This thread struck a chord with me, because I've got a sort of 'mild' obsession with surnames and their meanings, and I've been particularly struck by how many of them are birds.
Off the top of my head I can recall knowing or knowing of people with names like Sparrow, Crow, Raven, Pigeon, Eagle, Partridge, Duck, Parrot, Finch, Hawk, Goose, Gosling, Swan, Heron, Wren, Kite, Nightingale, Buzzard, Gull, and a few more. Oh, and Bird of course!
I wonder why this is?
