Thursday 20th April

An afternoon and low tide visit, the clear blue sky and may be the time of day, meant migrants were in short supply with just a few Swallow through, a Yellow Wagtail over north, and two Willow Warbler on site.

Elsewhere the Dark-bellied Brent Goose and three Whimbrel were in the estuary and 26 Sandwich Tern and a Great Crested Grebe were offshore.

Wildlife News: Solitary bees were active in the sunshine with the first Black Mining Bee Andrena pilipes of the year, along with Yellow-legged A. flavipes, Chocolate A. scotia and male Sandpit Mining Bee A. barbilabris patrolling the bare sand areas for females. Gooden's Nomada goodeniana and the first Flavous Nomad Bee N. flava were on Alexanders at Langstone Rock and the station respectively.

The fine weather also encouraged hoverflies with many emerging Humming Syrphus S. ribesii on the wing, with lesser numbers of Marmalade Hoverfly Episyrphus balteatus, Grey-spotted Boxer Platycheirus albimanus, Common Dronefly Eristalis tenax and Tiger Hoverfly Helophilus pendulus. Butterflies were represented by at least six Orange-tip, four Peacock and two Speckled Wood.
