Subject: Re: Resend [Birding-Aus] Question about inter-marrying between
raptors
Hi Kurtis and Belinda,
While I agree with what Kurtis said about a female goshawk preying on a male
sparrowhawk strange things happen on occasion. Jack and Lindsay Cupper in
their book "Hawks in Focus" devote a chapter to Black-breasted Buzzards
raising Nankeen Kestrel chicks. Normally black-breasted Buzzards feed
Nankeen Kestrel chicks and adults to their own young and the Cuppers suggest
that the kestrel chicks were originally brought to the nest for food, they
further suggested that instead of eating the kestrels the buzzards succumbed
to the kestrels begging behaviour and proceded to raise them as their own
offspring. At one stage there were seven kestrels in the nest, I am not
clear if any were fully fledged. This is all suupported with photographs of
the kestrel chicks in the nest with a buzzard attending or feeding them.
The Cupper's book has been overshadowed by David Hollands' Book "Eagles,
Hawks and Falcons of Australia", I feel this is a great pity as I have found
the Cupper's book diffirent and in some ways more informative.

Belinda,
I would beleive there is more chance of a female Brown Goshawk preying on
Mr Sparrowhawk, then getting married to him.
