Résumé :	The breeding population of Northern Wheatears Oenanthe oenanthe at Clee Hill, Shropshire, has been monitored since 1998 as part of the BTO Retrapping Adults for Survival project. Aspects of breeding biology, including laying dates, clutch size and brood size are presented, together with estimates of the return rate of adult birds. There is some evidence that the local population may be declining, with 2009 being a particularly poor year; this may reflect a combination of the national population trend and perhaps deterioration in the habitat for Wheatears in the study area.
