We renewed our acquaintance with an old friend today when this Sedge Warbler popped up in a mist-net in the Crown Estate Field; the ring number looked familiar and it turned out to be a bird ringed here as a youngster on outbound passage on 18th September last year. That date's getting pretty late in the season for a Sedge Warbler (last year only 11 of the autumn's all-time record total of c350 were ringed after this bird) but this bird clearly made it to its winter quarters and returned - presumably to Britain - again this year; it's also got tardiness out of its system since, if we had a check of the data, we wouldn't mind betting that this year's departure date of 12th August must be very close to our median date for autumn Sedge Warblers © Martin Cade:
Immigrant-wise, mothing in the recent blistering heat has been a little lame, but there has been a fair bit of local movement afoot. Cabbage Piercer Selania leplastriana is extremely range-restricted in Britain although easy enough to find amongst Wild Cabbage on West Cliffs at Portland - today's single at the Obs was one of very few to ever make it into the moth-traps there:
Eyed Bell Eucosma pupillana and Starry Pearl Cynaeda dentalis are also both very range-restricted specialities of Portland that are straightforward to find in the vicinity of their larval foodplants - Wormwood and Viper's Bugloss respectively - but rarely stray far away from them:
For us, the best capture in recent nights has been this Roseate Marble Celypha rosaceana; although reported to be 'occasionally common' in the Victorian era we have no evidence of it being anything other than a very infrequent stray/immigrant to the island in modern times © Martin Cade:
