Session: 21/09/2025 07:00 to 11:15hrs.

Present: JHW,IW,JL,KMB.

Weather: sunny periods, light breeze early, cold strong breeze later, cool early cold later.

Nets: 36+36 metre nets along the reed bed ride up from 07:30 to 10:30hrs.

Lures (audio): (BC-CC-FC-GC-GW-WH-LW-WO),(YW-WC-W.-TP-RT-RZ),(YB),(RT) intermittently.

Notes: Blackcaps on the move for this session (just under 60% of those ringed today) and a couple of straggler Reed Warblers and a Sedge Warbler. The lures called in the Blackcaps, Chiffchaffs and Goldcrest. The numbers of the last should be increasing as we head into Autumn but just still the odd bird so far. All the other species are either attracted by the calls of other species or most likely just passing through. We again have no matching visit from 2024, we only did one session Sep 2024 at the end of the month, the other weekends being unsuitable weather-wise.

Sightings: The first decent flock of Woodpigeon so far this half of the year, seen as we put the nets

up and just after a flock of about 20 Egyptian Geese followed by five more flew north. The Great

White Egret flew towards Lower Farm GP, quite an impressive bird in flight appeared to be a little

larger that Grey Heron. A couple of high flying Magpie flying north is unusual. No hirundine seen and

at least one, maybe more, Siskin over calling at nets down.
