Ravens go cronk and crows caw. Also ravens have far more attitude, comes
with the size I guess.

Sizewise from big to small: ravens, rooks, crows, jackdaws.


Thanks. I'm very familiar with Jackdaws and love their blue beady-eye.
Your remaining corvid size scale is useful for comparison, but I
rarely see them side by side to make that kind of judgement. I've also
been told to look out for feathered or shaggy 'trousers' or bare beak,
but they *all* seem to have that! :~( Most frustrating.

Shaggy trousers and a bare beak (actually a patch of bare skin at the
base of the beak) is a description of a rook. They also go caw. Ravens
have more angular heads than the others.
