A slow trawl along the droves west of Cheddar Reservoir produced a number of common warblers and a couple of Lesser Whitethroats.  Down by the Cheddar Yeo a Kestrel was chased by a single Swallow.  A Sparrowhawk flew in and out of the trees by the Sewage Works and a Kingfisher was glimpsed briefly as I crossed the stream near the Pumping Station.
