The recent East winds and warmer weather have brought plenty of spring migrants to southern Britain. Today at the London Wetland Centre a twitch was in full swing at the Peacock Tower, the object of the lovers’ attention being a Common Sandpiper peacefully browsing along the muddy shore, happily unaware of the excitement it was causing. The breeding Redshanks, too, stalked about the shallows probing for food; the Lapwings as always alert, chasing off Carrion Crows and anything else that might have been interpreted as threatening. Around the paths, three or four early Sand Martin arrivals wheel and swoop like the small brown swallows that they are; their nest-cliff is still empty.

Around the reserve, quite a few Brimstone and Small White butterflies, and an Orange Tip gave movement and colour. I heard the first Sedge Warbler of the year, and despite being right next to the willow bush from which a Cetti’s Warbler was giving out its explosively phrased song, I couldn’t see the songster. A Blackcap however could be glimpsed behind the Sheltered Lagoon, chattering its alarm call.  A Song Thrush sang at intervals, and a Dabchick gave its beautiful trill and some small squeaks from the Lagoon, in between spending a lot of time under water.

Back at home, a queen Wasp was nosing about some Ivy-Leaved Toadflax, and a red Mason Bee dug for earth in a seedbed, flying off with a little load for her nest.
