up and none of the animals or birds living in the forest bothered her eggs. Even BooBook Owl did not show up in the middle of the night to go ‘bump’.

But something very odd happened the morning of January 21. Daisy covered her eggs, as best she could, pulling down and leaves and even small sticks over it, and left the nest around 4:25 am. Sunrise is at 6:05. That is when the WBSE come, if they do, in the mornings. Why so early?

Daisy leaves her nest at 4:23. She returns in about an hour, before dawn arrives.

The leaving of the nest at 4:20 and returning an hour later leads me to wonder about the eyesight of the Black Pacific Duck. The sea eagles fly right at or after dawn when they are about. They come back to the nest or their roost at dusk. But Daisy is able to come and go when it is dark. Plan to do some research on the eyesight of ducks. Daisy is similar to a Mallard and that might help me. If you know about the difference in night vision, please leave me a note. It would be much appreciated!

So far, it has been a pretty uneventful morning for Daisy and that means it is a great day for a little determined duck brooding her eggs.

Around 9 am the visitors begin to show up. First are the curious Rainbow Lorikeets and then you can hear but, not see, the Ravens. The Lorikeets or Loris are chattery and loud and very curious but they will not hurt Daisy, her eggs, or her ducklings. But the Ravens will. Daisy always places her body really low on the ground when the Ravens are about.

Daisy can hear the Ravens. When she does she begins to lower her head to be flat with the base of the big WBSE nest.

Daisy gets low and really still, just as if she is frozen. Soon, the Ravens disappear. Not only would they eat the eggs but, the Ravens also chase after the White Bellied Sea Eagles. They are, often, a warning of their approach.

Daisy is frozen waiting for the Ravens to leave.
Daisy is relaxed, brooding her eggs.

It is even quiet enough for this busy duck to catch a few zzzzzs.

It is 10 am in the forest and all is quiet. The WBSE were seen at Goat Island last night. Maybe they will stay there. It is a nice vacation time for them with no eaglets to raise and both are moulting which causes some distress. That would be good for Daisy. She can rest all day like she is now incubating her little ones.

Stay tuned for updates later in the day. Have a good one.

A Tree full of Rainbow Lorikeets

I was reminded yesterday that Daisy the Black Pacific Duck is not normally an inhabitant of the forest. She lives down by the water and would, at most other times, make her nest on the ground. She would shape grasses and other plant material into the egg cup or bowl. It is only once she has started hard incubation, that Daisy, like other ducks, will pluck the down from her breast and line the nest. She will continue to add plant material and down to the nest as needed, often replacing what others pull out and destroy.

This year, Daisy didn’t make her nest on the ground. Instead, her and her mate selected a very old nest in an Ironbark Tree in mid-December. That nest belongs to the White Bellied Sea Eagles whose territory is around the Parramatta River and the Sydney Olympic Park forest.

Daisy would have had many intruders if her nest were on the ground. But she would have been familiar with them and they with her. Because she is brooding her eggs in the forest, she is a curiosity. The birds and animals that live there do not know about ducks. They do know that it is the sea eagles that raise their young in this particular nest. Of the curious, one of the first was the the Pied Currawong who, unable to eat the exposed duck egg, threw a little mini-tantrum pulling out much down from the rim of the nest and tossing it over the rim of the sea eagle nest. Others who have come to the nest to check out Daisy have been the BooBook Owl, possums, Ravens, and Sulphur-Crested Cockatoos.

Today, the Rainbow Lorikeets returned. They are the most colourful parrots in the forest! They are ever so curious about the duck in the sea eagle nest! Oh, not just six or seven, but dozens of them! And Daisy was not sure she liked them getting close to her and her precious eggs. Rainbow Lorikeets are a medium sized parrot that are plentiful along the east coast and southern part of Australia. Unlike Daisy who has a bill, they have a beak. They are nectar feeders and are no threat to Daisy. But she doesn’t know that! And like any mother, she will protect her nest and her young as best she can.

At first, it was only three (one out of the picture frame). They were a little cheeky and one of them, totally curious as to why a bird they had never seen should be in the eagles nest, crept over close to Daisy. Daisy turned around in her nest and away from the pleasant morning she had been having and ruffled her feathers and readied to defend herself against birds that she had never seen also. She did not know if they were looking for insects in the nest or if they would harm her.

One of the rangers that researches the nest of the WBSE said that the Rainbow Lorikeet were there to give Daisy the Duck a lecture about not making a nest in a nest owned by sea eagles. But, alas, it is too late if that is what they are doing. Daisy is now on day 7 of incubation duties. She is devoted to her duties!

One of the Rainbow Lorikeets got very close to Daisy and Daisy was contemplating what to do to defend her nest.
At first there were three and then more came until there were more than a dozen chattering away non-stop.
Two Rainbow Lorikeets sat on the rim of the sea eagle nest chattering directly at Daisy who is watching them carefully.

After all of the commotion – and it really was a boisterous affair – with the Rainbow Lorikeets everywhere, Daisy settled into a little bit of nest renovation. Remember the Curra and Dad the Sea Eagle had moved down off of the nest. Look at how far Daisy can stretch her neck. I had no idea looking at her that her neck could get so long. She also used her bill to help gather up some down and plant material that had scattered.

