I'm a bit stuck as to where to put wildlife questions, so I'll try here this time.
Today I found a 9" diameter patch of tiny feathers plucked from a small bird, in our front garden. We do have a cat but she has never dealt with a bird by plucking it before. It looks like the work of a bird of prey. We have sparrow hawks but when I have seen them take small birds they fly off with them, rather than plucking them on the ground. Can anyone suggest what might have left the feathers
