Great weather at last for the butterflies

Heysham Obs
The flower-rich grassland next to the office was a hive of activity today with Meadow Brown, Gatekeeper and Common Blue in good numbers.  Ten years ago for Gatekeeper you would have read Wall Brown, but the latter seems to have mysteriously disappeared from this area.  Warblers seem to be moving around a bit with the retrap evidence suggesting at least some of this involves dispersal of locally born birds.  Unusually, two Whitethroat and a Reed Warbler ringed as recently fledged juveniles about 1.5km away at Middleton NR in July have been caught next to the office in the last two days.  In the absence of rings, these would have been labelled as 'early migrants'

Office area
Unringed Sedge warbler, Reed Warbler, Willow Warbler (3) and Chiffchaff but not many Greenfinch today

Red Nab/Ocean Edge well before high tide
Med Gull - at least 4 juvs, 2 x 2CY and at least one adult

A nice mixed catch including a rather late Barred Red (uncommon here), Barred Rivulet, White-line Dart, 3 Dingy Footman, Dingy Shears, Agriphila latistria.  Of the specialities, Bordered Beauty conspicuous by its absence - maybe its having a late emergence like a few other species
