Saturday 8th August 2015


Bird wise quiet on the migration front with just a couple of new Willow Warblers on site plus a Yellow Wag heading south although several other migrants from recent days are lingering. Very few waders also noted on the move apart from 20 Oyks & 7 Whimbrel heading south plus a Redshank northbound. Frustratingly a shearwater was seen briefly offshore by four observers but it must have pitched in as it seemed to disappear off the planet !

Common Blue butterflies have had a fresh emergence in recent days and are now scattered across the whole site. Moth traps reasonabley busy including this Iron Prominent - a species we only note a couple of times each year.


10 birds ringed: 5 linnet, 2 greenfinch, 1 wood pigeon, 1 robin, 1 willow warbler.

This picture is of the bedeguar gall, more commonly known as robin's pincushion, and found on wild roses. It is caused by the Gall Wasp Diplolepis rosae laying her eggs in the plant stems and when they hatch the tissue swells up to form the gall.

A quiet day with very little in the way of migrants. 1 Wheatear still on the common, and 1 each of Reed Warbler, Chiffchaff and Willow Warbler in the compound,whilst a Whimbrel made a brief stop to rest up before heading off south.

22 birds were ringed, these being 8 Greenfinch, 6 House Sparrow, 5 Linnet and singles of Wood Pigeon, Reed Warbler and Wren.

Serin was unexpected as we have never recorded this species before in early August. Other migrants worth a note include 2 Great-spotted Woodpecker, 2 Reed Warbler, 2 Willow Warbler plus 21 Swallow heading south. A Four-spotted Chaser is always a notable sighting here on a warm sticky morning. The moth traps haven't really picked up following the cold snap last week although they did include the first Grey Dagger noted this year with a Flounced Rustic signifying the autumn is progressing along.

Ringed Plovers 2015



During 2015 five pairs of Ringed Plover reared a total of four young.

One pair reared 3 young on the first attempt with a second attempt failing at the egg stage. A second pair reared 1 young on the first attempt but with no second attempt as one of the adults disappeared during the rearing stage of the first brood. The surviving chick was still being tended for by the remaining adult seven weeks after hatching. A third pair failed at the egg stage on the first attempt & at the chick stage on the second attempt. A fourth pair had two failures at the egg stage. A fifth pair had one attempt failing at the egg stage and then disappeared from the site. It is not thought that any of the pairs laid more than two clutches. Other adults occasionally turned up on site but did not breed.
