Hi Peter,
Thanks for the info. Peter says "I'm not sure what sort of data you had
in mind McComus". I know something of your work background and
publication contribution to ornithology too. Maybe Peter has forgotten
or it creates some context to say that McComas Taylor was for several
years the main compiler of the COG Annual Bird Reports, the founder
co-ordinator of COG's Garden Bird Survey who significantly set up the
project into the success it has since become - later built on by me and
the driving source behind and the author of COG's Atlas project (and
book).
It is just my suggestion and maybe perception that McComas might be
thinking, in terms of data, of something comparable to the published
work on COG's survey of the style of:
Taylor, M. & Canberra Ornithologists Group 1992, Birds of the ACT: an
Atlas. Canberra Ornithologists Group and National Capital Planning
Authority, Canberra. and Veerman, P.A. 2003, 2006, Canberra Birds: A
Report on the first 21 years of the Garden Bird Survey (in which Taylor
gets many mentions for his contribution to the GBS).
I know that Melbourne does not have similar intensity of data but the
trends you describe are still quite instructive.

Subject: Yellow-tailed Black-Cockatoos in Collingwood
McComus Taylor asked whether there was any data on Yellow-tailed
Black-Cockatoos in Collingwood.
I'm not sure what sort of data you had in mind McComus, but this species
has been steadily increasing its winter usage of urban parks along the
Yarra Valley and elsewhere in Melbourne, and even in the CBD, over the
last decade or more. It is being recorded with increasing regularity and
in increasing numbers visiting pinus trees and other conifers across
Melbourne. I've seen them in the Fitzroy gardens on the edge of the CBD.
Some people have suggested that this is a response to the large areas of
forest burnt over recent years, but its occurrence in Melb predates the
fires. I suggest it is another example of an adaptable species occupying
a
vacant niche and increasing its population as a consequence, just like
the
Galah, Sulphur-crested Cockatoo, Long-billed Corella and Little Corella
the before it. I can now routinely see 6 species of cockatoo in my local
area (Heidelberg-Templestowe) in winter (Gang Gang is the other).
