Location: Thatcham Marsh LNR

Session: 01-Sep-2019 07:00 to 11:30 hrs

Notes: We used Audio for this session having completed visit 12 the final visit of the CES season last weekend. Blackcaps were on the move today and made up 58% of the capture. On last year’s equivalent we had a big capture of 92, we had a bigger variety of species however most species captured this year had similar totals. The exception surprisingly being Blue Tit which seems to be have a much better post fledging survival than last year.

Weather: sunny periods, warm, calm, breezy later.
