Channel-billed Cuckoo aggregations

["Penny Brockman" <>]

More likely just an activity prior to moving north in the safety of flocks as people have noted in the past. Adults would know the good stop off points with fruiting trees.  

I once had an adult with a very young  juvenile in my back garden. Looked like parent collecting fostered child.  Time to show it what it really is. !!

Probably a bit early in the season (usually March/April) but I suspect they congregate like this to 'teach' the young how to migrate north, as their host parents, Torresian Crows/Magpies/Currawongs are probably residents (certainly not long-distance migrants)

What do others think?

G’day

My most common CBC observation is a single bird calling in flight, with numerous instances of coordinated duos. 

A while back I came across a group of 4 hanging out in a eucalypt and I was struck by their similarity with hornbills.

This morning I saw a combination of 7 CBCs (6 in a bunch an another flying to join them). My question, is why would such a large group come together?  I can understand a pair doing a nest raid, and two pairs facing off over territory, but why would 7 come together?
