Palpita vitrealis, (above) caught last night in a moth trap on site, is a scarce migrant usually appearing in late autumn, although as is the case with this individual it can be found as early as June or July.

The winds today have gone easterly, so hopes will be high for something special to turn up, unfortunately it hasn't happened for us today. The first wandering young Green Woodpecker of the year did put in a brief appearance, but that and a Yellow Wagtail flying south overhead was about it for today.

4 birds only ringed, 1 each of Dunnock, Chaffinch, Linnet and Blackcap.

The continuing wind from the West, a slight breeze and heavy cloud made for some good conditions for some early, quite interesting visual migration today at the observatory. 

The last 14 days up until today, we have had a considerable amount of Siskin passage through the observatory, with totals now exceeding 400 Siskin in 2 weeks. A total of 201 Siskin passed though over the observatory today heading south, some in nice groups. 

Migrants today included 73 Swift, 9 Sand Martin, 1 Swallow, 1 Common Scoter, 1 Mediterranean Gull, 4 Common Tern, 3 Curlew and 201 Siskin.

After a very warm night, the moth traps were somewhat full of moths, with over 100 species caught  including the 2 species above, which were both new for the site. Purple Clay (top) and Homeosoma nebulella.

Bird wise it is still relatively quiet, but it is beginning to pick up as migrants are starting to appear again. Wader movements are increasing with 26 Curlew and 5 Whimbrel south today, along with 8 Teal and a lone Grey Heron, also heading south, whilst on site "Sylvia Warblers" are starting to turn up as the youngsters start to disperse, with 4 Whitethroats, 1 Lesser Whitethroat and a Blackcap all put in appearances.

14 birds were ringed, 3 Whitethroat, 1 Lesser Whitethroat,1 Blackcap, 1 Song Thrush and 2 each of Greenfinch, Linnet, Dunnock and House Sparrow.
