Thanks all. Yes, so my seeing & thinking proceeded thus:  All birds I saw in 
flight had rounded tails, so that cuts out Torresian Crows. Then I thought 
Little Ravens plus ARs. Following where possible on foot or just waiting, I saw 
that the population contained juveniles, so if "ontogeny recapitulates 
phylogeny" extends into infancy, these young might have calls more similar to 
Torresian Crows & so the group might be an Australian Raven family. (Might the 
TC call be closest to the primordial / prototypal vocalisation ?)

Thanks for the emails confirming exactly the progress of my thinking! When I 
see birds that look "lighter" I think LRs + ARs ? -- but really I guess ARs 
with juvs.
