Early migration and key species

Over the last 4 weeks 487 Sedge and 188 Reed Warblers have been ringed. A minimum, but showing the scale and importance of the Teifi Marshes Reserve. Not only for breeding but also for feeding as they journey south to Africa.

Early season movements to and from the Teifi Marshes

Birds captured from the Teifi Marshes and other TRG sites are shown in the table below..

Linnets are from the Lleine RAS study site, Willow Tit and Whinchat are from Cors Caron- not all species are listed, but are included in the totals..


The post above is a snapshot of the late July - early August ringing this year. A very good spell for warblers in particular the acros. One of the best early autumn's totals and we look forward to the following weeks - a very good breeding season... or an early migration....
