Mega-rookery

Not the best quality photograph... but this is the biggest rookery I think I've ever seen (it's near junction 12 on the M4). There are well over 100 nests. Usually the rookeries are busiest and most visible at the end of February, but the cold winter has put them back by at least a month this year.

If you're interested in rooks at all then you should definitely read Mark Cocker's book Crow Country!
