Detecting diurnal migration

Hello

A wander around Harrington Airfield this morning provided plenty of evidence of south-bound migration but nothing of particular note was seen. Common finches made up much of the movement which also included a Brambling and a couple of redpoll sp. Redwings, Starlings and Woodpigeons made in-roads in to the south-westerly air-stream and moved over in small flocks. Skylarks are more difficult to assess because they spend so much time chasing each other around and singing, direct diurnal migration is less pronounced. For the last month or so small numbers of Tree and House Sparrows have been flying over the disused airfield or even pitching down on the bushes for a short while. This may just be localised movement but who knows! Other birds seen this morning included a Wheatear and about sixty Golden Plover.

Birds in the Scaldwell Bay at Pitsford Res today were noted as a single Great White Egret (I'm not certain that the other two are currently on-site, but one has been seen regularly south of the causeway too), 18 Red-crested Pochard, 11 Pintail, a pair of Stonechat and a Willow Tit. A few Siskins were around Christies Copse in the Walgrave Bay. Birds visible from the dam this afternoon in wet and dull conditions included a Water Rail, a Green Sandpiper, up to four Grey Wagtails, a Wheatear and an adult Yellow-legged Gull. 

A Grey Wagtail was in Hanging Houghton village today and three Bramblings flew south over the Brampton Valley below the village. This evening the Short-eared Owl again hunted the southern-most field of the Blueberry Farm complex; a Barn Owl and a pair of Stonechat were present too.

Goldfinch. Large numbers of these
birds pass through the county at this
time of the year, many to winter in Iberia.
