Collared Sparrowhawks & Pied currawongs

[Andrew Thelander <>]

Hi all

I see in The Birds of Prey of Australia: A Field Guide by Stephen Debus (OUPA, 
1998) page 90, he refers to the population explosion of Pied Currawongs in SE 
Australia as a potential threat to the Collared Sparrowhawk. Currawongs are "a 
predator and competitor capable of robbing and injuring adults and killing 
nestlings."  Stephen is an authority in this field and has a wealth of 
information. Currawongs have invaded Brisbane over the years and are nesting in 
the city. I have also recently found a Collared Sparrowhawk nest which has just 
been abandoned by the birds for reasons unknown.

Does anybody have any information about Currawong/raptor interactions? It seems 
the currawongs are here to stay in Brisbane.

Regards

Andrew
