Hi Jon,

You asked: Has any paper been written about movements with CBC and Australasian 
Koel? Here is the some information from Canberra, from relevant text from my 
book: "Canberra Birds: A Report on the first 21 years of the Garden Bird 
Survey"  The same sort of information is available about all the species 
occurring here.
Common Koel Eudynamys scolopacea

This cuckoo has arrived here increasingly in recent years, 48 of the 71 records 
were in Years 18 to 21, including many with repeat observations and some of two 
birds. Records are overstated a bit as one noisy male can be widely recorded. 
Their call is loud, far-carrying and distinctive and observers seek them out 
when told they have been noted nearby, so many observations are from the bird 
heard calling. Maller & Jones (2001) in Brisbane found a temporal pattern to 
their calling which will impact on recording rate. Seasonal pattern is very 
clear, arrive in October, build to a December peak then decline, last observed 
in February. They seem to inhabit only the suburbs locally and are the only 
species recorded in the GBS not to be recorded in bush areas around Canberra 
(except twice, COG Atlas & 1999-2000 ABR). They are probably attracted by 
fruit, that is not available in woodlands. No breeding records - yet.

Channel-billed Cuckoo Scythrops novaehollandiae

The 5 records comprise 5 observations. All are from late October to early 
December, in Years 12, 18, 20 and 21 only, so it may be increasingly passing 
through on southwards migrations.
Rank: 169, A = 0.00010, F = 0.42%, W = 0.2, R = 0.010%, G = 1.00.
