Sea Eagles arrive and almost catch Daisy!

Before I start with today’s update on Daisy, our beautiful little duck living in the forest, I want to thank Daisy’s friends from Brazil, Poland, Mexico, Canada, Australia, the US, and China for checking on her. The whole world cares about a little duck trying to brood her eggs in a huge nest that belongs to the Australia’s largest sea eagle. We are on day 15 of brooding. I am beginning to believe that some of the seven eggs will turn into ducklings leaping to the forest floor. Everyone please send Daisy positive energy. She has had to deal with the sea eagles and the ravens, twice each, in twenty-four hours and now it is 40 degrees C with 98% humidity. In other words, it might feel like a sauna.

Daisy, you are so beautiful!

Every once in awhile, Daisy tucks in the down and uses her bill like a broom to shift the leaves and plant material closer to the nest so that she can use them to conceal her eggs when she goes foraging.

Daisy stretches her neck to collect more leaves.
Daisy uses her bill to pull the leaves over close to the nest.

Daisy gets every more busy moving leaves. She even gets up off the eggs to bring in some old down and more leaves. Then she begins to cover up her nest so that she can depart for a break.

Daisy begins to conceal the eggs.
Daisy works to make it look like their is no nest.

Daisy was slow and methodical in getting many more leaves up toward the nest cup. Now she is beginning to take some of the down and folding it over.

There were no alarming sounds in the forest and Daisy made a slow walk over to the left hand side of the big nest to fly off. Two things are interesting to me. If she is caught on the eggs by the WBSE who are literally landing on the big nest, she can fly off from her nest through the twigs on the left. Second, today Daisy spent a lot of time getting leaves over. Look how many there are! But she left them scattered and she did not cover the eggs completely with down (or that is how it appears from this angle). I wonder if this is because of the heat – the 40 degrees C scorching heat on the nest?

After having a couple of frights from the sea eagles, Daisy has been very smart to return to her nest about ten to fifteen minutes before sunset. Tonight, she arrives on the big sea eagle nest at 19:55:48. She does not immediately head to where her egg cup is concealed. She stops and listens.

Listening.

Daisy raises her neck up as far as it will go to listen. She has returned a little before sunset and the sea eagles could still come and check on the nest to see if anyone is there.

No alarming sounds so Daisy settles down to incubate her eggs. It is a good time of day to really see her beautiful plumage and the distinctive markings on her head. Did you know that she has about 12,000 feathers?

It is now Day 16 of Daisy’s incubation, 27 January 2020 in Sydney, Australia. This means that there remains 10-14 days til hatch!

Daisy did very well in the 40 degree C heat. It is already 22.8 degrees C on the nest at 4:45. But, there could be a little rain today in the forest where Daisy’s nest is. It will certainly be cooler. The weather report says it should not get hotter than 26. That, of course, means that the sea eagles might want to check on their nest since it is cooler! Let’s hope they just stay at Goat Island. There will be gusts up to 29 kph which means the old Ironbark Tree will really be creaking and swaying.

All is well at 5:15:00

At 5:37:07 Daisy hears someone coming! She puts her head down and then realizes she has to get off the big nest. There is no time to cover the eggs!

Daisy on alert.

It is Lady! And she has seen Daisy. You cannot see her in the picture below but she just got off the nest the second the WBSE landed.

Lady lands.

This is the first time that Lady has seen that there is a real live bird sitting on his nest. This is the first time that one of the sea eagles has swooped in fast enough to catch a glimpse of Daisy as she flies out. Lady is not happy! Someone is trying to take over her nest she thinks. She is puffing out her chest.

Lady looking around for Daisy.

The most interesting thing to me is that the Sea Eagles have not disturbed the eggs as of late. Remember, before she finished laying all her eggs, Dad removed one and ate it. He did not like the taste or he would have eaten all the eggs. And both him and Lady have been curious but not destructive to Daisy’s nest.

Lady stands guard on the parent branch.

Instead of destroying Daisy’s nest, Lady flies to the parent tree. She can hear Daisy quacking in the distance.

Lady watching.

At 6:00:28 Lady is joined by Dad. Since Daisy began laying her eggs, I have never worried about Dad, the WBSE. For some reason, he was very curious when he ate the first egg but he is ‘hard wired’ not to step on eggs in his nest because they might be his eaglets! Lady knows better. And she is fierce and would not want another female bird using her nest. It is hers.

