Another very spring-like day today with plenty of insects on the wing including bumble-bees and a Brimstone butterfly or two. I always think that a vivid yellow male Brimstone looks particularly stunning this time of the year, probably because normally the back-drop is dull and uninspiring before the buds and leaves emerge in profusion.
Birds on the move today included winter thrushes, Linnets, wagtails and Meadow Pipits. A Grey Wagtail at Hanging Houghton was part of this northward movement.
A quick wander around at Harrington Airfield failed in an effort to find an early Wheatear, and I had to make do with a Raven, several common raptors and at least one Brambling.
