Goodbye, swifts

Well, the swifts are off to Africa for another few months. They seem to arrive in this area around 10th May each year and migrate back in early August. It seems to vary up to two weeks according to weather.
Whilst they are here the swifts are tremendously useful to devour insects over the gardens. They work in groups and their call confuses the insects. Also as a weather forecast, when it is going to rain they fly lower!

It's amazing to think how far these little birds migrate and that they sleep on the wing. this is avideo of the swifts flying very high the night before they left(in case you wondered!)
