On my old commute I used to regularly see rabbits (why do baby rabbits insist on darting right in front of you?) and the odd deer, which was lovely. My commute now is down a main road on the way in, any wildlife I see is mainly roadkill. On the way home its more rural, so in the last two times i've seen pheasant, squirrels, lambs (aww!), cows and lots of birds.

Out on MTB day rides it is predominantly sheep, especially in the Lake District, and other farm animals, as well as swans, ducks and lots of other birds that I don't know the name of but are striking enough to point out. On nights rides I've come across and owl and a badger (and lots of other shining eyes belonging to who knows what).
