6th July

The heat returned with a vengeance today and seemed to have restricted fieldwork to the two ends of the day. The best of the numbers at the Bill were offshore, with 47 Common Scoter, 24 Manx Shearwaters, 21 Mediterranean Gulls, 6 Sandwich Terns and singles of Yellow-legged Gull, Little Gull, Black-headed Gull and Common Gull through or lingering. Another pulse of overhead passage included 31 Swifts, 7 Sand Martins and singles of Greenshank and Redshank over the Bill.

A surge in Diamond-back Moth numbers saw 247 trapped overnight at the Obs - the year's highest total to date. More on the moths to follow tomorrow.
