Thanks Geoffrey, while I agree the begging certainly gets much louder when
the host RWB approaches with food, I hadn’t really appreciated the actual change
in sound – I’ll listen out for this next time I visit. Jack Holland

I
haven’t had a lot of experience with these, but I think the ‘reminder’ call, a
persistent monotonous ‘kleep’ (every few seconds) that I’ve heard at several
sites should be distinguished from the ‘begging’ call when a host approaches
with food. This is a more animated ‘keark-keark-keark’. Both kinds
of call have something in common with those of the young of other species
in comparable situations.

Jack,
The similarity of
calls between koel and wattlebird chicks is actually something I'm measuring.
Haven't analysed anything yet, but I'm happy to tell you the results once I do.
Just from my observations, it seems like koel fledglings are sometimes able to
change their calls a bit from more wattlebird-y to more friarbird-y. I've heard
several that I think sound very similar to a Noisy Friarbird
fledgling.
Cheers,
Virginia

Re: [canberrabirds] young Koel
The one I reported
from Rivett last week was still there at 7:30 this morning, it has become
increasingly bold and easy to find over the past 9 days, though always still
within 50 m of where I first found it.
Red Wattlebirds were
still close to it, though I didn’t actually see feeding take place.
Interestingly one of these was a fledgling, though calling quite softly compared
with the loud and quite advanced one in my GBS site which has fooled me many
times over the past week into thinking it may be a young Koel. I couldn’t
help wondering if the similarity of the calls is another factor causing the host
bird to feed it?
