Migrant shortage

A Reed Warbler (heard only) and an increase in Sand Martins (21+) were the only new arrivals at the London Wetland Centre today. No Swallow influx, Yellow Wag or Common Whitethroat yet. 1 Little Ringed Plover is still on the wader scrape along with 8 Redshank and wildfowl have more or less cleared out with only 32 Teal, 12 Shoveler, 13 Gadwall, 18 Pochard and 119 Tufted Duck remaining. Others seen include 2 Cetti's Warblers (photo), 9 Common Snipe and 1 Peregrine over.
