A blog of Aidan Smith's ringing activities - Normally, these take place at sites near Bishop Monkton and in Wharfedale.

Our first post winter check of four Barn Owl boxes produced a pair at a site where they've not bred before. The female, pictured, was already ringed and a control GC85185 (from memory). Fingers crossed for pulli later in the year.