A bill of a beak? Ducks have bills. They are very lightweight. The exterior coating over the interior spongy bone is made out of the same material as our fingernails, keratin. And just like our fingernails, the keratin covering is always growing, healing over dents and scratches, but also maintaining its shape after much use. Ducks do not have to go to a nail salon for a trim!

Look at how far Daisy can stretch her neck!
Daisy is using her bill to bring in some of the down the Curra removed from her nest.

After nest renovations, Daisy takes some time to do some preening. Daisy’s feathers are very important to her. She is a ‘diving duck’. That means that she submerges under the water to find food. For ducks like Daisy, it is essential that their feathers be in prime condition. Many types of birds spend up to seventy percent of their time preening, conditioning their feathers. Daisy’s beautiful feathers have grown very tightly. The feathers are stiff and are quite strong compared to the down. In fact, people used to use the feathers as quills to use with ink for writing. Daisy’s feathers grow close together and overlap one another. Look closely and you can see this. They make many layers that are weather resistant and protect our duck.

It is nearly 11am in the world of Daisy. Dad the Sea Eagle did not show up at dawn to try and catch the intruder using his nest. Daisy has decided to try and rest a bit. She is still very alert.

Will Daisy take time in the heat of the Australian summer to go and forage? Will she voluntarily leave covering her nest? Will Dad come at dusk? We wait.

Day 6 of incubation, updated

Daisy returned to her nest at 17:50 after spending most of the day away. If you are following the sage of this little Pacific Black Duck, you will know that yesterday, ‘Dad’ the White Bellied Sea Eagle owner of the nest arrived at dawn and stayed for some six hours before departing. During that time he did mess up a little of the down but, for the majority of the time, he stood sentry duty. Dad would, of course, really like to catch the bird that has violated his territory! Because Daisy had to leave so quickly, she was unable to cover her nest. A couple of hours after Dad departed, a Pied Currawong arrived at the nest and tried to eat an egg. Unable to do so, that bird threw a bit of a fit tearing the down from around Daisy’s carefully created nest and throwing it over the rim of the sea eagle nest. It was warm in Sydney yesterday and the sun shone on the nest for extended periods. Someone also told me that because of the way the sea eagle nests are constructed they hold the heat much better than ordinary nests. Let us hope so and also that the sun’s heat did not do any damage. Daisy is brooding seven eggs. They should be ready to hatch in about three weeks.

After all of the hassles yesterday, it was nice when Dad Sea Eagle did not show up at dawn! As a result, despite the wild gusts of wind exceeding 26 km an hour on the nest, Daisy was able to relax and nap.

Daisy rests but keeps alert to anyone approaching her nest.

Daisy has had a quiet day on the nest so far. It is day six of her brooding. She has lost approximately half her weight laying her eggs and I understand that she has pulled half her down out to line the nest. Raising little ones takes its toll on mothers. Some bulk themselves up before laying their eggs. Again, I was told recently that the birds use up a lot of their calcium stores for the egg shells.

This reminds me about bird seed at your feeders for winter. You should be feeding the birds the black oil sunflower seeds. It helps give them fat to burn during the winter. It wouldn’t hurt to get a bird seed with added calcium and put it in your feeders several months prior to breeding in your area. This will help the female build up her calcium stores and help with the thickness of the eggs. That protects them from being broken easily. Some people crush the shells of the eggs they have eaten. But know that if you want to do that you need to wash the shells thoroughly to get rid of any bacteria from the chickens who laid them. Then you place them in a shallow pan and bake them at 325 degrees F for 20 minutes. You could save up a bunch and bake them the next time you used your oven.

A close up of the beautiful nest made of Daisy’s down and plant material from the sea eagle nest.

Daisy started moving plant material and leaves toward her nest around 1pm. She left the nest at 13:22 to go and forage near the Parramatta River that runs through Hornbush Bay, Australia. It is unclear whether or not she will return in a couple of hours or if she will wait as dusk begins to arrive. The last time she left volunatarily to forage at mid-afternoon, she returned and twenty minutes later, Dad Sea Eagle showed up and she has to fly away and wait until dusk to return.

Daisy carefully covered her nest with down before leaving to forage.
Daisy voluntarily left the nest to forage and carefully concealed her nest.

One thing that is worrisome is that there are ravens about today. They love eggs and are very smart. Daisy did a good job of covering her nest today. Hopefully they will not find it!

I also want to thank the individual who wrote to tell me about a nest in Poland. A Mallard laid its eggs in an eagle nest. They successfully hatched! Isn’t that wonderful? I wonder if it was an unoccupied nest? The individual told me that the Mallard did not have any of the hassles that our Daisy is having trying to brood her eggs. The story from Poland gave me hope!

QUICK UPDATE: Daisy returned to her nest at 15:51 without incident. She was cautious, listening for anyone who might be around or who might have followed her. A very wise woman said today that all of the creatures in the forest would be curious about Daisy because she normally doesn’t live there. She lives on the water. Of course. Let’s just hope that curiosity is all that is going on!
