This weekend I made a visit to "Ulva kvarn" in Uppsala. Ulva is an old watermill and the river flows down a waterfall and create an perfect habitat with turbulent water for the White-throated Dipper. The dippers arrive in the authum and stays all winter in to spring when the suddenly disappear. This time there was 3 dippers at the site and I photographed them for a cupple of hours and got som nice pictures.
