Blackcap new for the year

The first day of British Summer Time was a bit of a let down to start with, a cold north-westerly wind had me wishing I'd packed my gloves and the Canary Wharf tower was invisible in the mist; not too promising for migrants but my first Blackcap of the year was tacking in the scrub at Bow Creek although not showing; the only other evidence of passage was a calling Meadow Pipit overhead at the ecology park and it or another briefly perched in a Silver Birch at the basin along with a Linnet. Two Greylag Geese were at Bow Creek and another pair flew up the Thames mid-morning whilst 11 Canada Geese scattered throughout the site was a good count for March; other wildfowl included 53 Common Teal and 42 Tufted Duck. An adult female Peregrine was on the Millennium Dome and presumably the same bird was seen flying up-river shortly later, the only wader noted was a Common Sandpiper at Bow Creek; still no Little Ringed Plover or Sand Martin, but other observers have seen both species and the next few days should see them fall.
