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.
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!
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.
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.
Update: It was a very short foray for Daisy. She was gone only until 14:32 – so under an hour and a half. When she returned it looked like she was pretending like she had just landed on the nest. Like always, she looked around and walked very slowly before going over to her nest. What I find interesting is that she does not immediately move the leaves or open the down. It is always like she is simply waiting a little more being overly careful. Daisy is so cautious. What a good little mother!
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.
Thank you to the Sea Eagle cam, Birdlife Australia, and the Discovery Centre for the cameras that provided the images.
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.
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.
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.
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, 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 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.
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.
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 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 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.
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.
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.
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!
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.
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.
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.
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.
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!
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.
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.
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.
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.
Thank you to Sea Eagle Cam, BirdLife and the Discovery Center for the cameras from which I took my scaps.
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?
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 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.
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.
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 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.
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.
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!
Daisy the Black Pacific Duck didn’t have any problems during the night. She had foraged at dusk and returned and all was well.
What Daisy didn’t know is that both WBSE Dad and Lady spent the night at their Parramatta River roost. It is not farm from the Ironbark Tree nest. Some are thinking that they will try to arrive early and catch the bird that is using their nest and evict them.
Daisy begins to sense something is happening and by 6:42 she is quacking and has moved off the nest, still quacking, to a branch of the old Ironbark Tree.
She continues to quack loudly, protesting and defending her eggs, until 5:43:46 when she flies away. One second later, ‘Dad’ the WBSE arrives at the nest! ‘Lady’ arrives after Dad. Can you believe this? She flew away at the blink of an eye when Dad landed on the tree. I wonder if she went to forage or if she hid in the forest watching and waiting til it was safe for her to return.
Lady flings the down around the nest and pokes at the eggs several times. Unlike Dad who seemed more confused for the past four days, Lady appears to be quite upset. Dad sits on the ‘left parent branch’ of the tree observing Lady who seems not to like the down sticking to her talons. It doesn’t appear that any eggs were harmed but that might not be the case. Lady moves up to the tree with Dad occupying the one of the right parent branches.
At 5:57:28 the WBSE sing their ‘duet’ or morning song together on the nest. Not only is this a way to wake up the forest and greet the sun but it is also a territorial call. ‘This is our territory!’ The White Bellied Sea Eagles are the largest birds in the old forest and, as such, are the ‘King Pins’. Little birds tease them during the night but they are not to be messed with, not their nest. Remember: no other bird has laid their eggs in this nest, ever!
Lady leaves the Ironbark Tree first and then Dad follows. A second duet can be heard near by at 6:04. Then all is quiet. Off in the distance, the WBSE do a third ‘duet’ at 6:12. The WBSE are telling the birds in the forest that they are upset and something has violated their territory! Will Daisy return? Did Lady break any of the eggs? Will the eggs be viable with so many interruptions and the down removed?
At 6:45 a cautious Daisy the Duck returns to the nest undaunted by all of the scattered down. She is accompanied by two Noisy Miners who, at first glance, appear to be her defensive escort. Noisy Miners are members of the honeyeater family. They are a grey bird with a black head and white tips on their feathers. I would not call their song ‘a’ song. It is more like a screech. They are more like an irritant than anything that can harm Daisy. They often come to the Ironbark Tree when there are eaglets on the nest.
This is such a brave little duck! She has to have the very best hearing as she makes her successful escapes the second that one of the WBSEs come to the nest.
Daisy might have been awake all night with the loud creaks and swaying of the Ironbark Tree in the frequent gusts of high winds last night but not a single intruder was spotted. BooBook Owl stayed home. WBSE Dad didn’t venture out to check on the nest in the evening or this morning. It has been more than twenty-four hours since he has been about. Spotters on the ground say that he is off at Goat Island, some 12.2 km away, with Lady. And, so far, Raven has not made an appearance. It is nearly 7am, the tree is creaking gently and Daisy is quietly doing nest maintenance. If you squint your eye, the white in the down lining of the nest looks like little twinkle lights.
Sometimes Daisy will quickly get off the eggs to go and fetch more plant material somewhere else on the big WBSE nest that she can’t reach by extending her neck as far as it can.
