Ham Lands: buttercups
Ham Lands is a mass of yellow buttercups as well as white hawthorn and cow parsley; with three species of buttercup in the first meadow north of the Thames Young Mariners. Buttercup identification features are in a handy guide produced by the BSBI on Twitter below. During my walk I heard sedge warbler in the burnt out reed bed, many dunnocks and blackcaps and > 15 song thrush territories over the two sides of the Mariners; this fell short of the usual standard walk but was sufficient to confirm that this is still one of London's top sites for song thrush. A common tern was flying over the lagoon despite the water sports and a brief kestrel appearance over the grassland. Sadly only a few whitethroat and no hirundines were seen at the moment.
