Garden Predator

This morning I glanced out of the window to see rather a gory scene unfolding on the fence of our neighbour's garden. 

A large hawk had chosen this spot to devour a freshly caught mouse - and he/she certainly made a thorough job of it.  After ten minutes or so there was very little left.

After consulting the bird books and the online Audubon guide,  our conclusion is that it was a juvenile Cooper's Hawk bit other suggestions/knowledge always welcome!
