One Sedge Warbler had been ringed in Portugal in 2015 on its first migration south, the Group's first recovery with a Lisbon ring.

You might have noticed that the maps in this blog look different to our usual Google Earth images. Many thanks to Stephen Vickers for creating the new, easy to use mapping tool.


The garden CES in Llechryd is continuing this year. As ringing has been carried out there since 2008 a lot of old birds are turning up. This Dunnock was ringed in 2013 and not seen since. Although not a UK longevity record it looks like it might be the most number of years since ringing of a Dunnock in Wales.


Not many juveniles have been ringed yet, just a Robin and Dunnocks. Blue Tits are already being seen in post-breeding moult.

If you missed Andy's interesting post about progress with his House Sparrow RAS it is worth a read

House Sparrow April summary


The main activity of several group members in May and June is nest box monitoring. Details of results to follow in a blog post once the breeding season has finished. 

One of Andrew's nest boxes in Ffos Las

Initial comments have been that several boxes failed with high mortality prior to fledging in the stormy weather.
