Black Redstart

A male in the workshops, where I work at Pemroke Dock- flitting between the overhead cranes. I noticed him at 1:25pm & opened the roller door to let him out. However the lads came back from dinner at 1:30 & closed the door saying they were cold (wimps) I saw it 5 mins later fly into an adjoining shop, but no more. Despite looking around occaisonaly, it seems to have made good it`s escape. I hope so.
