It's pretty common in Canberra, where I guess naturally the Easterns
would have inhabited the treeless valley-bottoms and the Crimons the
wooded hills and mountains and they would presumably have come into
contact long before Europeans arrived.
There are one or two mixed pairs around the suburb I live, but I never
have my camera with me when I see them!