When Daisy prepares to leave to forage for food, which she did last evening for about an hour, she tucks the down into the nest cup folding it over on the inside. She also uses her beak and stretching her neck she pulls leaves up close. This way she can cover the eggs while she is away. Of course, we have now seen times when Daisy is frightened off the nest by both the WBSE Dad and BooBook Owl but, normally, she takes the time to gently and quickly conceal those precious eggs.
I wonder if you have ever thought about the amount of energy it takes a duck to lay an egg? I certainly hadn’t until this year when I watched Bald Eagles have hard labours when laying an egg and then Daisy. Those eggs don’t just pop out easy!
Sibley says that a single egg can weigh as much as 12% of the bird’s body weight. For Daisy, remember that she layed an egg every day for nine days. That has to be exhausting! Specials with precocial young often lay more eggs because the mother does not have to feed them. Precocial young are more fully developed when they hatch. Their eyes are open and they are fully feathered. In the case of the Black Pacific Ducks they can walk and find their own food. Remember that the ducklings will jump off the nest and follow the parent to the water to forage for food. They will actually jump off the nest before they are fully capable of flying like their mother. Daisy will keep them warm at night for approximately two to three weeks. Altricial young require much more care. They are born without feathers and require their parents to feed them until they are capable of self-feeding. A good example of an Altricial young is a Tree Swallow.
It is now after 10 am and Daisy has had only one intruder. The Raven showed up about 8am. Daisy quickly reached over and clacked, like she did yesterday, and off it went! Hopefully Daisy will have a non-eventful day on the nest. Fingers crossed!
The feature image shows an Australian BooBook Owl sitting on the rim of the sea eagle nest where Daisy has her eggs. She flew off the nest as soon as Boo arrived.
Boobook Owls are the smallest owls in Australia measuring from 10.5 to 14 cm (27 to 36 inches) in length. Those of us watching the White-Bellied Sea Eagle (WBSE) nest in the old Ironbark Tree in the Sydney Olympic Park are very familiar with ‘Boo’. The BooBook eats insects and small vertebrates. They breed in late winter and early summer and have their nests in tree hollows. Little Boo is infamous for striking the adult WBSE when they perch on their nest at night and for flying at and hitting the juveniles in the nest. Once or twice this past nesting season, Boo inflicted injury on the eye of WBSE mom, Lady. Boo is a nuisance but not thought a tremendous threat to Daisy. The problem is when she is frightened and flies off of the nest leaving her eggs exposed. For all purposes, it appears that Daisy is like a single mom having to do the incubating and the defence. She is one tough little duck.
Daisy returns to her nest around 4:43 am, some three hours after Boo lands on the nest. She waddled slowly over to the nest, looking this way and that, making sure that there were no more intruders. She settled and began incubation as she could not feel any threats still around.
Daisy remained on the nest incubating her eggs until WBSE Dad comes to check on the nest at 5:39:25. This has to be one confused adult male sea eagle! There are eggs in HIS nest and he is trained not to step on eggs in case they might be his!
Daisy meanwhile made her quick escape just 25 seconds prior to the sea eagle landing.
Daisy could have been watching from a short distance because she returned to the nest as soon as Dad flew away at 6:30:29. This is one lucky duck!
Two visits. It is a wonder that Daisy settled back on her eggs at all. Everything is quiet until 8:44. A raven lands on a branch of the nest and then jumps down to the rim! An egg eating raven!
The Australian Raven grows to 46–53 centimetres long or 18-21 inches. They appear an iridescent purplish blue-green and black in their plumage. They are part of the passerine family that includes crows. And they love eggs! Indeed, they are a great robber of nests. They are opportunistic feeders living on both plant and animals as well as food waste.
Daisy’s first reaction to the raven was to press her body flat in the nest. She appeared very frightened at first. And then she stood her ground. She leaned forward off of the eggs slightly and clacked at the raven. And, guess what? It flew away!
In the image below you can see Daisy stretching her neck and laying flat on the nest, just off the eggs, clacking. The tail of the raven can be see just slightly above the bottom right hand corner as the bird departs!
Daisy has settled back on her eggs in hopes of a much more quiet day. Stay tuned! It is not even noon in Australia and no telling what is going to happen next in The Chronicles of Daisy the Duck.
