Noisy Ravens come to call on Daisy

It is a soggy day in Sydney, Australia. Rain is falling and the temperature is 20 degrees C. What a change from a few days ago! Wish I knew if Daisy liked it cooler or hotter. Do ducks have a preference? They certainly don’t mind water and their down nest would get wet if Daisy built in on the ground.

For those of you dropping in but who haven’t been able to catch up with Miss Daisy’s news, I want to focus, for a bit, on the impact of the showers and WBSE Lady’s tearing the down off Daisy’s nest. Daisy doesn’t look like she is sitting on that lovely fluffy nest any longer. Daisy has collected all of the tossed down that she could – which was a lot – and has brought it back onto her nest. Just as quickly as it dries, it rains again. Then the eiderdown gets soaked and turns into a soaking blob. The heat from Daisy’s body will eventually dry it but the forecast is for four more days of rain and cool weather.

There is that saying that a picture is worth a thousand words. I am a very visual person as I imagine many of you are. So I am posting two images in order for you to easily see the impact that rain has on the eiderdown that Daisy has plucked off her breast to line her nest. The top one shows Daisy on her nest when it is dry. Notice how thick and fluffy the eiderdown is. Daisy looks like she is brooding on a cloud.

The image below is not focused but you will still be able to see the impact of the rain on the insulating down. The down is no longer fluffy. The wetter it gets the more it loses its volume. You can also see that the eggs can no longer be covered leaving them vulnerable to predators. Daisy does try hard to move other plant material on top. She has only so many leaves to use. If you think about it, she has not pulled any twigs over her eggs. She might intuitively know that those sticks of wood could break her eggs.

It is right after noon on the nest and it has been a relatively quiet morning for Daisy. She did have several visits from Ravens that sent her hunkering down on her eggs. They flew back and forth around the nest tree and into the forest and back again for about fifteen minutes. They were not chasing the sea eagles but when Daisy hears their caw she really pays attention.

After the Ravens had their turn disturbing Daisy, the Butcher Birds came to the nest tree. Butcher Birds are songbirds. They are similar to Magpies. The grey ones only live in Australia. They have a dark mask or an eye stripe just like Daisy! It is thought that these black stripes or masks help to block the sun for the birds so they can hunt or dabble better. If you know about American football, you might have seen the players smearing a black substance under their eyes. That also helps with the glare and I bet, a long time ago, humans learned that trick from birds. They have brown eyes and legs. The pointed beak, with a hook, is also grey. They can be very aggressive. They live in forests and mangroves feeding on insects and small mammals, fruits and seeds. They are known to also eat lizards or other small reptiles.

Daisy waits to go dabbling and to the bathroom. Around 15:31, she begins to gather the leaves and tuck in the down to try and cover her eggs as best she can.

She is in no rush. The ravens and the sea eagles are not about. She can take her time. Because it is cool, she will want to try and get as much insulation as she can over the eggs along with the leaves that she has been pulling toward her all day.

Daisy leaves her nest at 15:31:45.

Despite the down being somewhat soggy in places, Daisy does a really good job concealing her eggs. Notice the two identical leaves across from one another. Daisy has done a marvellous job at decorating her temporary nest with the terracotta covered foliage.

Eggs are concealed with down and leaves.

So far, except for the anxiety produced by the Ravens’ visit, Daisy has had a relatively quiet day. She has waited til later today to go hunting for food. It is now 21 degrees C and 100% humidity with rain. Sun set is around 20:04. That is four and a half hours away. It is certainly safer for Daisy to go foraging as late as she can because she would miss the sea eagles if they came right before dusk. However, WBSE Dad has been known to show up around 17:00 on several occasions. Let us hope that no one comes, the eggs stay covered, and Daisy returns in about an hour and a half. Hopefully those eggs will still be warm. It is too bad we can’t somehow slip a little electric or solar blanket in that nest for them!

Thank you for stopping in to check and see how Daisy is doing. It is currently day 17 of incubation. The hatch window opens on day 26. So many did not believe that Daisy would still have a nest or any eggs. No one knew how the sea eagles would react. Many thoughts the ravens would force Daisy off the nest and they would then devour the eggs. But so far, none of that has happened. The sea eagles have been confused and have not harmed the eggs other than the one dad ate. So, there could be hope for some of the eggs to be viable. Oh, wouldn’t it be wonderful to see the little fuzz balls jump off the old Ironbark Tree nest? Ducklings born in a big sea eagle nest. Puts a smile on your face!

Thank you again for joining us to find out what is happening with the brave little duck whose nest is in an old Ironbark Tree in the Sydney Olympic Park forest. We are so glad you stopped by.

Thank you to Sea Eagle cam, BirdLife Australia, and the Discovery Centre for the streaming cameras where I captured my screen shots.

Daisy ducks!

No sooner than I had posted my last update on Daisy, than the little duck got busy covering her eggs and going to forage. The time was 14:41:26. It is in the normal range of when she leaves the nest. Sometimes she has not returned until dusk because she knows she will avoid the sea eagles. Now that she is getting nearer to hatch, will she stay away that long?

