I have been puzzling over these various species for some time now. I take the photographs at a great height as the radio tower on which they perch is tall, a variety of species (martins, swallows and swifts) visit The tower off and on. The photographs I'm posting today are those that might be the Barn swallow. The Red-rumped swallow, the Dusky Craig-martin, and Little swift are residents. Eurasian Crag-Martin and the Barn swallow are winter visitors.
