I was reminded yesterday that Daisy the Black Pacific Duck is not normally an inhabitant of the forest. She lives down by the water and would, at most other times, make her nest on the ground. She would shape grasses and other plant material into the egg cup or bowl. It is only once she has started hard incubation, that Daisy, like other ducks, will pluck the down from her breast and line the nest. She will continue to add plant material and down to the nest as needed, often replacing what others pull out and destroy.
This year, Daisy didn’t make her nest on the ground. Instead, her and her mate selected a very old nest in an Ironbark Tree in mid-December. That nest belongs to the White Bellied Sea Eagles whose territory is around the Parramatta River and the Sydney Olympic Park forest.
Daisy would have had many intruders if her nest were on the ground. But she would have been familiar with them and they with her. Because she is brooding her eggs in the forest, she is a curiosity. The birds and animals that live there do not know about ducks. They do know that it is the sea eagles that raise their young in this particular nest. Of the curious, one of the first was the the Pied Currawong who, unable to eat the exposed duck egg, threw a little mini-tantrum pulling out much down from the rim of the nest and tossing it over the rim of the sea eagle nest. Others who have come to the nest to check out Daisy have been the BooBook Owl, possums, Ravens, and Sulphur-Crested Cockatoos.
Today, the Rainbow Lorikeets returned. They are the most colourful parrots in the forest! They are ever so curious about the duck in the sea eagle nest! Oh, not just six or seven, but dozens of them! And Daisy was not sure she liked them getting close to her and her precious eggs. Rainbow Lorikeets are a medium sized parrot that are plentiful along the east coast and southern part of Australia. Unlike Daisy who has a bill, they have a beak. They are nectar feeders and are no threat to Daisy. But she doesn’t know that! And like any mother, she will protect her nest and her young as best she can.
At first, it was only three (one out of the picture frame). They were a little cheeky and one of them, totally curious as to why a bird they had never seen should be in the eagles nest, crept over close to Daisy. Daisy turned around in her nest and away from the pleasant morning she had been having and ruffled her feathers and readied to defend herself against birds that she had never seen also. She did not know if they were looking for insects in the nest or if they would harm her.
One of the rangers that researches the nest of the WBSE said that the Rainbow Lorikeet were there to give Daisy the Duck a lecture about not making a nest in a nest owned by sea eagles. But, alas, it is too late if that is what they are doing. Daisy is now on day 7 of incubation duties. She is devoted to her duties!
After all of the commotion – and it really was a boisterous affair – with the Rainbow Lorikeets everywhere, Daisy settled into a little bit of nest renovation. Remember the Curra and Dad the Sea Eagle had moved down off of the nest. Look at how far Daisy can stretch her neck. I had no idea looking at her that her neck could get so long. She also used her bill to help gather up some down and plant material that had scattered.
A bill of a beak? Ducks have bills. They are very lightweight. The exterior coating over the interior spongy bone is made out of the same material as our fingernails, keratin. And just like our fingernails, the keratin covering is always growing, healing over dents and scratches, but also maintaining its shape after much use. Ducks do not have to go to a nail salon for a trim!
After nest renovations, Daisy takes some time to do some preening. Daisy’s feathers are very important to her. She is a ‘diving duck’. That means that she submerges under the water to find food. For ducks like Daisy, it is essential that their feathers be in prime condition. Many types of birds spend up to seventy percent of their time preening, conditioning their feathers. Daisy’s beautiful feathers have grown very tightly. The feathers are stiff and are quite strong compared to the down. In fact, people used to use the feathers as quills to use with ink for writing. Daisy’s feathers grow close together and overlap one another. Look closely and you can see this. They make many layers that are weather resistant and protect our duck.
It is nearly 11am in the world of Daisy. Dad the Sea Eagle did not show up at dawn to try and catch the intruder using his nest. Daisy has decided to try and rest a bit. She is still very alert.
Will Daisy take time in the heat of the Australian summer to go and forage? Will she voluntarily leave covering her nest? Will Dad come at dusk? We wait.
