Early nesting does not result in greater productivity in the multi-brooded Woodlark Lullula arborea
Jul 01, 2008; Mallord, John W; Dolman, Paul M; Brown, Andy; Sutherland, William J ... Capsule Birds that started nesting early and made more nesting attempts did not produce more fledglings or recruits. Aims To investigate seasonal trends in reproductive performance of a multi-brooded ground-nesting passerine, and whether re-nesting compensates for loss of productivity to ...

Methods A revised Great Britain (GB) wintering population estimate for Red-throated Divers was ...
Sequential use of holes by birds breeding in a natural boreal forest in Mongolia
Jul 01, 2008; Bai, Mei-Ling; Mühlenberg, Michael ... Capsule Wood Nuthatch Sitta europaea and Coal Tit Periparus ater had a high tendency to reuse nest-sites, and holes in living trees were more frequently reused than holes in dead trees. Aims Patterns of sequential nest-hole use are important in understanding the inter- and intraspecific ...
Breeding bird populations of Irish peatlands
Jul 01, 2008; Bracken, Fintan; McMahon, Barry J; Whelan, John ... Capsule Peatlands are very important habitats for birds despite low species diversity. Aims To describe the variation in breeding bird populations that occur on different types of Irish peatlands and their associated habitat characteristics. Methods Bird abundance and diversity ...

Jul 01, 2008; Stevens, Danaë K; Anderson, Guy Q A; Grice, Philip V; Norris, Ken; Butcher, Nigel ... Capsule Avian predators are principally responsible. Aims To document the fate of Spotted Flycatcher nests and to identify the species responsible for nest predation. Methods During 2005-06, purpose-built, remote, digital nest-cameras were deployed at 65 out of 141 Spotted ...
