15/09 Thatcham Marsh LNR

Location: Thatcham Marsh LNR
Session: 15-Sep-2019 07:20 to 11:30hrs

Notes: . No sign of any pollution from the sewage works spill. Just the faint smell we get when down-wind of the SW. The pond weed in the stream looked heathy. Moorhen still there; the 1990s incident cleared the stream of all life. Effects might take a while to materialise though. Another Blackcap dominated session but fewer birds about as the season progresses. The 7+ years old male is probably one of the eldest for some time; not that easy to check currently. The Sedge and Reed Warbler are latish, we have had the latter in October before. Nice day.

Weather: sunny period, warming up, calm, breezy later.

Present: JL, IW, JHW

Nets: 228metres in three rides of 198m, 18m, 12m up from 08:00 to 11:00hrs

Lure (audio): misc. migrants, warblers, aquatic warbler, reed bunting intermittently
