Animal movement is fundamental for ecosystem functioning and species survival, yet the effects of anthropogenic footprint on animal movements have not been estimated across species. Using a unique GPS-tracking database 803 individuals 57 species, we found that mammals in areas with comparatively high human were average one-half to one-third extent their low footprint. We attribute this reduction behavioral changes individual animals exclusion long-range from higher impact. Global loss...
Background Performance of migrating birds can be affected by a number intrinsic and extrinsic factors like morphology, meteorological conditions migration strategies. We compared travel speeds four raptor species during their crossing the Sahara desert. Focusing analyses on this region allows us to compare different under equivalent in order disentangle which affect migratory performance. Methodology/Principal Finding tracked raptors using GPS satellite transmitters from Sweden, Spain Italy,...
Internal factors such as experience (e.g. age) and motivation for breeding, external ones environmental conditions meteorology landscape characteristics) can promote differences in migratory behaviour routes among seasons, regions populations. Using satellite telemetry we investigated whether occur which them migrating Eleonora’s falcons breeding the Mediterranean area (Spain Croatia) wintering Madagascar. We found that during autumn migration no age when crossing Sahara desert, but...
Recent improvements in satellite tracking, such as the miniaturization of transmitters, have enabled study movements an increasing number bird species. The Lesser Kestrel Falco naumanni has been subject numerous studies but detailed information on its migration routes and wintering areas is still lacking. Here, we provide a description routes, timing Kestrels. Five adults fitted with transmitters southeastern Spain were tracked during autumn spring journeys their grounds. overall duration...
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....
Abstract Aim Migratory animals regularly move between often distant breeding and non‐breeding ranges. Knowledge about how these ranges are linked by movements of individuals from different populations is crucial for unravelling temporal variability in population spatial structuring identifying environmental drivers dynamics acting at spatio‐temporal scales. We performed a large‐scale individual‐based migration tracking study an Afro‐Palaearctic migratory raptor, to determine the patterns...
We tagged two juvenile short-toed eagles in southern Italian peninsula with GPS satellite transmitters. According to previous visual observations, different migratory routes for reach Africa autumn have been proposed: via Sicily and Gibraltar. These include over-water distances cross the Mediterranean Sea, thus proportions of flight modes (soaringgliding vs flappinggliding) resulting transport costs. Considering scenarios energy cost transport, flapping-gliding over water being more costly...
Enhancement of information transfer has been proposed as a key driver the evolution coloniality. Transfer on location food resources implies that individuals from same colony share foraging areas and each can be associated to specific area. In colonial breeding vertebrates, colony-specific are often spatially segregated, mitigating intercolony intraspecific competition. By means simultaneous GPS tracking lesser kestrels (Falco naumanni) neighbouring colonies, we showed clear segregation...
Conservation of migratory species faces the challenge understanding ecological requirements individuals living in two geographically separated regions. In some cases, entire population widely distributed congregates at relatively small wintering areas and hence, these become a priority for species' conservation. Satellite telemetry allows fine tracking animal movements distribution those less known, often remote areas. Through integrating satellite GPS data from five populations comprising...
Wind is among the most important environmental factors shaping birds' migration patterns. Birds must deal with displacement caused by crosswinds and their behavior can vary according to different such as flight mode, migratory season, experience, distance goal areas. Here we analyze relationship between wind movements of three raptor species which migrate soaring–gliding flight: Egyptian vulture Neophron percnopterus, booted eagle Aquila pennata, short-toed snake Circaetus gallicus. We...
Departure and stopover decisions are crucial for a successful migration. Such modulated by complex interplay between endogenous (physiological state) external factors, such as weather (e.g. wind) geography (ecological barriers). In this study of the black redstart Phoenicurus ochruros, short-distance migrant passerine, we investigate effect weather, gauged tailwind crosswind conditions, rainfall, temperature, barometric pressure, on departures from site in central Mediterranean Sea, off...
Capsule Eleonora's Falcons wintering in Madagascar selected degraded humid forests and cultivated areas close to pristine forest. Aims To identify the habitat preferences of Falcon Falco eleonorae on their grounds Madagascar, use this information gain insights into conservation priorities species. Methods A total 11 were captured Spain 2007 2008 equipped with solar-powered satellite transmitters. We obtained five complete events for three birds, two them tracked consecutive years. Data...
Capsule Immature Short-toed Snake Eagles hatched in Spain leave their Sahelian wintering grounds to spend the summer northern Africa.
Capsule Five Booted Eagles breeding in Spain were tracked by GPS during migration. Autumn routes generally more eastern than spring routes, showing a typical loop Birds covered on average ca. 200 km/day, and only one individual used long-term stopover site (for up to 4 weeks). All but single wintering area, located Sub-Saharan Africa, at 2800–3500 km from their nests. forced stop migration the Strait of Gibraltar for 6 days.
Background The adaptive transition between behavioral strategies, such as the shift from migratoriness to sedentariness, remains an outstanding question in evolutionary ecology. Density-dependent variation age of first breeding has been proposed a feasible mechanism through which long-lived migratory birds with deferred sexual maturity should become sedentary persist on islands. Although this pattern seems hold for most raptors and herons, few exceptions have identified. One these is...
Capsule The Eurasian Marsh Harrier shows a leapfrog migration pattern with individuals breeding in Northern and Eastern Europe wintering further from their grounds than belonging to the populations of Western Southern Europe. Aims We analyse distribution Harriers relation identify differential area selection strategies. Methods used ring recovery data 320 European population. Latitude longitude ringing sites as well age-class were explain variation distances between areas sites. Moreover, we...

The gateway to Africa: What determines sea crossing performance of a migratory soaring bird at the strait Gibraltar? Journal Animal Ecology , 89, 1317–1328. Migrating birds undertake long journeys which pose several challenges. Water bodies are most demanding ecological barriers for birds, due increase in energy consumption and mortality risk. Through high‐resolution GPS, Santos et al....
Summary Recent advances in bird tracking technologies are revealing that migratory birds use temporal staging sites other than breeding and wintering areas, these areas deserve conservation efforts. Eleonora’s Falcon Falco eleonorae is a long-distance raptor breeds colonially on islands considered priority species for conservation. Anecdotal observations indicate during the pre-breeding period, Falcons stay inland far away from colonies, but, to date there no detailed data concerning...
Migrating juvenile birds rely on endogenous information in choosing the direction which to fly, but such input may be overridden by social interactions with experienced individuals. We tagged seven Short‐toed Eagles Circaetus gallicus GPS transmitters southern Italy. This trans‐Saharan migrant flies mainly soaring and is therefore not well adapted performing long water crossings. Five of juveniles used longer apparently safer route towards Strait Gibraltar, two migrated along a southerly...
