Understanding how environmental conditions, especially wind, influence birds' flight speeds is a prerequisite for understanding many important aspects of bird flight, including optimal migration strategies, navigation, and compensation wind drift. Recent developments in tracking technology the increased availability data on large-scale weather patterns have made it possible to use path annotation link location animals conditions such as speed direction. However, there are various measures...
An earlier onset of spring has been recorded for many parts Eurasia in recent decades. This consequences migratory species, both changing the conditions encountered by individuals on reaching sites and affecting cues regulating timing migration where decisions to migrate are influenced local environmental variables. Here we examine two arctic goose populations, pink‐footed Anser brachyrhynchus (during 1990–2003) barnacle Branta leucopsis 1982–2003), which breed Svalbard. The...
Abstract Aim Animal movement is an important determinant of individual survival, population dynamics and ecosystem structure function. Nonetheless, it still unclear how local movements are related to resource availability the spatial arrangement resources. Using resident bird species migratory outside period, we examined distribution resources affects patterns both large terrestrial birds (e.g., raptors, bustards hornbills) waterbirds cranes, storks, ducks, geese flamingos). Location Global....
Recent studies have suggested that protected areas often fail to conserve target species. However, the efficacy of terrestrial is difficult measure, especially for highly vagile species like migratory birds may move between and unprotected throughout their lives. Here, we use a 30-y dataset detailed demographic data from waterbird, Whooper swan (Cygnus cygnus), assess value nature reserves (NRs). We how rates vary at sites with varying levels protection they are influenced by movements...
Abstract Range shifts and phenological change are two processes by which organisms respond to environmental warming. Understanding the mechanisms that drive these changes is key for optimal conservation management. Here we study both in migratory Bewick's swan ( Cygnus columbianus bewickii ) using different methods, analysing nearly 50 years of resighting data (1970–2017). In this period wintering area swans shifted eastwards (‘short‐stopping’) at a rate ~13 km/year, thereby shortening...
Communities are assembled from species that evolve or colonise a given geographic region, and persist in the face of abiotic conditions interactions with other species. The evolutionary colonisation histories communities characterised by phylogenetic diversity, while functional diversity is indicative biotic conditions. relationship between infers whether traits divergent (differing related species) convergent (similar among distantly species). Biotic known to influence macroecological...
Abstract Recent national and international policy initiatives have aimed to reduce the exposure of humans wildlife lead from ammunition. Despite restrictions, in UK, ammunition remains most widespread source environmental contamination which may be exposed. The risks arising use measures taken mitigate these prompted intense sometimes acrimonious discussion between stakeholder groups, including those advancing interests shooting, conservation, public health animal welfare. However,...
Monthly surveys of Bewick's Swans Cygnus columbianus bewickii , Whooper cygnus and Mute olor in Britain Ireland were made during the 1990–1991 winter to determine factors affecting swans' selection feeding sites. Geographic location habitat both influenced site selection. occurred greatest numbers at sites Scotland, northeastern England Northern Ireland, whereas had a more southerly distribution, reflecting differences migratory routes used by these two species. The resident widespread, with...
Approximately 75% of the East Asian Flyway Tundra Swan Cygnus columbianus bewickii population winters in Yangtze River floodplain, China. Historically species was more widely distributed throughout floodplain but now most is confined to five wetlands Anhui Province and Poyang Lake Jiangxi Province, where majority (up 113,000 birds) occur. Within-winter counts suggest that swans congregate at before dispersing other sites later winter. Counts show large between-year fluctuations, declines...
Abstract Illegal killing of wildlife is a major conservation issue that, to be addressed effectively, requires insight into the drivers human behaviour. Here we adapt an established socio-psychological model, theory planned behaviour, explore reasons for hunting Endangered Bewick's swan Cygnus columbianus bewickii in European Russian Arctic, using responses from hunters questionnaire survey. Wider ecological, legal, recreational and economic motivations were also explored. Of 236 who...