In the image below, Lady is getting ready to jump off the parent branch and join Dad on the main nest.

Lady preparing to return to the nest area.
Lady is not happy.

Dad, sea eagle, just doesn’t seem to care as much as Lady. She is starting to look at that nest with eggs again.

What’s in this nest?

Dad goes up on the parent branch to keep watch. Daisy is quacking and flying around the forest. Daisy knows that this is the last half of her brooding and the eggs cannot get cold! Daisy must be afraid that the big sea eagles will tear up her nest.

In fact, Lady tries to do just that. She pulls out down and tries to grab an egg with her beak but the egg is too big. Relief for Daisy. For some reason, Lady does not try to destroy the eggs which she could do with her talons. But she starts to pull apart the down. She doesn’t like it. It feels funny and sticks to her beak. And she stops.

Lady does not like down in her beak.

Lady jumps up to the other parent branch and watches out for Daisy in the forest as she flies about. And then, she gives up. First Lady flies out of the forest and then Dad. They are both gone by 6:15:15. This terrifying event for Daisy has unfolded over a period of fifty-two minutes!

In the image below you can see the huge sea eagle flying into the forest from the nest tree. In a few minutes, Dad will join lady down on the Parramatta River for breakfast.

Wonder if Daisy will be scared and stay away for five or six hours? She must be quite shaken.

Lady flies into the forest.

Remember that Daisy didn’t have time to cover her eggs for protection. Well, when Lady was trying to demolish the nest, she tossed the down about covering up the eggs. How lucky for Daisy. Now the Ravens will not see them.

The sea eagles left the nest covered.

But wait! I cannot believe it. This is one brave little duck. I think she needs a big round of applause. Daisy only waits in the forest for twelve minutes. The sea eagles leave at 6:15 and she gets back on her eggs at 6:37. Tears of joy are pouring down my cheeks. The eggs will not get cold!

Daisy, you are the bravest little bird I have ever seen to stand up to the big sea eagles.

No doubt Daisy will be on her guard today. The sea eagles are not far away. Instead of being at Goat Island today, they will stay at their roost on the Parramatta River since it is cool.

Oh, my. I hope this is the last excitement Daisy has until sunset. That is when the sea eagles might return to check on their nest. Sometimes, you will remember that they come earlier in the afternoon. Each time Daisy has been away foraging.

Daisy returns to her nest.
Daisy listens.

Daisy has some nestorations to do but her eggs are safe and so is she. That is the important thing. Daisy looks so happy to be back on her nest. She has in a few minutes gathered up some of the down. Thank goodness Lady just really doesn’t like it. She didn’t make a big mess. Daisy can easily get her cozy nest repaired!

I will bring you an update tonight, in about nine hours. Thank you for checking in on Daisy, perhaps the bravest little duck in Sydney, Australia.

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


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.

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.

Daisy brooding her seven eggs on the WBSE nest.

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.

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.

Was it THE Standoff?

Daisy the Pacific Black Duck returned to incubate her eggs in the old Ironbark Tree at 7:46 pm. She had a really uneventful night on the nest.

The pattern has been for the WBSE ‘Dad’ to come either alone or with his mate, ‘Lady’, at dawn to check on the nest. Every morning Daisy has been alert and has been able to leave the nest quickly, sometimes even being able to cover up her eggs. Today was her fifth day of incubation.

The cameras have not yet switched to their daylight setting and Daisy is very alert to everything that is going on in the forest. If Dad sticks to his pattern, he will show up any time.

At 6:05:49, Daisy hears Dad landing on the branch that supports the camera tree. She has only a split second to get off her nest before the largest sea bird in Australia arrives!

The camera operator took the opportunity while Dad was still standing at the edge of the nest to zoom in on the eggs to see if any of them were broken. It appears that all six are intact. Daisy laid eight. Dad ate one and one was probably lost in the forest the day Dad chased her off of the tree before she could lay her egg. And that is only a guess. She had laid an egg each morning so there is no reason to presume that she did not that morning.

To me, one of the most interesting aspects is the way in which the little duck made the egg bowl or cup to hold her eggs. Using the down she took from her breast and simple plant material and leaves she has almost felted together a lovely nest, the envy in its colour selections of any interior designer.

