Wheatears - potential for a RAS project?

Sunday morning was spent on the southern slopes of the Preselis with spring traps for Wheatears. A lot of time waiting and watching.....

but success, amongst those caught - this retrap juvenile Wheatear that was ringed as a pullus by Paddy on 27th May. He ringed pulli in 2 nests at this site.
The resident adults did seem much more wary of the traps than Wheatears we have trapped at Mwnt (a coastal site) on migration. There was plenty of food around so our mealworms weren't so tempting.
The site has a good number of breeding Wheatear in a defined area so it does seem to have potential for a future RAS (Retrapping adults for survival) project.
