Wednesday 25th August

Counts from the estuary showed a continuing turnover of waders with three Knot in the Bight new arrivals amongst 154 Ringed Plover and 70 Dunlin. Also over the morning high tide 326 Curlew, 110 Sandwich and three Common Tern, eight Whimbrel, four Mediterranean Gull with 500 Black-headed Gull, four Teal and three Bar-tailed Godwit.

Elsewhere 40 Swallow and eight Sand Martin flew through with five Wheatear and a Whitethroat the pick of the grounded migrants.

Wildlife News: The warm, sunny conditions brought out several solitary bee species and good numbers of hoverfly species out in good numbers. Most were on the flowering water mint but an area of Japanese Knotweed held several foraging species, an unexpected benefit.

Amongst the hoverflies Yellow-girdled Dasysyrphus Dasysyrphus tricinctus was a new species for the Recording Area, seemingly a rare species in the southwest. Other species included a few migrant Large Tiger Hoverfly Helophilus trivittatus amongst good numbers of Marmalade Hoverfly Episyrphus balteatus, Hornet Hoverfly Volucella zonaria, Pied Hoverfly Volucella pellucens and Furry Dronefly Eristalis intricaria.
