For what it's worth, I've seen brown gerygone before at BP, at the South
end of the lagoon where the bird hide is (opposite end from the hide)
near where the walking/cycling track dog legs.

I would imagine that they were most likely Brown Gerygone as they would
typically associate more than the Mangrove in larger groups and the
Mangrove is still quite rare to my knowledge in Sydney. I have seen a
small number of Mangrove Gerygone in the mangroves in Avalon in Sydney's
northern beaches a few years ago were they may still be resident.
Mangrove Gerygones may be increasing in the Sydney region but even where
they are more common in other parts of Australia (Newcastle in NSW,
Darwin etc) I have not seen more than 6 birds however other birdos may
have seen more together. Many of the Brown Gerygones presumably from
higher altitudes (like the Blue Mountains) or from further south can be
found in the lowlands within the Sydney region during the winter and
often in open woodland with a good under-story (the woodland/forest
around Prospect Reservoir on Sydney's Cumberland plain is one regular
wintering place for them).
Did you hear these Gerygones call? The calls between the two species are
very different. The Brown is a plain call resembling in words like "What
is it.. what is it" whereas the Mangrove makes a beautiful warbling call
similar in the lines of the White-throated Gerygone but slower (if you
know the call of that species).
Hope this helps
Edwin

Subject: [Birding-Aus] Gerygone Bi-Centennial Park
Hi all, Was in Bi-Centennial Park today and saw What i thought was a
fairly large group of Brown Gerygone. As far as i know one way Brown
Gerygone can be distinguished from Mangrove Gerygone by the fact the
brown's underparts go from white to buff at the rear,while Mangrove
has totally white underparts. One of the things bothering me about brown
gerygone is the habitat i found it in,right next to the mangroves( less
than 10m away) in some casuria.I only expected to see Brown Gerygone in
forest or thick bush gullies, both of which were absent and not it would
seem anywhere nearby.I would welcome anybody with local knowledge.
Thanks in advance and am looking forward to all your thoughts.
regards G.Crompton