Covering the nest

As she leaves she finds some down that she has missed when restoring her nest. She loosens it from the twigs and pulls it down to the floor of the nest.

This time Daisy has tucked the down and added some leaves at the side. She tried to fold the top onto itself but not getting it tight like she did during the early stages of her incubation. Let us hope that the gusts of wind do not pull the down apart leaving the eggs open to eating or destruction by the Ravens or the Currawongs.

You can compare the next image below to the one right above. Look at the fluffy light down. Looks like it has twinkly stars embedded in it.

Well the rain became heavier and made its way through the canopy of leaves.

There isn’t much difference in the image above and the one below except for the down covering Daisy’s nest. It has begun to rain just a little harder with more of the drops making their way through to the nest. Daisy’s nest looks so wet and so sad without her in it. It is 17:50. Wonder how much longer she will stay away? It is 20.3 degrees and rain is forecast through Sunday.

The protective down gets very wet.

Daisy returned to her nest at 19:03, an hour before sunset. She was a very wet duck! The nest was soaked and the down was a solid wet glob.

Daisy is a little soaked.

Daisy settled in at the task in hand. Daisy was away from the nest for five hours. The sea eagles did not return at dusk. Whew! But, two hours later, once it is dark, BooBook Owl comes to call and scares Daisy by flying from branch to branch.

Ducking!

Daisy flattens herself over her eggs increasing the size of her body and extends her neck. She is in protective mode. Boo bothers her for about a minute and a half and Daisy goes back to incubating her eggs.

The old Ironbark Tree where Daisy’s nest is located.

It is now 7:34 in the Sydney Olympic Park. The heat from Daisy’s body and the wind have dried out the down. The sea eagles did not arrive. They have been spotted at Goat Island. That does not mean that they will not return. It just meant that Daisy didn’t have to scurry from the nest before dawn. A good way to start the day, nice and relaxed.

Daisy and the down have dried. Rain is forecast for today.

It may look boring but a boring, quiet day without any visitors to Daisy is a good day! Let us all hope that it stays that way for her.

Yesterday, some of you noticed that Lady didn’t like the down. It looked like is was sticky. Now we know that sea eagles do eat birds so, Lady would be very familiar with feathers. But she might not know about eiderdown. This is what I was told from someone very familiar with ducks and geese, “Cling is an attribute of eiderdown and very mature goose down, also known as”sticky down”. “Cling” is found when tiny hooks develop on the individual filaments of a down cluster”. I immediately thought of Cling film that we pull over bowls and things to keep food fresh. It sticks to itself and to the bowl. Well, that is precisely what Daisy’s down did to Lady. It must cause Lady a lot of confusion. And, you know what? That is OK. I know that this is Lady’s nest where she raises her eaglets. But Daisy is not a threat to the sea eagles or their babies. Yes, she chose their nest but this might have been because she lost all of the ducklings in her first brood this season and she wanted to see if this nest might help see some of them to hatch. I know that each and every one of you are cheering our little duck forward.

One of Daisy’s fans also sent a video for all of you to watch. A Mandarin duck made her nest on the balcony of an apartment twenty-stories up from the ground. It is an amazing video showing how the people of this city came together to help the ducklings. Have a look!

Daisy wants to thank all of her friends wishing her success. People have joined her from Canada, the United States, Australia, Mexico, Poland, Croatia, China, the United Kingdom, and Brazil. Check back for updates. We are getting closer and closer to hatch!

Thank you to Sea Eagle cam, Birdlife Australia, and the Discovery Centre for providing the camera for the screen captures.

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.

WBSE ‘Dad’ trying to catch the intruder in his nest. No luck today, Dad! Sorry.

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.

Wonder what will happen today on ‘As the Nest Turns’?


Before I begin today, I want to thank all of Daisy’s fans from Poland who come every day to check on her well-being. It is so nice to have you with us on her journey.

Zanim zacznę dzisiaj, chciałbym podziękować wszystkim fanom Daisy z Polski, którzy codziennie przyjeżdżają, aby sprawdzić jej samopoczucie. Miło jest mieć cię z nami w jej podróży.

__________________________________________________________________

I have to admit that the time difference between the Canadian Prairies and Sydney, Australia often means that I am awake at 1:30 am waiting for Daisy to return to the nest from foraging. Last night it caught up with me and I turned out the light. Daisy is being smart. She waited til the sun was beginning to lower itself before returning to the Ironbark Tree. It was 17:07.

Daisy approaches her nest cautiously. Remember, she has, at the last minute, looked up and glanced the White Bellied Sea Eagles sitting stone cold still on the camera tree and had to leave quickly. I am impressed with her approach. She lands on the old creaking tree, stopping and looking, and slowly proceeding to her nest. Someone might think she is just a curious visitor. But we know better! So far this little Black Pacific Duck has outwitted the sea eagles!

Daisy continues to be cautious as she slides onto her nest.

