Identification of this bird would be appreciated. I think there are two and their mournful calling was recorded predawn at Allambie Heights NSW (lower and closer to Manly Dam). It calls from around 5.45am until after dawn, when it is outdone by the noisy neighbours. Many thanks in advance. Sue

Maybe a currawong? Not really sure though.
Yes, definitely a currawong
