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!
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.
