04/08 Thatcham Marsh LNR

Location: Thatcham Marsh LNR CES 2019.10
Session:.04-Aug-2019 06:00 to 11:45hrs
Notes: Conditions ideal today, overcast and calm. The capture although disappointing is not the worst we’ve had. A 28 capture is below the average of 39 for this visit; range 2016-14, 1995-85. Last year’s matching visit total was also poor, and we had additional nets in the scrub, so today’s is quite good given that the reed bed seems all but devoid of birds. The few adults captured were mostly in primary moult. Cetti’s Warblers were singing at each end of the ride this week, none captured today; just one juvenile so far this season. We had a better capture of Reed Warbler than for visit 10 2018 and no Sedge Warblers last year.

Sightings 38 Species: The Bittern was seen by three of us; I missed out! IW and DL saw it fly west just above the scrub by the cars, JHW saw it fly over as we were returning along the ride from a net round, unfortunately for me I was just about to exit the ride and John was behind me, mid-way along the ride; it flew between us. We don’t normally get Bittern here this time of year.
