Lots of migration this morning. Thousands and thousands of swallows heading out over the channel in a steady stream, hundreds by each minute. Also smaller numbers of house martins. Large numbers of meadow pipit overhead or alighting in fields before heading off, also a few skylark, pied wags, flocks of linnet and Siskin. Plenty of chiffchaff in the hedgerows and roadside bushes. Also kestrel, sparrowhawk and buzzard.
