The Brown Treecreepers into a woodland remnant near Canberra comment is
relevant but they are quite different situation from Superb Fairy-wren and
White-browed Scrubwren. Or maybe I am just thinking of Canberra, where the
latter two species are still so common and dispersive, that they re
establish themselves constantly, just through normal dispersal. (Hard to
suggest a need for such a program here for those species.) Sure due to the
numbers of Pied Currawongs and cats, (and possibly Collared Sparrowhawks),
urban areas may be a bit of a population sink for them. In contrast, the
Brown Treecreepers has declined from formerly reasonably widespread to very
few colonies, that are very isolated. We do not have Brown Treecreepers just
passing through Canberra suburban habitat but the other two species
constantly do and breed successfully in suburban gardens and parks (I have
had both species at least once successfully raising young in my very
ordinary little suburban garden).
