12/05 Thatcham Marsh LNR

Location: Thatcham Marsh LNR CES visit 2

Session: 12-May-2019 06:00 to 11:00hrs

Notes: On this visit we had a good selection of species. It seems that there are more Blackcaps breeding in the scrub along the stream. Some older recoveries included: a 2014 Cetti’s Warbler, a 2013 Dunnock, a 2015 Robin and a 2016 Wren. We captured the first juvenile, a Long-tailed Tit with an adult; we missed the rest of the troupe. A few more captured than last year and included some newly arrived Reed and Sedge Warblers. Four Reed Bunting is unusual, this species has usually sussed out the nets by now. The cut reed area is probably affecting the numbers caught; phragmites is still only about 300mm high.

Weather: Bright, sunny, clear, cool, calm

Present: JL, DL, GB, IW

Nets: 254metres: One 198m standard net ride, additional rides 36m ride in scrub and 18m ride in reed, up from 06:45 to 10:45hrs
