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.

‘Nest Stand Off?’

Daisy the Black Pacific Duck

The continuing saga of Daisy the Black Pacific Duck and Dad the White-Bellied Sea Eagle played out over the early morning and afternoon of 12 January. Dad stayed near the nest during the night keeping watch from a branch on the cam tree when he was not snoozing.

At 5:25, Dad was on guard trying to catch the bird that was using his nest. Daisy appears at 5:27. They must have just missed one another! She checks out the nest, does some quacking, and goes up what is known as the parent branch on the WBSE nest. At 5:40:17, Daisy flies from the branch into the forest. At the same moment, Dad returns to the nest. My goodness, this little duck is awfully lucky or she has the best intuition about the forest alerts!

Daisy arrives at the nest to check things out. She might be able to sense the WBSE was there.
Daisy was alerted to the arrival of the WBSE. She is quacking and has climbed to the fork in the branch where she will depart.

According to all the people who have observed this nest over the years, no other bird has ever made a nest within the wide WBSE nest and laid eggs. Plenty of small birds come to visit, including an owl, but none have ever attempted to use it.

Within a blink of Daisy departing, Dad arrives back on the scene!

Today, Dad is hungry and he works harder to grab one of the eggs with his beak and then his talon.

Dad rummages through the nest, tossing the fluffy down. He sets his eye on one of the eggs. Tapping it with his beak, he makes a tiny dent. Working with a talon, Dad is successful in removing the egg from the nest cup. After eating the contents, Dad is very careful to clean up the shells dumping them over the side. Does he not want the owner of the nest alerted to his tampering? Daisy now has 5 eggs left in her clutch.

Dad departs the nest at 6:08. Meanwhile, Daisy is keeping close watch from the forest. She returns to the rim of the nest when she is absolutely sure that Dad is down at the Parramatta River and might not disturb her for awhile. She watches and listens from the rim of the nest over the forest. She is so alert. She raises her head many times just to check on the sounds. You can hear the Currawong in the background. Often they chase the WBSE. Then there are the Noisy Miners. Lorikeets can be heard in the distance. Daisy is alert to each and every sound! When she feels a little safer, she moves closer to the eggs. But, interestingly, she never goes near the nest. She remains ‘frozen’, not moving or making a sound for more than an hour.

Daisy moves towards the middle of the nest from the rim where she remains frozen, not making a sound.

Daisy is very quiet so as not to draw any attention to her movements. She has waited as long as she can to lay her seventh egg. At 9:07 she sits in the nest. At 9:32:28, Daisy lays her egg.

During her labour, Daisy rotates in the nest, enlarging it with her paddle feet. At the same time she is breathing a little heavier and her tail is moving up and down slightly as she gently arches her back, at times.

On all other previous days, Daisy had stayed on the nest for about an hour to an hour and a half after laying her egg, leaving to go and forage at the river. Today, Daisy does not leave. It appears that she is in hard incubation.

It is nearing 2:30 in the afternoon Sydney time. Daisy remains on her eggs. Only time will tell what Dad will do if and when he returns. Stay tuned!

UPDATE: Daisy has been incubating the eggs for seven hours now. It is 26 degrees C in Sydney and hotter in the sun on the nest. Daisy is panting from the heat. So far, no sign of the WBSEs.

At 4:30, Daisy covers the eggs and flies from the nest.

The suspense is killing me! Back tomorrow with the latest.
