A pleasant if squelchy walk at Harrington Airfield this morning provided a further opportunity to witness visible diurnal migration. Fieldfares were the most obvious with undulating flocks steadily progressing south over the top fields, often at low level. Starlings and Redwings were probably the next most numerous with smaller numbers again of Woodpigeons and gulls moving in the same direction. At Harrington it is difficult to ascertain Skylark passage as most of them seem to be simply flying around and chasing each other and often with many singing. Persistent viewing seems to indicate that they do gradually disappear off the south or west, but I think that some birds do recirculate and appear over the fields again once they have completed a circuit or two.
The Linnet flock attracted Goldfinches, Greenfinches, Chaffinches and a Brambling. At least two Short-eared Owls flushed up from the long grass and there were Common Buzzards and Sparrowhawks on the prowl. Sparse migrants included Meadow Pipit, Tree Sparrow and redpoll sp. The broadcast seed at the concrete entrance track is attracting common birds with Chaffinch and Yellowhammer being the most numerous.
