10/05 Thatcham Marsh LNR CES Visit 2025.02

Location: Thatcham Marsh LNR CES Visit 2025.02
Session: 10/05/2025 06:00 to 11:15hrs.
Present: JHW,JL,CMD,IW,JA.
Weather: bright sunny, cool early warm later, light breeze.
Nets: 198M long reed bed ride up from 06:30 to 10:30hrs.
Lures (): None.
Today’s Jay
Notes: A reasonable session, the highlight being the Jay, a first ringing for CMD. We trapped a Chaffinch, but it had the start of grotty foot (papilloma varus) making the leg thicker than normal and it could not be ringed. Most birds were in breeding condition though some Reed and Sedge Warblers had not yet developed BPs or CPs. The Blue Tit ringed at St Marks in 2021 is becoming a regular. JHW brought his coffee machine but unfortunately it developed a gas leak, and fire enveloped the burner unit which he manage to put out fortunately.

Sightings: The Red-legged Partridge (unusual for here) was being harass by two Magpies as
I drove down the track. The Water Rail called from the regenerating reed not the usual place further
up the ride. Four Buzzards soared quite high up, the Swallow was also spotted high up when
watching buzzards. The Oystercatcher flew north at nets down. A good selection of dragonfly and
butterfly on the wing.
