Location: Thatcham
Marsh LNR
Session: 06-May-2018 05:30 to
10:30hrs
Headlines: A really nice day,
perhaps to bright. It appeared to very quiet acrocephalus-wise on the reed bed,
it proved even quieter in the scrub. We captured a few Reed Warblers at a
steady rate for most of the morning, Sedge Warbler are relatively scarce so
far this year particularly when compared to last year’s visit one capture, when
it look like we picked up passage birds on their way north. Comparison with
last year’s visit one CES is perhaps a little iffy as the season started a
week later. The capture of 25(excluding one from additional nets) was down on
the average of 31. In 2017 there were 28 captured in the standard nets so not
much difference really. Range for visit one is 7 in 1998 to 63 in 2004.

Sightings 47 Species: Ian’s list, a
small flock of House Martins flying about and some Herring Gulls moving west
probably the best birds. The Water Rails were quiet apart from one that buzzed
the end of one of the nets. Most of the “common” summer migrants are in now except,
hopefully, for more Reed and Sedge Warblers. For this site, scarce migrants we
have yet to detect are: Lesser Whitethroat and Grasshopper Warbler.
