Daisy lays another egg!

Daisy, the very brave Black Pacific Duck, returned to the nest of the White Bellied Sea Eagles (WBSE) at 5:19 am. Everyone believed that she had laid the last of her eggs yesterday and had returned today to incubate them. Not so! Despite being concerned and ever watchful for Dad to return, Daisy did, at 10:33:34 Australian time, lay egg number nine. This means that she has a nest of seven eggs. Remember, Dad ate one and it is presumed, but no one knows for positive, that Daisy laid an egg elsewhere in the forest the day she was frightened from the nest before she could lay her egg.

One of the things that I noticed today was that, in addition to turning in the nest often and breathing deeper, Daisy also stood up, lowered her neck, stuck out her breast and pushed down diagonally during her labour. You can see a still image of this action above. You can, if you look carefully, see the growing number of eggs in the nest cup, too. Once the egg was out, Daisy relaxed.

Once the egg is out, Daisy begins placing more down and enlarging and lowering the nest.

Notice the small amount of down that Daisy has pulled from her breast to line the nest cup. Over the course of the morning, she has increased the size of and deepened the nest cup by moving around and pushing with her paddle feet.

The amount of down and the depth of the nest have increased gradually during the day.

What has afforded Daisy all this time today? Remember that Dad WBSE ate one of Daisy’s eggs yesterday and then covered the eggs. I have been actually hoping that the egg gave him indigestion (do eagles get indigestion even?) and is off duck eggs! Observers on the ground say that he has joined Lady, his mate, at Goat Island. Goat Island is 12.2 km from the nest. Hopefully the sea eagles will stay there until mid-February away from the heat of the City. Wouldn’t that be fantastic? Normally, Dad will come and check on the nest and the rest of his territory during off-season. It is like he is on vacation! It is currently over 26 degrees C on the ground and, presumably, a little hotter in the nest.

However, Daisy has very good camouflage and if she continues to lower her nest, just imagine. She could cover herself with fluffy down and leaves and just maybe the WBSE wouldn’t see her at all.

Stay tuned for further developments tomorrow in the adventures of Dad and Daisy.

Isn’t she gorgeous?

‘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.

Dawn is Breaking and Dad is still guarding his nest

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.
