The top of photo is an adult
Carrion Crow, the bottom photo is a juvenile
Rook - or is it?
The culmen shape and length look good for
Rook but surely if it was a
Rook (now into its 2nd calendar year) then you would expect to see the greyish-white starting to appear around the base of the bill (at least a little bit) instead of an all black bill the same as a
Carrion Crow. The rounded head and lack of noticeable peaked crown also points towards
Carrion Crow. So...if it's not a
Rook, then is it just an aberrant
Carrion Crow with a rather straight and pointy culmen?
