hi all,

I have two questions about WA cockatoos (for an upcoming trip):

1) there are western corellas and introduced long-billed corellas in Perth. Are 
there also introduced little corellas there?

2) how the heck do you tell a long-billed black cockatoo from a short-billed? I 
know the bill is (of course) different but from pictures it doesn't look like a 
really obvious length difference, so can you only tell them apart with really 
close views, or is there some basic difference in the way they act or look?

thanks :)