The sun lowering on the horizon leaves a beautiful filtered light on our beautiful little duck. For those of you who have been following along every day on Daisy adventures, you will notice that she is really cleaning up the down that was tossed about and getting it back on the nest.

It is 4:40 am in Sydney and Daisy is enjoying the cool before the heat of the day arrives.

The Homebush Bay weather says it is now 21.9 degrees C at 5am. It is expected to climb to 33 degrees C at the height of the day. Oh, Daisy, it is going to get pretty toasty on that nest!

In an article for the Smithsonian Magazine, Brian Handwerk says in ‘Defying Stereotypes, Ducklings Are as Clever as They Are Cute’ that “a duckling’s ability to imprint confers a remarkable ability for abstract thought, often associated only with primates and other animals considered highly intelligent. Ducks even outperform supposedly “smarter” animal species in certain aspects of abstract reasoning. Just hours after birth, those yellow fuzzballs understand concepts like “same” and “different,” remember them, and apply them to never-before-seen objects with no social cues or training” (14 July 2016). In being able to distinguish likeness and difference, the ducklings are demonstrating that they are not ‘bird-brained’ but, rather, they have a high level of abstract thought.

I was so glad to see someone writing something positive about ducks. It isn’t that I have found negative statements about ducks but, rather, it is the absence, the invisibility of ducks in recent popular books on birds. For example, in Jennifer Ackerman’s, The Genius of Birds, there is not one mention of a duck! Magpies, yes. House Sparrows, yes. Even one little mallard, no. I would like to think, from observing Daisy, that ducks are as capable of complex behaviour as every other bird discussed in the book. I think that you might agree with me. She has, thus far, outwitted the boss of the forest, the largest seabird in Australia, the White Bellied Sea Eagle. Let us hope that this pattern continues!

I begin to look at my bookshelves and realize that I have been focused entirely on Red Tail Hawks and falcons. There must be as many beautiful books on ducks. Surely people have adopted ducks, made ponds for them and feed them in the same way that people in the English countryside have swans or wildlife rehabbers have Red Tail Hawks. Perhaps you know of some books on ducks that I should read. Lists are always appreciated. When I looked on line, there are pages and pages of children’s stories about ducks and geese. There are some about making duck decoys and how to line them up so that ducks can be shot. Sorry, I don’t wish to shoot them. I would like them to live happily in a pond or at the edge of the water like our Dabbling Duck, Daisy.

It is 5:57 and the forest is beginning to wake up. Daisy hears ravens cawing in the distance. Ravens normally follow the sea eagles in the forest. She stretches her neck to listen intently and then relaxes again.

There are enormous demands and dangers for Daisy while she is nesting. She has pulled off the down on her breast to line the nest. This also creates a bare spot which is the ‘brood patch’. The heat from Daisy’s body goes directly to the eggs. Periodically during the day and night, she will rotate the eggs. Daisy has, as mentioned before, lost a lot of her body weight creating the eggs and lining the nest. She also is not able to go and forage as frequently as she would when she is not nesting. We know that she goes out to replenish herself but that is on average about three hours a day. Otherwise, she is alert and on the nest tending to her eggs. Daisy is not like larger waterfowl, like geese and ducks. She does not have a fat reserve to draw on when she is incubating. So besides the danger of her own health, there are also other animals in the forest that are predators. We have met many of them in the days that Daisy has been incubating – Ravens, the White Bellied Sea Eagles, the Pied Currawong, and perhaps BooBook Owl, Magpies, and possums. Sadly, a lot of wild ducks have an even bigger danger created by humans – the loss of their habitat.

There is no need to create any drama around Daisy. Right now she has out mustered all of the other birds and animals in the forest. As I said yesterday, an uneventful day is a good day for Daisy – just like it is for us!

The sun paints a rose-gold hue over the nest as it rises over the forest.

Our little duck uses this quiet time to do some aerating of the nest and some preening.

Look at that beautiful down nest lining! Wow.

The only visitors so far have been the Rainbow Lorikeets and they have spent their time on the bowl of the big nest.

Daisy heard them but she could not see them at first. They were climbing around on the bottom of the big sea eagle nest. When she realized that they were the beautiful rainbow coloured parrots and that they would not bother her or her eggs, she relaxed.

Daisy relaxes when she sees the Rainbow Lorikeets.
The beautiful parrots are all curious about Daisy.

I have this thought that always comes to mind when I see the Rainbow Lorikeets climbing over the nest tree. They are not frightened and that must mean that the White Bellied Sea Eagles are not close! That is a very good thing. The Lorikeets are still climbing around on the nest. They have been there for more than an hour. Daisy can relax and enjoy a nice morning.

I am so happy that you have joined me today to find out what has been happening in the world of little Daisy. I will bring updates as I try to do everyday in about six hours. Stay tuned to find out if your favourite Black Pacific Duck had any more adventures today!

Thanks to WBSE Sea Eagle Cam, Birdlife Australia, and the Discovery Center for the cameras so I can take my screen shots.

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.
