Channel-billed Cuckoo aggregations

["Stephen Ambrose" <>]

I also think they could be aggregations and squabbles at plentiful fruit sources.  We’ve observed this in our garden, neighbouring gardens and in the streetscape over the last couple of weeks, in particular, the first time we’ve noticed such noisy aggregations here. The greater Sydney area has had prolific flowering and fruiting of plants this summer, possibly in response to the mild temperatures and rainy conditions over the last few months. So, there’s plenty of food for all types of local fauna.

 

Kind regards,

I have seen them in PNG in quite large flocks along the Fly River, looking like they were getting ready to migrate back to Australia, but aggregations at fruit sources are also likely, indeed maybe both.

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?
