Hi all,

 I was treated to some fantastic views of a Channel-billed Cuckoo at around a 
metre today at work as one was checking out a Pied Currawong nest outside a 
colleague's office window. I noticed the size and shape, along with the barring 
of the underparts and thought there was a slight superficial resemblance (apart 
from the beak) to a Pacific Baza.
 Given that  /Cuculus/ cuckoos have plumage resembling sparrowhawks in order to 
scare host species birds from nests, I wondered if the Channel-billed Cuckoo 
was doing something similar by mimicing a similarly-sized raptor. There's a 
good paper on the subject in  /Cuculus/ cuckoos here:
 Any thoughts?