Dad still remains confused. He knows ‘something is up’ but precisely what that is, he is unsure. This is his nest in his territory and there are eggs and some lightweight fluffy material that is new to him.

At first Dad simply messes with the down like he has done every morning. It seems to mystify him. But at 8:21:31, he sticks his beak into the nest cup and rolls out an egg. You can see that egg in the featured image at the beginning of this blog. Then he goes back up to the parent branch of the Ironbark Tree and stands guard.

WBSE Dad was just not happy when he could not catch the intruder in his nest.
Dad poked around the duck’s nest but did not break any eggs.
Dad was always on alert to see if anyone was going to come to the nest.

Dad monitors all of the activity in the forest. Each little thing that moves gets his attention. What became interesting was that the Pied Currawongs that bother him and Lady and also chase their young out of the forest before they are ready to fledge, sometimes, came around the tree. Just as Dad would have done if it was his eggs on the nest, he sounded an alarm, a honk, for them to leave. And they complied!

Dad guarded his nest and Daisy’s eggs against the Pied Currawong who might have eaten the eggs.

Dad left the nest to chase some small birds at 11:54 am. He has not returned. At that point, the eggs had been uncovered for six hours. It is now almost 3pm and the eggs have been uncovered for nine hours. One lucky thing for Daisy is that the sun shone directly onto the nest cup. Whether or not the egg that is showing (see below) that Dad rolled is too hot is unknown.

It is summer in Australia and the temperatures range from 25-29 or even 30 C. It is anyone’s guess if the eggs are viable or if they were even fertilized in the first place. Some birders on the ground did see a lone Black Pacific male duck swimming in the canal yesterday.

The big question is: Did the WBSE finally achieve their goal which was to scare away the intruder for good? Stay tuned!

The one egg that Dad rolled out of the nest is sitting in full sunlight.

Gusts and a creaking Ironbark Tree kept the curious away

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.

Notice how Daisy turns clockwise in the nest as she continues maintenance and rolling the eggs.
Daisy continues to take down from her breast adding it to the nest and turning clockwise.

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.

Daisy quickly leaves nest to gather up more plant material from the WBSE nest.

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.

Daisy continues to use her bill to bring in leaves and plant material close to the neck cup. She might be preparing to cover the eggs and leave for a quick morning foraging.

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!

Daisy remains, triumphant – so far!

Just to recap what happened on January 13 at the White Bellied Sea Eagle nest in the old Ironbark Tree, Sydney Olympic Park. Yesterday, Daisy the Duck arrives at the nest at 5:19 am. At 10:33, Daisy laid egg number 8. It was a very hot day in Sydney, rising above 26 degrees C. It was very hot on Daisy, a water fowl, when the sun was shining directly on her as she incubated her eggs. At 16:49 Dad returns from his sojourn to Goat Island unexpectedly. Daisy leaves the nest in a hurry and does not cover up her eggs. Dad poked around the eggs in the nest bowl but he did not eat another egg nor does it appear that he damaged any eggs. In fact, Dad was pretty careful around the eggs. Dad leaves at 19:16. Daisy returns to her nest at 20:24 and incubates her eggs all night without any problems from Dad. This is the first time that the Black Pacific Duck has stayed all night incubating her eggs.

As the sun begins to rise over Sydney, Australia, WBSE ‘Dad’ returns to the branch of the cam tree and sits there observing the nest.

Daisy does not immediately notice Dad’s arrival at 5:54. When she does, she scurries off the nest leaving the eggs uncovered!

Daisy has been busy removing down from her breast to further line the egg cup.

With everyone holding their breath afraid that Dad would go and disturb the eggs or chase after Daisy, we waited and watched. But Dad only observed. He flew off the cam tree branch at 6:13.

There are, of course, many questions and no one has an answer. No other bird has ever made a nest, to anyone’s knowledge, in the WBSE nest tree. There appears to be no literature. Black Pacific Ducks are opportunists and did, at one time, make their nest in a bear enclosure at the Sydney Zoo. As their numbers dwindled, the ducks moved to another location. In fact, often their nests are in marshy areas near water. Why this duck picked this sea eagle nest seventy-five feet off the ground is anyone’s guess. Now, though, people are wondering if the sea eagle will leave Daisy alone to raise her ducklings. She is no threat to him or his territory. Only time will tell. And no one has any idea what the WBSE ‘Lady’ would do if she found some other bird’s eggs in her nest!

