I thought the various sizes of identical looking birds in the garden were crows. They have a lighter patch on the back of the neck.
However, there are now some really, really big black birds with big black beaks which I think are ravens, no lighter patches, beautiful birds and they bounce along sideways.
(There are also blackbirds which I know are not Corvids (thrush family) and I know they are really blackbirds).
I have looked them up but it seems I am not alone in this failure to identify correctly.
Assuming the big ones are ravens, can someone help with the crows or are they rooks or what?
