This 'summer' say a proliferation of Wood-pidgeons in the area I live in.
While they may be nice to look at, being woken at 06.00 or so every morning by a nesting pair, in a tree less than 50' from you're open bedroom window is not my idea of fun. I think next year will see me starting a campaigne of genocide against the neighbourhood's feathered rats. Plus they taste great in a pie. Yummy.
