They're Called Carrion Crows For A Reason.

For those of a squeamish persuasion look away now. 

I noticed a wood pigeon fatality with scattered feathers on the lawn near the boundary fence the other day. Its where we often see our Sparrowhawk sitting so assumed it was a strike it lost control of and wondered if it might return to collect but no...

A pair of Carrion Crows arrive.

Very adept at plucking feathers.

Nature in all its gory glory.
