To enter you need to take some photos of any birds you've spotted within a five minute walk of any Tube station.
There are three categories one for adults, one for under 18's and one for TfL and Royal Society for the Protection of Birds (RSPB) staff. Each category winner receives: An annual pass for 2 people to the RSPB reserves, a free family pass to the London Transport Museum, bird books, bird feeders and bird seeds.
The competition opens today and closes on the 31st May. Full details are on the Mind The Bird website.
Thanks to the fab Tube photographer version-3-point-one for giving me the heads up on this. Admittedly I don't look out for a lot of wildlife around Tube stations and most of the birds I see around the London Underground are pigeons.
Perhaps I ought to get Brian Pigeon kitted out with a little camera, as he's bound to know where all the cool birds hang out round stations.
