Learning how to be a Yellow-tailed Black Cockatoo
Strolling along a path at Manly Dam, I came across a group of Yellow-tailed Black Cockatoos. It’s always a treat being with these birds. They’re the quiet giants of the cockatoos in south eastern Australia. They sit on Banksia trees or, in this case, Casuarinas, chewing the seeds and chuntering to each other. Occasionally, one of the birds floats up into the air and glides to another branch.
In the group were two juveniles, making that almost-constant crooning noise that characterises them. I think it’s partially a request for food, and partially a reminder to the adult birds of where the little ones have got too.
This youngster hasn’t quite figured out what to do with a Casuarina seed pod. He finds one on the ground, touches it to his beak, then drops it. Nearby, an adult shows him how it’s done:
A little later, the youngster has climbed into a tree. Instead of tackling those hard seed pods, though, he practices wielding his beak on the bark:

Mmm, Mountain Devil flowers make a nice change from those tough Banksia pods!

Black Cockatoo feeding a youngster
Every six months or so, a group of Yellow-tailed Black Cockatoos come to our Banksia for a feed. They come for a few days in a row, then move on to find another feeding area.
Sometimes they spend more time plucking and dropping than eating. Still, it always feels like such a privilege to have magnificent creatures like this just dropping by. I love the wild, screaming noise that they make. Some people call them the “squeaky door birds”:
The tree is a Banksia serrata, also known as Old Man Banksia.
On the birds’ second visit a day or so later, I filmed some interesting behaviour. One of the birds was making a continuous groaning noise. That’s not unusual, and I’ve wondered in the past if the bird is a youngster begging for food, or if it’s some kind of mating behaviour.
I think I have an answer! In this video, it looks like the male bird (he has a pink ring around his eye) is regurgitating food and then feeding it to the bird that’s making all the noise:
I added quite a lot of detail about these birds in a previous post: Those magnificent black cockatoos are back!
