Wednesday 4th September

A Spoonbill feeding outside Cockwood Harbour mid afternoon was the highlight with an Osprey, a Curlew Sandpiper and three Little Tern also in the estuary. Counts from the high tides included 292 Redshank110 Ringed Plover65 Sandwich and 10 Common Tern, 54+ Dunlin21 Sanderling15 Black and six Bar-tailed Godwit14 Greenshank14 Knot13 Teal, nine Mediterranean Gulleight Whimbrel, four Common Sandpiper and two Wigeon.

Elsewhere 10 Common Scoter were offshore, with nine Wheatear, four Chiffchaff and two Blackcap on site. 

Other Wildlife: The sunny conditions were favorable for insect migration with good numbers of Small White on the move interspersed with a few Large White and a Red Admiral.  However, the pick was a male Locust Blowfly Stomorhina lunata, a true migrant with increasing frequency in late summer/autumn over recent years. Migrant hoverflies included several Large Tiger Hoverfly Helophilus trivittatus and Marmalade Hoverfly Episyrphus balteatus.

Hoverflies are still frequenting the remaining Water Mint and Common Fleabane, although a Hornet Plumehorn Volucella zonaria found some early flowering Ivy while its relative a Wasp Plumehorn V. inanis was nectaring on Michaelmas Daisy, both will become the main attraction in coming weeks.
