Abstract Migratory species experience various conditions and events throughout their annual cycle that influence spatial demographic dynamics. To understand these dynamics, it is essential to describe the origin destination of individuals. connectivity, which defined as geographic linkage between populations across cycle, increasingly incorporated in population models relate trends environmental variables at different stages cycle. However, such information on migratory movements obtained...
Abstract As a result of agricultural industrialisation, traditionally managed habitats have dramatically declined throughout Europe. result, farmland specialists across several taxa become increasingly threatened. Concurrently, altered farming practices also contributed to the emergence novel habitats, such as Christmas tree plantations, but knowledge their impact on biodiversity is still scarce. In following study, we analysed drivers behind territory selection four declining birds—Common...
Abstract Europe holds globally important populations of breeding waders. However, most the species are in steep decline, including Eurasian Curlew ( Numenius arquata ). Here, we studied breeding-territory and nest-site preferences a subpopulation that has, contrast to overall trend, been increasing, on East Frisian Islands (Wadden Sea National Park Lower Saxony, N Germany). The islands mostly free from ground predators intensive agriculture thus offer opportunity examine habitat largely...
EU member countries and the UK are currently installing numerous offshore windfarms (OWFs) in Baltic North Seas to achieve decarbonization of their energy systems. OWFs may have adverse effects on birds; however, estimates collision risks barrier for migratory species notably lacking, but essential inform marine spatial planning. We therefore compiled an international dataset consisting 259 migration tracks 143 Global Positioning System-tagged Eurasian curlews (Numenius arquata arquata) from...
Urbanisation has contributed to a severe decline in biodiversity worldwide. However, urban ecosystems can also play an important role the conservation of threatened species, including ground-nesting birds such as Eurasian Oystercatcher (Haematopus ostralegus). While coastal populations this shorebird have declined sharply, there is growing evidence that pairs nesting on flat roofs high reproductive success. reasons for rooftop and species' habitat use areas remain poorly understood. In...
Abstract The Short-eared Owl ( Asio flammeus ) inhabits open grasslands and belongs to the ground-breeding birds that have experienced most severe declines during recent decades. Here, we studied nest fledgling survival of owl species in relation (i) habitat composition, (ii) vegetation structure, (iii) weather conditions (iv) vole abundance. study was conducted on East Frisian Island Spiekeroog (southern North Sea, Lower Saxony, Germany), which harbours one last remaining permanent...
Many farmland birds, such as the Eurasian Curlew (Numenius arquata; here in after Curlew), are steep decline. So far, decreased reproduction and, hence, an insufficient number of offspring to compensate for adult mortality has been considered main driver recent population collapse. However, despite extensive conservation measures most breeding areas, there no signs a general reversal trend. Accordingly, focus on decreasing outside areas well. For Curlews NW Germany, ring recoveries suggest...
The Eurasian Curlew is an endangered migratory shorebird benefiting from numerous conservation efforts in Europe, including the remote tracking of individuals to document habitat use and migration strategy. Formerly hunted France, species subject a hunting ban since 2020. By analysing data collected by multi-sensor tags deployed on curlews, we were able four poaching cases this bird. Using geolocations, instant acceleration, temperature, battery charge charging current, determined place time...
Agricultural intensification and abandonment have led to a dramatic decrease of semi-natural grasslands such as low-intensity pastures hay meadows. The Short-eared owl (Asio flammeus) is ground-nesting raptor open that has severely suffered from these changes. We studied the habitat preferences this umbrella species in its last permanent breeding area Germany (East Frisian Islands, southern North Sea). analysed breeding-territory based on 576 territories six islands. Moreover, we assessed...
Capsule Migration associations by Eurasian Curlews Numenius arquata are temporary and last for single flight bouts between stopover sites.Aims Migrant shorebirds known to initiate migration communally, with groups of birds departing simultaneously from wintering or post-breeding fuelling sites, though the duration such migratory is not known.Methods Wintering breeding adult Curlews, some hand-reared juveniles, were equipped GPS tags record their migration.Results We describe four cases joint...
