Commuters on the London Underground are used to the noise of the system, from the rumble and squeal of the trains to the barrage of announcements. How pleasant then to be able to record a different kind of sound, the tweeting and chirruping of the birds in the trees around Ruislip Manor station as they went about their business this morning. The sparrow has all but vanished from many gardens but I think I saw a few today, together with the regular pigeons, magpies, blackbirds and one or two others I cannot identify. The singing was at a high volume, perhaps indicating that the annual competition for nest-space and mates is well under way.
Many trees were cut down when the station was rebuilt a couple of years ago, and others were heavily pruned, forcing both birds and squirrels who had frequented the station borders to move elsewhere. At least some of the birds are back - the squirrels have not yet reappeared.
