Yellow-tailed Black Cockatoos in inner city Sydney, NSW

["Philip Veerman" <>]

The data shows they have increased dramatically in abundance in Canberra over 
the years, too (along with all the resident parrots that are larger than the 
Eastern Rosella). The rate of this increase process, increased in 2003, post 
fires, when we had flocks, typically of 10 to 20, but sometimes of over a 
hundred of them, within the outer suburbs (I myself had one group of 
approximately 350 of them at my work GBS site near the Canberra Airport). This 
does not mean their population in total has increased (although it might have). 
It could be that conditions forced them into the city (along with that they 
seem to have increasingly adapted to feeding on pine cones).
