G'day Tim and all
My unpublished study on White-browed Scrub-wrens showed that in East
Melbourne they mostly used Blackberries for protection and food
production. They spent 2nd most time in Goodenia. While we were
planting out natives in Wurundjeri Walk, I asked Council to not clear
the blackberries until the native plants had regenerated enough.
They held off for 5 years then sprayed the blackberries while the
Superb Fairy-wrens were nesting in them. I returned from PNG to see
this predicament just before the Fairy-wrens and Scrub-wrens died out.
The natives have now grown but are still a bit patchy for small
birds, and occasionally I see Scrub-wrens, (they are able to live in
and move through peoples yards) but neither species has taken hold
again. Brown Thornbills which were not here before have taken over -
but cats and foxes are a problem to any bird that spend much of their
time low to the ground. The aggressive native birds have increased
and they can also be a problem.
I guess the message is get the "bush thick and continuous" and see if
the birds bring themselves back, if not they try re-introduction
after the cats and foxes have been dealt with.
Cheers
Mike

Hi all,
I 'm wondering if anyone is aware of any instances i.e. if there is
any precedent for the re-introduction of native bird species to
isolated revegetated native urban parkland?
In particularly I'm thinking about the reintroducing of ground-
dwelling species such as Superb Fairy-wren and White-browed
Scrubwren which, unlike arboreal species, are unable to migrate
into revegetated parkland due to the lack of an existing native
corridor - specifically when the revegetation process involves
developing complex native shrubslands, perfect habitat for these
species.
Cheers,
Tim Dolby
