I noticed TD has been missing.
On the university campus where I work there is a lake and they have just put a board up with all the species of waterfowl, apparently there are some Tufted Ducks, the Greylag and Pinkfooted geese can be a bit of a nuisance when they decide to go walk about, not being particular where they sit down for a rest, middle of the road, car park, anywhere they like really and of course they always leave their 'calling card', even if you don't see them you know where they've been.
