inter-specific agression, Little Corella v Sulphur-crested Cockatoo

[Con Boekel <>]

I sometimes wonder whether Little Corellas will eventually displace 
Sulphur-crested Cockatoos.
At least some of the time they spend feeding in the same trees. 
Yesterday afternoon, while photographing the reddish-tinted 
Sulphur-crested Cockatoo I observed a Little Corella and a 
Sulphur-crested Cockatoo feeding on the same branch. The Little Corella 
moved towards the Sulphur-crested, lunged at it, causing the 
Sulphur-crested to fly away. The Little Corella then moved into the 
place formerly occupied by the Sulphur-crested Cockatoo.
