Yellow-crested Cockatoo
The Yellow-crested Cockatoo (Cacatua sulphurea, 小葵花鳳頭鸚鵡), which is an introduced species, has a white plumage with yellow or orange crest and can be seen in major parks and Mid-Levels on Hong Kong Island.
In fact a large flock of them can be seen on treetops along the Bowen Drive and Bowen Road, Mid-levels every early morning as they are flying from canopy to canopy making a very loud noise.
This Yellow-crested Cockatoo was seen in the Hong Kong Park a few days ago as it was sitting on a branch sun-bathing.
