Reservoir blogs - Brent

Last Saturday I was at Brent Reservoir (also known as The Welsh Harp) in North London listening to warblers and attempting to get some sound recordings. A Reed Warbler in more marginal habitat was singing from a hawthorn some distance from its neighbours in the Phragmites/Typha mix. Its song contained much more mimicry including Common Tern. Below is a sonogram of part of Garden Warbler's song. Visit the 'official' Brent Reservoir website at:
