18/09 Thatcham Marsh LNR

Location: Thatcham Marsh LNR
Session:  18-Jun-2017 06:15 to 10:30hrs.
Headlines: We decided to do an additional CES visit, finish early and do some maintenance; cut the grass in the rides etc. Things didn’t go to plan however. First just three turned up; Gina and Simon arrived late morning. We decided to cut the rides before putting up the nets and it got to hot. The mower started and then stopped and would not start again also I forgot to bring my PPE so the strimmer was also a non-starter. We put nets up at about  07:30. The capture was ok but the number of Acrocephalus in residence seemed down with Sedge Warbler very scarce. We did capture the first juvenile Reed Warbler of 2017 a very recent fledging its tail being short and still growing. One of the Reed Warbler was a bird ringed elsewhere that we also captured last week; details of original ringing probably know soon after the end of June.
Weather: Weather very hot and humid on the reed bed and calm.
Present: JL, IW, DL and later GB, SC.
Nets: 234metres, 198m standard net ride on the reed bed and 36M in two rides scrub nets up from 07:30 to 10:00hrs
