Hi Peter,
Two things speak against Horsfield's Bronze-Cuckoo:
(1) size (compared to Superb Fairy-wren)
(2) barring (fledgling HBCs should be unbarred)
Cheers,
Nikolas

Subject: Size of juvenile Bronze-cuckoos
The other day I was walking past Mt St Joseph pond in Altona (Vic), and noticed
a tiny bird sitting on a branch. I had no binoculars, but at first I thought it
was a White-browed Scrubwren because it appeared to have some white markings on
its face. But it was very small, and just moved further up the branch when I
moved a bit closer.
Then a Superb Fairy-wren approached it, and I could see that their body sizes
were almost the same. I also thought I could see some partial barring on its
chest, suggesting Horsefield's Bronze-cuckoo, but the tiny size doesn't seem
right.
I assume it hadn't fledged yet, or it would have tried to fly away. Can anyone
tell me whether a young HBC could be fully feathered and climbing about in a
tree, yet still not much bigger than a SFW?
Incidentally, the pond is totally dry at the moment, apart from a tiny puddle
right under the outfall of the drain under the north platform.
