I can't really say I dislike any bird. I suppose the Herring Gulls come close to birds that annoy me sometimes. We have 2 chicks on our chimmney and the adult tries to attack me the minute I walk outside. But I don't hate them for it, they are only protecting their young. Although like I'm going to be able to reach them all the way up there lol!
No I can't say I least like any bird...
