Swifts

20 June 2016
Several cloudbursts produced a stream of swifts fling low over the fields heading south. At first I thought 'Oh no, not autumn migration already', but then remembered that swifts regularly travel over 500 miles a day in search of the insects they catch on the wing and fly ahead of developing weather systems. Swifts breeding in Britain quite often make day-trips to the Continent this way.
