May Sedge Warbler controls

In the last blog we mentioned that we had caught 4 UK Sedge Warbler controls.
The details were entered into DemOn immediately after the ringing sessions, the new online data entry programme and already we have the ringing details of all of them.

All were ringed as juveniles on autumn migration and now passing through the Teifi Marsh on spring migration.

D994644 was ringed at Squires Down, Dorset  12th August 2016

D879410 was ringed at Orfordness, Suffolk 15th August 2017

S692175 was ringed at Titchfield Haven National Nature Reserve in Hampshire  5th August 2017
It looks like this was a big migration day for them - from Twitter @Trevor_Codlin  "Just shy of 340 birds ringed this AM  mainly sedge (1 Belgium control) & Reed (2 controls UK & France)70 willows 11 groppers"

S816284 was ringed at Keyhaven Marshes, Hampshire 28th August 2017

Since the big days of Sedge Warbler migration last week, the numbers have slowed down with just 20 Sedge Warblers ringed on the last 3 mornings.
Returning Reed Warblers are still slow to return. One from 2016, also seen last spring, was retrapped this morning.
