Near gale/gale force south westerlies made observations an indoor job today. Perhaps because of this we saw our first common and sandwich terns of the year, and in the shelter of the Heligoland we actually had some passerine migrants, two willow warblers. The black redstart was feeding in the lea of the fort as the sun rose.
Brown-tail larval nests are in profusion as the caterpillars start to emerge.
