Misty conditions this morning made for some good observations. Two sedge warblers were in the compound, one of which was singing. A handsome 2nd year male redstart and a tree pipit were the other highlights of a morning of a good diversity of migrants, with 6 species of warbler on the observatory grounds. The first hobby of the year flew north and a swift flew south, along with 4 siskin. 2 yellow wagtails also flew south, before the wind picked up and the passage dried up.
Oak-Tree Pug has occurred consecutively in the the past 5 years, yet was an infrequent visitor before that, perhaps a climate change induced alteration in movement?
Birds Ringed: Blackcap 3, Lesser Whitethroat 1, Linnet 3, Redstart 1, Sedge Warbler 1, Tree Pipit, Whitethroat 1, Willow Warbler 2.
