Space-based tracking technology using low-cost miniature tags is now delivering data on fine-scale animal movement at near-global scale. Linked with remotely sensed environmental data, this offers a biological lens habitat integrity and connectivity for conservation human health; global network of sentinels change.
Ecological “big data” Human activities are rapidly altering the natural world. Nowhere is this more evident, perhaps, than in Arctic, yet region remains one of most remote and difficult to study. Researchers have increasingly relied on animal tracking data these regions understand individual species' responses, but if we want larger-scale change, need integrate our understanding across species. Davidson et al. introduce an open-source archive that currently hosts 15 million location points...
Abstract Common cuckoos Cuculus canorus are obligate nest parasites yet young birds reach their distant, species-specific wintering grounds without being able to rely on guidance from experienced conspecifics – in fact they never meet parents. Naïve marine animals use an inherited navigational map during migration but inexperienced terrestrial animal migrants unequivocal evidence of navigation is lacking. We present satellite tracking data common experimentally displaced 1,800 km eastward...
Nocturnal migration of Reed Warblers Acrocephalus scirpaceus was studied by trapping with ‘high nets’ on the Courish Spit (Eastern Baltic) during spring 1998–2000. In spring, left stopover site between 45 and 240 min after sunset (median 84 min), although 85% birds took off 120 sunset. Birds did not arrive until fifth hour sunset; 67% ended their nocturnal flights in penultimate before sunrise, i.e. at dawn. At moment migratory departure, average Warbler body mass 12.79 ± 0.66 g ( n = 60)....
We studied migratory stopovers of nocturnal passerine migrants migrating between the Urals and Siberia Near East Africa (five species) European Russia Indian subcontinent (two in an oasis arid belt northwestern edge western Central Asia. In autumn, fuel loads Blyth's Reed Warblers Acrocephalus dumetorum before their desert crossing were much greater than Palaearctic‐African migrants, which face a narrower barrier, also conspecifics captured during after crossing. However, another migrant,...
Body mass and fat reserves of Sedge Warblers (Acrocephalus schoenobaenus) on nocturnal departure arrival were studied by two methods (capture in high nets playback songs) the Courish Spit (Eastern Baltic, Russia) spring 1998–2000. The average body departing was 13.7 g, arriving birds 13.1 g. difference between masses not significant. calculated flight range still air varied from 19 to 665 km, with a mean 295 km. fuel loads may be explained necessity for Scandinavian populations cross Baltic;...
Many juvenile Reed Warblers perform nocturnal flights before the onset of autumn migration. In our study we tested hypothesis that decision by to such over natal area during post-fledging period depends on weather conditions and phase lunar cycle. We analysed data movements 26 birds radio-tagged near their site Courish Spit (SE Baltic coast). infer from results in take off a flight is triggered intrinsic stimuli only very slightly environmental conditions. Comparison these with previous...
Birds possess behavioural and physiological adaptations which permit them to minimize time energy expenditure during migration in a broad spectrum of winds, for instance, by varying their airspeed. Nocturnally migrating birds were recorded an optical-electronic matrix system, permitted recording images flight parameters the dark. Among medium size birds, Song Thrushes (Turdus philomelos) identified silhouette, linear size, wing-beat pattern, phenology. The equivalent airspeed at sea level...
We examined two cases of first-year Sedge Warblers Acrocephalus schoenobaenus which were ringed in Finland and recovered Estonia on the following day. Environmental/meteorological conditions during nights migratory flights are discussed, together with possible ground speed birds. The birds lost 1.0 1.2 g, respectively, probably entirely from their fat reserves. On basis estimated birds, energy expenditure for flight is discussed. One estimate, 10.9 times BMR, very close to generally accepted...
