Glossy Black Cockatoo versus Red-tailed Black Cockatoo at Burren Junction

["alan morris" <>]

Hi Birders,

I am not necessarily convinced that the black cockatoos seen by Bruce Roubin 
between Wee Waa and Burren Junction on 1 October 2006 were in fact Glossy 
Black Cockatoos. This is because Red-tailed Black Cockatoos occur between 
Burren Junction and Walgett , although mostly at the Walgett end. So either 
species could be present.
Therefore it should not be a question of location,  rather, the 
identification should be based upon the description of the birds sighted and 
what they were doing.  Glossies feed in the casuarina trees while in that 
area, Red-tails feed mainly on the ground. I wait to be convinced either 
way!
