Barnes WWT - spring unsprung

There's been a decent arrival of migrants in the last few days in London (Sand Martin, Osprey, etc) so a visit to Barnes seemed on the cards to see what was in. Mix of birds more winter than summer. Supporting winter were c10 Wigeon, still good numbers of Shoveler (c100); Teal (80+) and Pochard (c40); 15+ Snipe, a Jack Snipe from Dulverton (for some reason Jack Snipe always seem easier to see here in early spring) and couple of Redwing. Running out for summer were a Cetti's in full song, lots of the resident birds singing and GSW drumming, but no Sand Martins or Chiffies. Also around big female Sprawk and Peregrine and Water Rail.
