Ptyonoprogne rupestris

Crag Martin - Related to the swallow, Crag Martins breed high up in mountainous terrain. Quite an aggressive bird that will defend its nesting territory from any invaders. They didn't even take kindly to my soft approach in the Algarve at Castro Marim in Portugal where I came across these birds just outside the railway station at Santo Antonio. They prefer nesting in high craggy cliff tops and mountains. It has been know for them to rarely nest in high buildings. Wonderful to watch in flight. Fast strong and agile.
