Collared Sparrowhawks vs Pied Currawongs

["Philip Veerman" <>]

Some years ago Penny Olsen had (in captivity) a Collared Sparrowhawk that had 
lost an eye from an attack by a Pied Currawong. I don't actually know how that 
was known. Last week I saw an aerial interaction between these two species near 
my home in Canberra. Was not really clear who was the aggressor. Neither is 
nesting here at this time. I'd suggest that aggression between most raptors, 
currawongs, magpies, ravens is all pretty ordinary.
