A quick Swift one then

Had a quick session over Rainham Marshes RSPB last night after work and things seemed  very quiet, well a part from the kids on motorbikes it was. Anyway, Common Sandpiper and 7 Turnstone which is quite a good record surprisingly for the site and a load of Swifts which I tried to photograph, not easy with my Sigma lens which isn't fast enough, so much so I want to get a new Cannon lens. So here are my best efforts.
