Summary of contents

Conservation Priority Species: northwest European Bewick’s Swans, a population in decline Whereas most European swan and goose population trends are currently stable or increasing, the northwest European Bewick’s Swan population is of conservation concern because its numbers are in decline. Eileen Rees and Jan Beekman show that although numbers rose during the 1960s-1990s, a co-ordinated international census in January 2005 revealed a 27% decrease on the peak count of 29,277 in January 1995. National trends suggest that numbers have continued to decline since then. A workshop in September 2009 attempted to identify major threats to Bewick’s Swans.

Brown Flycatcher on Fair Isle: new to Britain Paul Harvey recounts the story of how a Brown Flycatcher was found and trapped on Fair Isle on 1st July 1992. BOURC originally placed the record into Category D. Following further British records of the species in 2007 and 2008, BOURC reviewed the first Fair Isle bird, which was accepted as the first British record, and placed all three individuals into Category A of the British List.

Brown, Siberian and Grey-streaked Flycatchers: identification and ageing In the light of recent records of Brown Flycatcher in Britain, Paul Leader looks at the identification and ageing of this species and two closely related potential vagrants from east Asia: Siberian (or Dark-sided) Flycatcher and Grey-streaked Flycatcher.

Letters and notes… include a debate on the authenticity of a historical record of Hawk Owl in Wiltshire, and more observations of the predilection of Goosanders for scrapping with Mallards, Mute Swans and Canada Geese at the local park for bread.
