A Summer of Warblers and Petrels

Reed Warbler update..

Adult re-encounters on the Teifi Marshes have slowly increased towards the expected number of returning birds. 163 juveniles have been ringed so far this season. Migration is underway demonstrated by a juvenile Reed Warbler being re-encountered by Gower Ringing Group

Sedge Warbler passage through the Teifi Marshes is quieter than historically but different weather conditions play a big part. No easterlies in particular make a difference. 141 have been ringed since the beginning of July.
