Yes, it's that time of year again... when swallows and martins (these are house martins) gather into flocks to prepare for the return journey back to Africa. Photographer Chris Knights captured the moment of take-off.
Where do they go? We've known for a long time that swallows go right down into southern Africa, but we're still not sure where our house martins go! They have feathery legs and feet, which makes us suspect that they might circle around high in the sky at night - like swifts do.
Lovely picture, there were a load of swallows around our house today feeding on a hatch of flying ants, maybe they will stay awhile to catch this late summer weather.
Lot to learn
