I find this reciprocal trend to be very interesting.

My observations of suburban Rufous Whislter have almost always been in association with mature eucalypts, essentially the woodland component that you allude to. In contrast, Golden Whistlers seem happy in a variety of exotic trees and larger shrubs. I suggest that factor number 3 may well have had an influence.

My sense is that Rufous Whistler numbers are declining even in suitable habitat. The COG woodland surveys would surely provide definitive information in this regard.

BTW is there any interest in repeating the Winter Bird exercise this year?
