In the July issue of British Birds:
All-dark Oceanodroma storm-petrels in the Atlantic
Bob Flood presents a thorough review of all known records of all-dark storm-petrels in the region. He concluded that the occurrence of a Leach’s Storm-petrel with an entirely dark rump has yet to be proven, and that a small and genuinely all-dark storm-petrel is almost certain to be a Swinhoe’s.
The decline of the Willow Tit in Britain In the first in a new series on UK Conservation Priority Species, Alex Lewis and her colleagues take a look at the dramatic fall in numbers of the British Willow Tit. This paper outlines the three main hypotheses for the decline – increased competition, increased predation and changes in habitat availability – and looks at possible management solutions.
Shorter items include a paper on the second British record of Allen’s Gallinule, letters, notes (including an amazing observation of an Osprey catching a Great Crested Grebe in Northamptonshire), obituaries of both David Snow and Bob Scott, book reviews, news & comment and recent reports.
See the British Birds website at http://www.britishbirds.co.uk for full details of current and back issues, and to download a sample copy of BB.
