TL;DR: The geospatial assignment model now provides a protocol for testing the hypothesis that declining populations winter more in heavily fragmented forests of west Africa compared to the Congo basin, and is encouraged for the investigation of migratory connectivity in other sub Saharan Afrotropical migrants.
Abstract: Wood Warblers Phylloscopus sibilatrix have declined considerably throughout most of their north and western breeding range in Europe but the causes of this decline are unknown Declines may be related to factors on the breeding grounds, stopover sites and/or wintering grounds We used multi-isotope (δ2H, δ13C, δ15N) measurements of winter-grown feathers of 314 individuals breeding in the Bialowieza Forest (E Poland) to infer where they wintered in sub Saharan Africa over a 4-year period from 2009–2012 We used both aspatial and spatially specific assignment techniques involving a previously developed clustering algorithm related to long-term patterns of precipitation (δ2H) and theoretical plant-based isoscapes (δ13C, δ15N) for Africa We determined that our breeding population was consistently assigned to the forested region of the Congo basin Males were more depleted in 13C and 2H and more enriched in 15N than females suggesting potential sexual habitat segregation on the wintering grounds We

TL;DR: The northern islands of Scotland hold the bulk of British and Irish Arctic Terns and it had been feared that this population was in decline, and in 1980 a survey was held to establish the facts.

TL;DR: The implication of these results was that, well before reaching maturity, White-tailed Eagles used dispersal movements, at least in part, to assess potential breeding sites, and thus dispersal behaviors were not simply directed toward survival alone.
Abstract: In long-lived raptors with delayed maturity, the period between fledging and settlement on a breeding site may take several years and is poorly understood. In our study of a reintroduced population of White-tailed Eagles (Haliaeetus albicilla), we investigated movements during this transient (juvenile dispersal) phase of natal dispersal using records of wing-tagged birds. Maximum juvenile dispersal distance (JDD), as measured from natal (or release) sites to locations recorded prior to birds settling on a breeding site ranged from 18 to 200 km in different individuals. Observation records suggested that (1) the most extensive movements occurred in the first two years after fledging, (2) males initially dispersed further than females, but, in their second year, females tended to be further from their natal site than males, and (3) as breeding age approached, males were closer to their natal sites than were females. Maximum JDD did not differ between wild-bred and released (reintroduced) birds and ...

TL;DR: Offsite and onsite metrics provide high levels of temporal and spatial resolution with a high degree of flexibility and could add reliable information to traditional social surveys and represent an opportunity to improve the understanding of the drivers of interest in conservation.

TL;DR: The results add support to calls to eradicate mice from Gough Island and more generally, mice cannot be ignored as a potential threat to island fauna, and island restoration and management plans should routinely include eradication of introduced mice.
Abstract: The impacts of predation by invasive mammals on island fauna are a major driver of insular biodiversity loss. Devastating, hitherto unsuspected impacts of predatory house mice on breeding seabirds have been described recently. We studied the fate of 178 Atlantic Petrel Pterodroma incerta nests at Gough Island, over four seasons, from October 2003 to January 2008. Introduced house mice Mus musculus were found in all study burrows checked for mouse visits. From October 2003 to September 2004, we video-recorded attacks by mice on six (of 13) live, healthy Atlantic Petrel chicks and on one (of three) great shearwater Puffinus gravis chicks. In all years, chicks died from mouse attacks. Stage-specific daily nest survival rates were modelled, from which estimates of breeding success were derived that accounted for the variable exposure periods studied among years. Average daily survival rate of eggs was 0.998, and hatching success through the entire incubation period (55.5 days) was 0.924 [95% confidence interval (CI) 0.903–0.940]. Daily chick survival rates were 0.990, which gave a modelled fledging success of 0.247 (CI 0.165–0.338) over the 138-day chick period, and average annual breeding success (chicks fledged per breeding attempt) of 0.228 (CI 0.150–0.318), which is low compared with congeners. Productivity estimates were used as a parameter in a population simulation model, which predicted a population multiplication rate (λ) of 0.993 (CI = 0.966–1.021). However, in the one season studied from laying to fledging (2007), from 58 nests, only one chick fledged (1.7%). This suggests the wide errors on the model results may obscure a more severe reality. More than 60% of model simulations resulted in an International Union for Conservation of Nature classification of Endangered. Our results add support to calls to eradicate mice from Gough Island. More generally, mice cannot be ignored as a potential threat to island fauna, and island restoration and management plans should routinely include eradication of introduced mice.
