Heh, I remember a pair of swans that used to live near the road up to the bird reserve that I used to help my mother do cleaning work at years ago, we nicknamed them Richard and Judy Turpin because they'd just stand in the middle of the road and refuse to budge, no matter how much you beeped the horn or revved the engine. So you'd have to wait until they'd cleared off to one side of the road and you could get past.
Beautiful birds though, and subject to an interesting amount of legality in the UK. Couldn't say why though, they just taste a bit like Turkey...so...erm...I've been told.
