Just reading through the August gang-gang newsletter and Jack Holland’s column
(which is always excellent). Jack mentions observations by Jenny Bounds and
himself regarding increased numbers of bowerbirds in winter. There was a brief
exchange about this on this chatline on 18 August last year, with observations
from Jean Casburn, Paul Gatenby, Tony Lawson, and myself.
When I’ve talked about this phenomenon, I like to mention the data from the
original breeding bird study completed by Stephen Marchant at Moruya. On a ten
hectare block of forest there was one territory occupied by a blue male.
Stephen made an effort to band all bowerbirds one winter, ending up with 187
birds banded. That’s a huge number of birds passing through. The vast majority
of those were never encountered again.
