[Birding-Aus] Re-introduction of growd-dwelling native bird species to revegetated urban parkland

[Tim Dolby]

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

Hi Tim,

No I haven't, but have wondered about it for areas like along the Yarra where Wrens seem to have become quite patchy in where they are found now, despite continuous, but maybe unsuitable vegetation occurs.

If the habitat is suitable and unnatural predators such as domestic cats and
foxes are eliminated birds like White-browed Scrubwrens and Superb
Fairy-wrens would probably make their own way to the site. Most birds, even
poor fliers, can traverse areas of unsuitable habitat when migrating or
dispersing. This often occurs at night.

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My unpublished study on White-browed Scrub-wrens showed that in East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
