Daisy had no more than returned from her dabbling at 16:18:07 and settled in for a wee bit of a rest when the ravens sounded an alarm at 17:55:58. Daisy stretched her neck to listen.
In the image below, Daisy is alerted by the sound of the ravens approaching. Remember that the ravens often follow the White-Bellied sea eagles into the forest.
Daisy stretches her neck. The distance from the river roost of the sea eagles is only about 1.2 kilometres to the nest in the forest of the Sydney Olympic Park.
The sea eagles fly really fast and there is no time for Daisy to cover up her nest. She hurries off to the left of the nest tree tree. Daisy is just a blur in the image below.
You may remember that it has been raining and that the sea eagles have come to the nest sometimes tearing off the down. Lady made a mess the other day and Daisy took her time and moved all of the eiderdown back onto her nest. But this evening she did not have time to cover the eggs and it is cool in the forest, only around 21.8 degrees C.
You might also remember that wet down. Look how fluffy it is now. The temperature from Daisy’s body and the wind as well as the rain stopping have fluffed up the down again so it now has its insulating values back. This is so good!
The sea eagles are still mystified about the little nest holding seven eggs right in the centre of their big nest. Dad arrives and looks. He can see the eggs instantly but no Daisy! He stands and stares at them. What are these eggs doing in my nest? I sometimes giggle because it reminds me of a story that I my mother and grandmother read to me when I was little and, in turn, I read it to my children: Goldilocks and the Three Bears. Do you know that children’s story?
WBSE Dad moves cautiously towards the eggs.
Dad leans down to take a closer look. The only eggs that he has ever know are those of his eaglets that Lady lays. But these are not Lady’s eggs! but they are in my nest!
Again, ever so slowly he moves towards Daisy’s nest just staring into that beautiful nest cup.
And then he sticks his beak in! Oh, no. Is he going to try and roll out an egg to eat it like he did before?
In the same amount of time that Dad took to closely inspect those big white eggs, he raises his head and looks off the nest. Does he know that the owner of the eggs is watching him? does Dad think they are a threat? does Dad associate Daisy with these eggs, a little innocent Pacific Black Duck?
And then he looks down again. Each time Dad looks into the nest cup he rolls the eggs for Daisy! Thank you, Dad sea eagle.
The Dad raises his head and looks off in the other direction. You will remember that Daisy flew around the nest quacking the last time both sea eagles visited the nest. She was very frightened but also, as much as she was scared, she knew she needed to get back to her single focus, incubating her eggs.
The behaviour of the sea eagles towards the little duck’s nest is of great interest to anyone wanting to learn about bird behaviour. No one that I know of has had a close look at the interaction between the largest birds in Australia and a tiny little duck that doesn’t belong in the forest.
Dad simply is stumped. He stands for the longest time staring at the eggs. Then he rolls them one more time and turns around and gets back on a branch of the nest tree.
Dad stands on what is called the parent branch looking around. When Dad and Lady raise their little eaglets in this nest, this is the branch that they roost on to protect the little ones. It is also the first branch that the eaglets attempt to walk and fly to as they get ready for their fledge.
Is Dad looking for Daisy? is he looking for a bigger bird? He flies off the parent branch and back towards his roost on the Parramatta River at 18:06. His visit lasted four minutes. Doesn’t seem like he is too concerned, does it?
Daisy might have taken the opportunity to go and forage some more. She does not return to her eggs until 19:27, an hour and nineteen minutes after Dad has flown out of the forest.
Still she is ever so cautious. In fact, Dad could be lurking off camera hoping to catch her. She stops and looks this way and that.
The rain started between the time Dad left and Daisy returned. Her beautiful fluffy down is all wet again! Let’s hope that her eggs did not cool down too quickly. That would be just so sad for our brave little duck.
And then she stops and listens. Dad was on the nest remember for four minutes and Daisy takes four minutes to make certain that he is no longer a threat.
Daisy slowly lowers herself onto her wet nest to warm her eggs. Remember that eggs need to be held at 37.5 degrees to hatch.
The sun has set and the light on the soggy nest has changed. Daisy knows that the sea eagles will not be back again tonight. Except for BooBook Owl, Daisy can rest. And we know Boo is just curious about Daisy. He is not going to hurt her.
Indeed, I often wonder what the other animals in the forest are thinking when they see the sea eagles coming and going and Daisy returning to her eggs time after time. Daisy is afraid of them but not enough to keep her from brooding. Her hormones and instincts and her entire self are tied to the hatching of the eggs now. She is ‘hard wired’ for incubation.
Thank goodness. Daisy had a very quiet night. It is now just before dawn. Because the sea eagles could have spent the night at the river roost, Daisy is being very careful to listen for the vocalizations of the other birds. She can tell which ones mean the eagles are coming. Daisy has learned much about the forest.
It’s after 7:30 and the sea eagles have not shown up today. It is rainy. The area around where Daisy has her egg cup is soaked with water.
Daisy has a visitor. Can you see the little grey and white bird with the black mask and yellow beak peeking down to see Daisy? Look carefully in the top right corner. They are grey with a black head, an orange or yellow beak and yellow feet. There are white tips on the tail feathers.
It is a Noisy Miner. These birds are loud and create all kinds of havoc in the forest. They like to chase other birds away. They eat insects but are also opportunist especially in cities. They are called ‘honeyeaters’.
The Noisy Miner is a nuisance to Daisy because it can be so loud but it is not such a threat that I am aware of, certainly not like the Ravens and the Currawongs. I am not even sure the sea eagles are a threat anymore. It is really that they keep Daisy off the nest and away from her incubating duties and her eggs are exposed and could get too cool to hatch.
The golden glow of the morning is moving across the nest.
It is going to be a cool day for Daisy and her eggs. The morning temperature is 19.4 degrees C. It is not supposed to get higher than 20 C with rain again for today. It sure is a change from when it was 40 degrees C a few days ago. Then we were worried about the eggs getting too hot. Today we worry about exposure and cold.
Everyone send Daisy your positive energy. Our brave little duck sitting on the big sea eagle nest needs all of it. Daisy is grateful to all her friends who check in to see how she is doing. From around the world – from Canada and the United States, Mexico, Brazil to Australia, Singapore, Australia, Japan, China, Hong Kong, Poland, Denmark, Germany, and France – each of you has joined to wish Daisy good luck. Thank you!

Thank you also to the Sea Eagle cam, BirdLife Australia, and the Discovery Centre for the camera that provides the feed for me to take my scaps.
