The first two images show today's bird and the bottom shows last year's bird of 20 May. Retained juvenile feathers show today's bird to be a first year. The black mantle, forehead and ear coverts show it to be a male, a female looking like last year's bird. The white primary bases extend beyond the primary coverts by 7mm, as would be shown by the nominate form. (c) Richard Brown

The weather today was appalling. Heavy rain at angles approaching the horizontal kept the majority of observers indoors for the majority of the day. Happily Hugo Weigold developed an apparatus on the German island of Helgoland whilst establishing the first bird observatory there. His funnel trap meant that birds could be trapped in weather where other trapping techniques could not be used. Just such weather is a regular feature of Bardsey and the Heligoland Trap in the back garden of the Observatory means we can catch a few birds when the mist nets are not an option. Today we owe Mr Weigold quite a thank you as his trap produced both a Woodchat Shrike and a Melodious Warbler.
