Little Corella and Sulphur-crested Cockatoo
Yesterday I came across a large group of Little Corellas on the sidewalk. In the midst of them was a Sulphur-crested Cockatoo. It was interesting to see the two birds up close, because from afar they look very similar. This video shows an interaction between the cockatoo and one of the corellas. You can also hear the corellas chatting to each other constantly.
These two corellas were cuddling up:
The crest of a Little Corella is white, and smaller than that of a Sulphur-crested Cockatoo:
Little Corellas have blue-grey feet, a blue patch of skin around the eye, and a pinkish patch of feathers between the eye and beak. The birds’ overall colouring makes them look rather cadaverous!
Common name: Little Corella
Scientific name: Cacatua sanguinea
Approximate length: 36-39 cm
Date spotted: 23 May 2020 (autumn)

Sulphur-crested Cockatoos at Bobbin Head
A group of Sulphur-crested Cockatoos gathered on the mud amidst the mangrove stalks at Bobbin Head:
It’s the first time I’ve been to Bobbin Head. I started with the Mangrove Boardwalk and also walked part of the Gibberagong Track, which follows on from the boardwalk. This is the sign at the start of the Mangrove Boardwalk:
The cockatoos had gathered next to this bridge at the start of the Mangrove Boardwalk:
From time to time the birds flew up into the surrounding trees to have a peaceful snack:
And a bit of mutual grooming:

Four Yellow-tailed Black Cockatoos come to visit
Today I arrived home from a long overseas trip. An hour or so after getting home, I was delighted to hear the haunting calls of a group of Yellow-tailed Black Cockatoos. They came to visit our Old Man Banksia tree, which is currently covered in dried seed pods. A tasty snack for a cockatoo!
I love the comfortable nibbling noises the birds make. Every now and then they chatter to each other too, as you can hear towards the end of this next video:
Yellow-tailed Black Cockatoos are large birds, quite a lot bigger than the more common white cockatoo. They have a dignified, graceful presence. It feels like a privilege to have them drop by. We planted the Old Man Banksia (Banksia serrata)a few years ago, with the goal of feeding the local bird life. It looks like our plan is working.
Two of the birds flew up into a Sydney Red Gum that towers over our house, for a quiet grooming session. It’s cute how attentive the groomer is, even returning to her job when she notices that her companion still has an intractable itch. When she stops for the second time, he reprimands her and she returns to the task yet again.
The bird with the pinkish-red ring around his eye is the male. The females have grey eye rings and a lighter-coloured bill. Here’s a still shot of the male, looking content after a good grooming from his mate:

The Sydney Red Gum (Angophora costata) is a beautiful tree. I took this shot of it a couple of weeks ago, when the rain was making interesting patterns on the bark:
