Grey Currawong

Interesting. We get two curawongs (one of which is endemic) and one raven. At least the raven is easy to identify. ;)

Yes, the bills are different, but again locally, I expect the blacks to have a more prominent hook on the tip of the bill, as well as having a generally heavier one. But your grey has a very noticeable hook. Do you get a pied curawong where you live (Tasmania lacks one)?

Yep, that's them Steven. Only, here they really are black. Apparently they are lightest in the western most part of their range, and get darker as they move east. Here's the best I've managed to get of the grey: http://www.projectnoah.org/spottings/4706016 And here's the black (note the black under-tail coverts): http://www.projectnoah.org/spottings/2823001
