Abstract Long‐distance migrations are among the most physically demanding feats animals perform. Understanding potential costs and benefits of such behaviour is a fundamental question in ecology evolution. A hypothetical cost migration should be outweighed by higher productivity and/or annual survival, but few studies on migratory species have been able to directly quantify patterns survival throughout full cycle across majority species’ range. Here, we use telemetry data from 220 Egyptian...
Human-induced direct mortality affects huge numbers of birds each year, threatening hundreds species worldwide. Tracking technologies can be an important tool to investigate temporal and spatial patterns bird as well their drivers. We compiled 1704 records from tracking studies across the African-Eurasian flyway for 45 species, including raptors, storks, cranes, covering period 2003 2021. Our results show a higher frequency human-induced causes than natural taxonomic groups, geographical...
Disentangling individual- and population-level variation in migratory movements is necessary for understanding migration at the species level. However, very few studies have analyzed these patterns across large portions of species' distributions. We compiled a telemetry dataset on globally endangered Egyptian Vulture Neophron percnopterus (94 individuals, 188 completed journeys), tracked ~70% global range, to analyze spatial temporal variability within among individuals populations. found...
Migratory connectivity describes to which degree different breeding populations have distinct (non‐overlapping) non‐breeding sites. Uncovering the level of migratory is crucial for effective conservation actions and understanding evolution local adaptations routes. Here we investigate migration patterns in a passerine bird, great reed warbler Acrocephalus arundinaceus , over its wide Western Palearctic range using geolocators from Spain, Sweden, Czech Republic, Bulgaria Turkey. We found...
Abstract Aim The extent to which individuals from different breeding populations mix throughout the non‐breeding season (i.e. ‘migratory connectivity’) has important consequences for population dynamics and conservation. Given recent declines of long‐distance migrant birds, multipopulation tracking studies are crucial in order assess strength migratory connectivity identify key sites en route . Here, we present first large‐scale analysis migration patterns globally near‐threatened European...
Light‐level geolocators are currently widely used to track the migration of small‐sized birds, but their potentially detrimental effects on survival highly aerial species have been poorly investigated so far. We recorded capture–recapture histories 283 common swifts Apus apus and 107 pallid pallidus breeding in 14 colonies Italy, Spain, Sweden Switzerland that were equipped with 10 different types (‘geolocator birds’), compared of, respectively, 215 101 not (‘control birds’). Data analysed...
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...
The objective of this study was to determine the prevalence and diversity coagulase-negative staphylococci (CoNS) species from wild birds in Spain, as well analyze antimicrobial resistance phenotype/genotype virulence gene content. During 2015-2016, tracheal samples 242 were collected different regions Spain for recovery. identification performed using MALDI-TOF. phenotype genotype investigated by disk diffusion method PCR, respectively. presence genes lukF/S-PV, tst, eta, etb, etd scn PCR....
Symbionts are key elements of ecosystems, by playing important roles in shaping the biology and ecology their hosts. However, factors determining symbiont loads across host species still unclear. Nowadays, we know that intensity prevalence feather mites, most diverse group avian ectosymbionts, differ strongly between species. To understand those differences, studied 17 bird traits two mite community features (species richness composition species) potentially related to interspecific...
ABSTRACT Anthropogenic activities threaten many wildlife populations by increasing mortality rates, making it crucial to identify the locations and causes of inform conservation actions. Technological advancements, such as GPS satellite tracking, enable precise recording movements. High‐resolution data from devices can facilitate rapid carcass recovery provide insights into tagged individuals. Obtaining required information determine these is complex, standardized approaches overcome...
The Eurasian black vulture (Aegypius monachus) has experienced a severe decline during the last two centuries and is globally classified as near-threatened. This led to extinction of many traditional breeding areas in Europe resulted present patchy distribution (Iberian Balkan peninsulas) Western Palearctic. In study, we describe current genetic status European populations using both mitochondrial cytochrome b sequences nuclear microsatellite markers, comparing with those found Asia...
Molt patterns are poorly understood in most large bird species; however, they of paramount importance the development surveys which age is a key parameter. From 2000 to 2011, we studied body condition and molt 214 Griffon Vultures (Gyps fulvus) Spain. Adult ("griffons") demonstrated poor winter during incubation period, then improved after hatching. Conversely, subadults were fairly uniform throughout year, with their slightly inferior that adults year (except period). The period lasted from...
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...
White stork (Ciconia ciconia) may act as a reservoir and vehicle of cephalosporin resistant (CR) Escherichia coli. Between 2011 2014, we sampled white storks from colonies exposed to different degrees anthropic pressure across the major areas natural distribution in Spain. Cloacal swab samples (n = 467) were obtained individuals belonging 12 six regions. Additionally, 70 collected recently deposited droppings at base nesting platforms. We phenotypically characterized E. coli isolates,...
Spectacular long-distance migration has evolved repeatedly in animals enabling exploration of resources separated time and space. In birds, these patterns are largely driven by seasonality, cost migration, asymmetries competition leading most often to leapfrog where northern breeding populations winter furthest the south. Here, we show that highly aerial common swift Apus apus, spending nonbreeding period on wing, instead exhibits a rarely found chain pattern, southern Europe migrate...
Long-distance migrants are suffering drastic declines in the last decades. Causes beneath this problem complex due to wide spatial and temporal scale involved. We aim reveal migratory routes, stopover areas, wintering grounds, strategies for most southwestern populations of near-threatened European Roller Coracias garrulus order identify conservation key areas non-breeding stage species. To end, we used tracking data from seven satellite transmitters fitted birds breeding different...
Understanding why host species differ so much in symbiont loads and how this depends on ecological traits is a major issue the ecology of symbiosis. A first step inquiry to know whether observed differences among are species-specific or more related with host-symbiont environmental conditions. Here we analysed repeatability (R) intensity prevalence feather mites partition within- among-host variance components. We compiled largest dataset far available: 119 Paleartic passerine bird species,...
