Sand Martin (Riparia riparia)
The two rivers, the Frome and Piddle run past Wareham and into Poole Harbour and on summer evenings we can see dozens of Sand Martins 'fishing' for insects above the flowing rivers, usually accompanied by House Martins.
Photographing these birds is a real challenge as they fly so swiftly; twisting, turning, swooping. You just get a brief chance when they decide to land on something like this one did. I am sure (s)he didn't need a rest but obviously had some motive for sitting on the fence.
Sadly, all too soon, they will be gone for another year but we still have a couple of months left to enjoy them
