Mercer CP - Black-throated Diver

Just outside the M25 but inside the LNHS recording area, Mercer CP couldn't have felt more suburban.  A boating lake with not much wildfowl present, the juvenile Black-throated Diver was always distant as it coursed its way round the lake.

Also noted was a Kingfisher along the periphery, a Chiffchaff, small groups of Redwing and a Treecreeper within the woodland.
