May 4th. Quite cloudy but sunny intervals throughout and occasional showers in the late afternoon, with increasingly fresh northerly wind.

Early news was of a Hawfinch was by Mill Pond early morning briefly before flying off south down West Dunes. On the sea were 2 Eider, going north were 2 Common Scoter, 188 Little Tern, 2 Artic Tern, 8 Sandwich Tern, a Red-throated Diver, a Great Northern Diver (08.20am) and 10 Gannet.

On the water bodies were 9 Gadwall, 59 Avocet, 2 Whimbrel, 48 Black-tailed Godwit, a Greenshank, 3 Great White Egret and a Marsh Harrier. Elsewhere around the reserve there were 3 Swift (south), a Cuckoo, 100 Oystercatcher, 2000 Grey Plover, 8 Whimbrel, 80 Bar-tailed Godwit, 1200 Dunlin and 2 Jay (south).

Of interest a colour-ringed Avocet on Tennyson's Sands turned out to be a bird originally ringed on the 10th June 2021 on the Castletown Estate in Cumbria UK. The colour ring sightings reports show that the bird has spent much of its autumns around Frampton Marsh, Middle Marsh, Alkborough and North Killingholme Haven Pits. This is the first time it has been recorded during the early part of the breeding season so maybe it will stay around and breed on the reserve.

Bat Research Project: A brilliant effort by Jane Harris, Ian Nixon and the Lincolnshire Bat Group resulted in the trapping of 10 Nathusius Pipistrelle Bats overnight. Six were fitted with Motus tags to enable them to be radio-tracked. Remarkably, a further Nathusius Pipistrelle Bat that had been tagged on the Suffolk coast in late April had arrived at Gib and was detected during the survey.
