This morning I witnessed one buzzard killing another. I thought it was then devouring the carcass - but after the murderer left I went to the site and the corpse was intact, although a number of downy feathers had been ripped out of the body. There was another buzzard in the vicinity at the time. I have been unable to find any explanation online, but my thoughts would be territorial or a juvenile not leaving the area. Could anyone shed any light on this please?
