Before I bring all of you up to date on our cute little duck, Daisy, Daisy wants to thank everyone from Canada, the US, Australia, and all the people from Poland who are concerned about her and come to check on how her day has been going. The last 20 hours have been anxious ones for Daisy.
Zanim opowiem wam wszystkim o naszej uroczej małej kaczce, Daisy, Daisy chce podziękować wszystkim z Kanady, Stanów Zjednoczonych, Australii i wszystkim ludziom z Polski, którzy się o nią martwią i przyjeżdżają sprawdzić, jak minął jej dzień. jechałem. Ostatnie 20 godzin było niespokojnych dla Daisy.
It had been so hot on the nest, with the temperature rising to 36 C, that Daisy took another break, yesterday, at 16:14:38. It had only been four hours since she returned from her last break. The heat is very hard on Daisy. She has lost so much weight and her stores of calcium creating eggs, laying them, and now brooding. And unlike other mated pairs of birds, she has no one to bring her food to the nest or to relieve her. Daisy is all alone. There is no one to even protect her from predators except herself. And the predators are lurking about today.
While Daisy is away dabbling, one of the White Bellied Sea Eagles flies in to check on the nest.
WBSE ‘Dad’ looked out all over his territory and waited by the nest right at dusk to see if anyone was there. But no one! You don’t see anyone on the White Bellied Sea Eagle nest, do you?
Daisy returned to the nest at 20:15:36. Our little duck might not be a permanent resident of the forest but she has learned how to listen and tell when the big eagles are about. She waited until she was certain that Dad would not be returning. They missed one another by eleven minutes!
The sun had completely gone down by the time Daisy returned to her nest. Don’t ever let anyone tell you that ducks are not smart. So far she has used all of the powers that she has to keep her and her eggs safe. And we have also learned something. Daisy has much better night vision that the sea eagles. In the image above she is carefully returning to her nest. She does not want to drawn any attention to where her eggs are.
There are no visitors to Daisy’s nest during the night. She is awake many times preening or turning her eggs. The sun will be coming up in about half an hour.
It is going to be 40 degrees in Homebush Bay, Australia where the duck nest in the Ironbark Tree is located. I wonder if Daisy will go out to forage and cool down before dawn?
Daisy decided against going out to forage. But at 5:50 am, she raises her neck. She has heard something!
Daisy has a split second to get off her eggs before the Sea Eagle lands on the nest! In the image below you can see her flying directly off the eggs to get out of the way of danger.
Daisy had no time to cover up her eggs. The White Bellied Sea Eagle lands just as Daisy clears the big branch. It is 5:50 am.
The White Bellied Sea Eagle walks over to check on the nest and look around.
In a few minutes the second White Bellied Sea Eagle comes to the nest in the old Ironbark Tree. In unison, they both look down at the eggs.
For some time, the sea eagles have appeared utterly confused by what is happening in their nest. Who has laid these eggs? Where are they? Who are they?
I often wonder if they think it is a bigger bird trying to take over their territory. There is, of course, no concern that a tiny little duck would want to do that.
Both of the sea eagles look like they are talking to themselves. One of my friends thinks that this could be a very funny conversation between Dad and Lady with Dad trying to explain to Lady that he has nothing to do with these eggs.
Once again, the White Bellied Sea Eagles do not disturb the nest. They are curious about the intruder into their territory but they do not appear to be hostile to the eggs. It is all quite interesting.
For a few minutes both of them are on one of the branches of the big Ironbark Tree. You can barely make out one on the branch that cuts through the middle of the right hand side of the image.
At 5:57 the sea eagles do the second of what is known as the ‘duet’. It is a morning greeting for the sun. At the same time it is also a sound they make when they are defending their territory. It is a series of honks.
Lady leaves at 6:11 but Dad stays on the branch for at least another hour. Meanwhile, Daisy eggs are exposed. It is 21.8 degrees C.
Daisy returns at 7:50:11 and once again is very careful when she gets on her nest. She has no more than relaxed and she begins to hear a commotion in the forest coming towards the nest tree. She raises her head to listen carefully.
Daisy listens very careful. It is the Ravens. The Unkindness comes to the tree at 7:58:06. They are cawing and Daisy is afraid. She fans out her feathers to not only make herself look larger than she is but also to protect her nest. Just like raptors protect their food, mantling.
The ravens leave after about ten minutes returning in half an hour to harass Daisy again. They want her to get off her eggs so they can eat them! Daisy remains still turning in the nest so that she can always see where the ravens are.
Whew! In the period of two and a half hours, Daisy has been frightened off her nest by the WBSE and has had two visits by the Ravens. It is getting hotter and hotter for our little duck. She is going to have to come and go often today if she is to stay cool. The humidity is 98% and the temperature is climbing steadily up to 40. Right now the nest is in the shade. It is nearly 11 am and maybe Daisy will now have a quiet day. The Ravens and the WBSE should be trying to find a spot to stay cool for the day.
I have checked with a person who knows about eggs. The Ironbark Tree is a very deep and wide tree. It actually holds the heat. Daisy’s nest is right in the middle. Even though she did not get to cover her nest and despite the fact that it was only 21 or 22 degrees C then, it is thought that the down and the warmth from the WBSE nest would have kept the eggs sufficiently warm. This is Day 15 of incubation. Let us hope so! The individual that told me about the temperature said that they were worried if the eggs got too hot from being exposed to direct sunlight. We learn something every day!
Thank you for joining Daisy. She hopes to have a nice quiet albeit hot day in the Sydney Olympic Park forest. I will provide an update if anything should happen in about six or seven hours. Otherwise Daisy and I will see you tomorrow. Good night. Stay safe!
Thank you to Sea Eagle cam, Birdlife Australia, and the Discovery Centre for the cameras where I took my scaps.
