Is there a list anywhere of the fewest number of times a species has nested in UK...? was talking to wife about bee eaters breeding near here a few years ago and said it very rarely happens and when she asked if there was any species that had only bred in UK once, I had to admit "I don't know"...I mentioned Great White Egret as a possibility but she says that wouldn't be what she meant if it was going to start breeding regularly..she meant "one-offs" .....can anybody help?
