Ian Warden's excellent article in Friday's CT about Gang-gang
Cockatoos mentioned the difficulty in identifying juveniles - the
challenge she had was separating juvenile and adult females. A
neighbour of mine asked my advice, as she saw some at her place
yesterday and wanted to report them through the ALA portal - I have
promoted the survey in the Wamboin Whisper newsletter.
Attached is a scanned extract from HANZAB covering Gang-gang ID:
Higgins, PJ (ed.) 1999, Handbook of Australian, New Zealand
& Antarctic birds, vol. 4: parrots to Dollarbird, OUP,
Melbourne, pp. 94-5.
Here are the illustrations of the birds from the same source: http://www.drivehq.com/folder/p11517028.aspx
. The captions are:
1. adult male
2. adult female
3. juvenile male
4. juvenile female
5. first immature male
