In case anyone else is interested, Naomi Langmore (BoZo Bronze-cuckoo
researcher) says that when juvenile Horsfield's B-Cs get old enough
to leave their hosts they often associate and form flocks. It is
possible that the one I saw was just hanging out with "big
kids". That is, the association may be social but not family. I'll
live with that unless any conflicting info turns up.

I saw today (Barron Woodland) an adult Horsfield's Bronze-cuckoo
consorting with what appeared to be a juvenile. To me this is
surprising so I wanted to ask the old hands (and owners of HANZAB)
if this is normal and how the cuckoo life-cycle proceeds. I
thought a cuckoo laid her egg and then departed to fun and freedom,
leaving it up to the hosts to do the nurturing. If so, how/why does
an adult cuckoo end up travelling around with a young bird? Do they
actually hang around and wait for their offspring to fledge and then
join up again? Or...?