She returns, somewhat cautiously, at 6:37. She slowly walks down from the branch and begins incubating the eggs again. Wet grasses on her bill show that she did, in fact, have some breakfast while she was away.

It is nearing 9 in the morning, 14 January in Sydney, Australia. So far, all is well on the nest. Updates later tonight.

The Continuing Saga of Dad and the Duck or ‘As the Nest Turns’

Just to bring those of you up to speed in case you haven’t read my earlier blog. In early December, a pair of Pacific Black Ducks investigated the nest of a pair of White-Bellied Sea Eagles (WBSE) in an old Ironwood Tree in the forest of the Sydney Olympic Park in Sydney, Australia. On 14 December, a nest cup was excavated in the centre of the sea eagle nest by the ducks. (Note: This is off-season for the sea eagles.). Six days later, ‘Dad’, the male partner of ‘Lady’, to whom the nest belongs, came to the nest for one of his periodic territory checks. The female aptly named ‘Daisy’ by Phyllis Robbins of the WBSE chat group laid her first egg in the nest cup on 5 January 2021.

On the morning of 11 January, Daisy arrives at the nest just after dawn. Before she could lay her egg, vocalizations from other birds in the forest alert her that the sea eagle is about. Indeed, Daisy might have been listening for the male sea eagle because he had come to the nest the previous day. That day she quickly covered the eggs and flew off the nest but stayed in proximity. Dad stayed for about half an hour before leaving and within a few minutes, Daisy returned to lay her sixth egg without interruption. This morning, however, Daisy had not laid her egg when the large sea bird appeared. She stood on the rim of the nest and quacked as Dad flew to the camera tree. She left so abruptly that she did not have time to cover her eggs but, it seems that Dad did not notice her physical presence on the nest or her quacking.

Dad surveyed his territory remaining on the tree that supports the camera for the live stream for about an hour. He might have thought that the bird laying the eggs would return without noticing him and he would find out who this mysterious bird is.

After about an hour and a half, Dad flew to the nest tree to see first hand what was happening. He had noticed the eggs the previous day by rummaging around in the leaves. He even tried to pick one up with his bill but to no avail.

Three of the six Black Pacific Duck Eggs

Today the eggs were clearly visible. Look carefully. Daisy has started removing down from her breast to line the nest. This physiological process is called zugunruhe.

Under normal circumstances, Daisy would arrive at dawn to lay her egg. She would do this every day until she finished laying all of the eggs for her clutch. This can vary between 8-13 eggs. After laying her egg, Daisy often remains on the nest for a period of about an hour before departing for the river to forage for the rest of the day. Once all of the eggs are laid, Daisy will begin full incubation, being relieved periodically by her mate. After twenty-eight days, the ducklings will hatch. Then, the following day (after 24 hours), they will take a giant leap of faith and jump off the rim of the nest, a distance of approximately fourteen metres, to the forest floor. Here they will follow their mother to the Parramatta River where they will immediately begin foraging for themselves.

Dad inspecting the Black Pacific Duck’s eggs

Today, Dad began to curiously inspect the nest with the eggs. For what seemed like an eternity, he would look at the eggs and then look around the immediate environment of the tree. It was actually like he was confused. At one point he tried to pick up one of the eggs but he couldn’t do it. It isn’t that they are heavy; the shape is just awkward for him to handle with his beak. He did not try to move the eggs with his giant talons nor did he attempt to break them. He did toss some of the down around. At one point, it even looked like he might start brooding the eggs. It was a very strange exchange because Dad’s hormones are not thinking about breeding or brooding. He is in the midst of moulting.

Dad trying to move one of the eggs

The entire morning was very suspenseful. Currawongs and Sulphur-Crested Cockatoos were screeching in the background and at one point, it was thought that Daisy even did a fly by.

And then the oddest thing happened. Very delicately, Dad covered up the eggs at 9:01 am.

Dad covered up the duck eggs so that no one could see them

If that wasn’t peculiar enough, Dad went up to one of the ‘parent branches’ on the nest tree and stood vigil. More than once, Dad flapped his wings to keep the Currawongs away! Take altogether, these three actions scream out that his intuition is to protect the eggs.

Dad stayed for more than an hour before departing. At the time of this writing, he has returned once again to the nest tree where he is keeping watch over his territory.

Stay tuned!
