I wanted to check in with all of Daisy’s fans to let you know that she is such a brave little mother. From the last posting, you will know that Lady, the White-Bellied Sea Eagle who lays her eggs on this nest and who raises her little sea eagles, showed up this morning at 5:37:11. Previous to now, it was mostly ‘Dad’ that came to check on the nest. Once in awhile, Lady would join him. I was always worried about Lady. Dad is, well, older. Someone familiar with the nest told me that he is nineteen years old. And he is laid back. As long as the bird laying their eggs on his nest is not a threat to him, I don’t think he cares. But Lady is different. She takes on the mantel of really being the person in charge of the nest. And maybe she hasn’t been happy with the way that Dad has been unable to evict “the bird” whose eggs are on her nest! It also seems that until today, the sea eagles had not actually caught sight of the the culprit, the owner of the eggs. But this morning Lady saw Daisy. Lady’s arrival and Daisy’s urgent departure meant that they almost crossed feathers! It really was that close. And Lady was mad. She had her whole chest puffed up. Lady became frustrated because she could not pick up the eggs in her beak. And then she began to tear the down from the top of the nest. But, sea eagles do not like duck down! There is no way around it. It is a foreign material to them. They are used to sticks. Down has no weight and it sticks to the beaks. That simple fact stopped Lady from doing any more damage. She tossed the down and, in doing so, covered up the eggs so the Ravens and Currawongs wouldn’t see them. What a nice thing to do for our little duck!
This morning Daisy did not go into hiding. She is getting near to hatch and she has much more invested in the eggs. She did flybys around the nest quacking all the time. The sea eagles left and within twelve minutes, Daisy was back on the nest brooding her eggs. Within a few hours, she had moved all of the down back to the nest and positioned it to warm the eggs. Other than really strong gusts of wind and a few song birds come to visit, the day, until now, has been uneventful. It is nearly 2pm in Sydney.
If the sea eagles are at their roost on the Parramatta River, one or both of them will probably come again today to check on the nest. But the high gusts of wind might discourage them. We can only hope. Right now they are more of a nuisance that keeps Daisy for incubating her eggs but they do not appear to be destructive. Daisy is not a threat to them. If, however, they stayed for five or six hours and the eggs cooled off, this would be disaster. Or if they moved the covering, the other birds might come and try to break or eat the eggs. So, once again, it is much better for Daisy if the day is simply boring and uneventful.
The image below was in the earlier post. It is a picture of Daisy arriving back at her nest with her lovely down scattered all over the twigs and leaves.
This little duck is so marvellous. She goes about what needs to be done. It doesn’t take her long, using her bill, to rake the down that Lady has tossed all about, back on to her nest. In the image below Daisy is tucking it around the edges so none of the cold air gets in to chill the eggs.
Daisy is being tossed about and rocked in the wind and the old Ironbark tree is creaking.
Did you know that Daisy talks to her ducklings? She is constantly rolling the eggs and tucking in and the down and all the while she is clacking away at her little ducklings. She does not know if any of these eggs are viable but she carries on talking to them. Hers will be the first voice that they hear and the first face that they see. They will imprint on their mother, a Black Pacific Duck.
If all goes well, Daisy will jump from the seventy-five foot nest in the Sydney Olympic Park and her ducklings will follow. They will jump out, spreading their wings to slow their landing, and bounce like a puff ball on impact. They will straighten themselves and get behind their mom and follow her to water where they will forage for food.
I have mentioned the many obstacles that Daisy could face getting the ducklings to water. I understand that is about a kilometre to the nearest water. A very knowledgable friend of mine told me that she had seen ducks take their ducklings through parking lots and schools if need be to get them safely to a river where they will immediately be able to paddle about. Isn’t it marvellous? One day old and they can do everything for themselves. Daisy keeps them warm and safe at night. Amazing.
It is nearing 14:00 at the nest and there is a gentle rain. Daisy’s feathers are waterproof and the drops collect on the surface of the feathers. When Daisy preens she uses oil from an oil gland to coat and restore her feathers. In fact, you might have seen birds spending most of their time preening. Their feathers protect them from cold and heat but also allow them to fly and swim.
The rain stays on the surface. And, besides, Daisy is used to being wet – she’s a duck!
Besides the oil that helps to condition the feathers, the feathers overlap. Look at the image below. In addition, ducks have angled barbs on each side of the central shaft of the feather. Each barb has tiny, tiny little hooks help hold the feathers together. Someone told me that it is like velcro on each side. This means that Daisy is covered with a lightweight shell of feathers that protect her and also allow her to float in the water.
It is now approaching 14:45 on the nest and Daisy is showing no signs of leaving for a break. It is extremely gusty with occasional rain. While the rain does not hurt Daisy and it would roll off of eggs, I imagine that Daisy would much prefer to keep her eggs warm and dry. The wings might blow the feathery down clear from the nest and the nest cup might also get soaked if the showers increased in their intensity.
For now, our little duck seems just contented to let the nest rock and roll in the wind.
I want to thank Daisy’s increasing number of friends from around the world in joining us. It is wonderful to know that so many people who speak many different languages and live in varying different cultures, come together to watch the brooding of a little Pacific Black Duck who dared to make her nest in the tree belonging to the White-Bellied Sea Eagles.
We will look forward to having you with us tomorrow. It will be Day 17 of incubation! And so far, the little duck remains on the nest.
Thank you to the Sea Eagle cam, Birdlife Australia, and the Discovery Center for the cameras from which I took my screen images.
