“I was on my regular birding around my house at Clementi Avenue 4. When I walked on the old railway track along Pandan River jogging path behind Faber Crest Condominium, I saw these parrots on the ground in group. There were about eight of them but I can only capture five birds in this picture. This is the first time I saw parrots gathering on the ground and I guess you might be interested to know too.”
These can be the Yellow-crested Cockatoo (Cacatua sulphurea), an escapee in Singapore seen as far back as the early 1900s. By 1970 a resident population has established, breeding in the Central Catchment forest. Now, noisy flocks can be seen at various locations. This white parrot is easily recognized from its prominent up-curved yellow crest. The bird feeds mainly in trees but do go to the ground to feed when necessary.
On the other hand they look suspiciously like the Sulphur-crested Cockatoo (Cacatua galerita). This is an uncommon escapee.
Can someone confirm?
