Identifying Rooks

Adult Rooks are easy to identify thanks to the bare, greyish-white skin around the base of their bill. The rest of their plumage is all black.

A juvenile Rook, however, is similar to a Carrion Crow as it doesn't develop the bare bill-base until its second calendar year. If you're not sure, look for the Rook's characteristic flat forehead, peaked crown, ruffled drooping belly feathers and feathered thighs.

Rooks also have a straighter, more pointed bill, unlike the Carrion Crow's thicker, blunter and more curved bill.
