A session was planned for Tuesday morning, to take place before the forecast rain at about 10. As it was, there was a short sharp shower at about 8, and other than that it was dry, if a bit windy. Six nets were set in the vicinity of the Discovery Hut, and 25 birds were captured, of 13 species. It was great that a lot of the birds were warblers, including 7 Sedge Warblers, 6 youngsters and an adult.
The 2 Chiffchaffs caught were both hatched this year, one was still in its juvenile plumage, and one had almost completed its post-juvenile moult. A Willow Warbler which had also completed its post-juvenile moult, provided a nice comparison to the 2 Chiffchaffs.

A Woodpigeon, only the 18th caught by the Group since 2007, was a nice surprise. The pale green eye and the presence of 2 secondaries which were browner & slightly shorter than the rest of the wing indicate that it was probably a 2nd year bird (age code 5).
