Over the past couple of weeks local birders have been finding migrating Wheatears stopping over on the huge pile of rocks that is the Cardiff Barrage, the man-made structure that was built in the 1990s to cut Cardiff Bay off from the Bristol Channel and turn it in to a virtual lake. The Wheatears are returning from over-wintering in tropical Africa and, after taking a short breather on the Barrage, they head further north to their breeding grounds in- and up-land. Unfortunately, I couldn’t locate any Wheatears today but the many Pied wagtails were entertaining, flitting busily hither and yon.
