Wildlife survey at Upton Fen

A group of six of us - Andrew, Joyce, Peter, Sue, Linda and yours truly are taking part in a year-long survey of the plants and animals of Upton Fen: today was the first of five sessions, involving a seven mile walk around the reserve recording Odonata, Lepidoptera, plants and animals.
My input is, naturally, the dragons, butterflies and birds, and everyone brought some special area of expertise to the group. Today we recorded 51 bird species, as well as seven dragons and damsels and seven butterflies. Most interesting were the Wall Browns: literally dozens of these gorgeous creatures were encountered as we walked around.
