Location: Thatcham Marsh LNR CES Visit 2025.05

Session: 08/06/2025 06:00 to 11:15hrs.

Present: IW,JL,IQ,LC.

Weather: cloudy early clearing to sunny, cool early warm later, light breeze got stronger later.

Nets: 198M long reed bed ride up from 06:30 to 10:30hrs.

Lures (): None

Notes: Another low total, the Reed and Sedge Warbler numbers on the reed bed seem to have dropped, possibly the recent rains have affected them. Five fledgling Reed Warblers ringed, the CES 2024.05 matching visit had no juveniles. The breeding season in 2025 looks to be a little advanced compared to 2024. Other juveniles ringed today were the Whitethroat and Chiffchaff (photos above). We don’t get many Whitethroat on the marsh so not sure where this youngster came from. Expected to get some tit families but just the odd individual detected.

Recaptures: (10)

around. Otherwise, nothing of note or unexpected.
