Location: Thatcham
Marsh LNR CES visit 17.12
Session: 27-Aug-2017 05:30 to
10:30hrs
Headlines: The last CES visit of
the year. A noticeable difference to
2016's visit 12 is fewer Reed Warblers and Chiffchaffs this year. A capture of 32 is a
little below the average of 33 for visit 12; range 2006-11 1995-71. The total
capture for the season is 405, below the average of 475 for the 25 years of this CES ; range 2014-337 1995-769. Diversity is down, 18 species
captured over the season; range 2006-17 1995-27
The totals for our target species are as follows:
Reed Warbler 171, the average is 209
range 2008-127 1995-302
Sedge Warbler 49, the average is 97
range 2016-47 1995-215
Cetti’s Warbler 24, the average is
17 range 1993-0 2014-34 This species has been steadily increasing since it first
bred in 1994 and peaked in 2014 but numbers show a decline since. It has been
an interesting 25th season and not as bad as it might have seemed, wonder what next year will bring. A decent spring and summer with less rain would be good.

hot
Present: JL, IW, JHW, EMH,JPM
Nets: 198metres on one reed bed standard net ride up from

Recaptures: 11, all recent
except: Cetti’s Warbler 1y 139d, and 350d Blue Tit 5y 315d
Nice to capture a Sedge Warbler today, perhaps the last of the year
Sightings 43 Species: Ian's list is quite busy today. Water Rails were very noisy, probably juveniles being kick out. A calling Marsh Tit again also Garden Warbler, a hard to find species now they have stopped singing. A couple of Swifts over; most have long gone south.
