St Aidan's RSPB Reserve has been transformed from an old, open cast mine to a reserve with a rich variety of habitats including reedbeds, wetlands, meadows and woodland. It has a breeding population of Black-necked Grebe, which I was keen to see as I hadn't seen summer plumage birds before. There were lots of Bittern booming and several took to the air during our visit. Otherwise the numbers of singing Warblers - Sedge, Reed and Willow were very impressive along with Reed Buntings and all the usual water birds
