A new Chiffchaff, and a couple more Sedge Warbler recoveries to think about...
A Chiff with Helgoland ring, that we caught in April 2014. We are still waiting to hear when and where this was ringed but news this week of one that we ringed 8th August 2014 that was caught in south west France at Etang-de-Moisan, Messanges, 74 days later on the 21st October.
Where did these Chiffs come from ??
These recoveries show us how our Sedge Warblers progress, we know West Africa is the destination.
The movements of our Reed Warblers is not as obvious.
We have great retrap data on site fidelity and longevity, but we don't hear much about our Reed Warbler stopover on their migration.

This makes the study of our Teifi marsh so fascinating and valuable.
Our CES and RAS projects provide useful data on our breeding birds, but it is our recoveries and controls that tell us how valuable we are as an important feeding stopover site for migrants.
