Black-faced Cuckoo-shrikes as migrants

["alan morris" <>]

Hi Birders,

I remember in the late 1960s that John Disney, then Curator of Birds at the 
Australian Museum, collected a number of BFCS during some winter banding 
operations to show that by measurement and plumage, some of the birds in the 
Sydney area, were from Tasmania. While BFCS are common throughout the year 
on the Central Coast, in winter there a  number of flocks of from 12-26 
birds that seem to locate in the same area every day and I have often 
speculated as whether these birds were part of the Tasmanian population.
