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...
Abstract Wind turbines and power lines can cause bird mortality due to collision or electrocution. The biodiversity impacts of energy infrastructure (EI) be minimised through effective landscape‐scale planning mitigation. identification high‐vulnerability areas is urgently needed assess potential cumulative EI while supporting the transition zero carbon energy. We collected GPS location data from 1,454 birds 27 species susceptible within Europe North Africa identified where tracked are most...
24th of August 2013. The day started as any other capture in the Negev desert, Israel, with 36 griffon vultures (Gyps fulvus) waiting inside trap operated by Israeli Nature and Parks Authority (INPA). They were about to be released back nature after receiving a wing tag, and, for few chosen ones, also GPS transmitter (Iezekiel et al., 2003). One these vultures, later named Rehovot, was merely months old when he received his first nickname: Y64 (the number tag). young male weighing 8.3 kg,...
The use of GPS tracking technologies has revolutionized the study animal movement providing unprecedentedly detailed information. characterization accuracy and precision under different conditions is essential to correctly identify spatial temporal resolution at which studies can be conducted. Here, we examined influence fix acquisition interval device deployment on performance a new GPS/GSM solar powered device. Horizontal vertical locations were obtained intervals (1min, 20 min 60 min) in...
Human-induced environmental changes are changing the migration patterns of birds worldwide. Species adjusting timing, shortening and diversifying migratory routes or even transitioning towards residency. While ultimate causes driving in well established, underlying mechanisms by which species adapt to change remain unclear. Here, we studied recent rapid loss behaviour Iberian white storks Ciconia ciconia, a long-lived previously fully through African-Eurasian flyway. We combined 25 years...
The development and miniaturization of GPS tracking devices has enabled a better understanding migration phenology, but it can be challenging to identify where when starts ends, researchers rely on multiple methods infer it. Here, we use tracks 18 trans‐Saharan migrant White Storks Ciconia ciconia determine how the choice method influences estimation migratory timing discuss its implications. We evaluate provide R code for implementation five alternative methods: spatial threshold, absolute...
Studying the mechanisms shaping age-related changes in behavior ("behavioral aging") is important for understanding population dynamics our changing world. Yet, studies that capture within-individual behavioral wild populations of long-lived animals are still scarce. Here, we used a 15-y GPS-tracking dataset social obligate scavenger, griffon vulture (
Uncovering the ways in which pathogens spread has important implications for population health and management. Pathogen transmission is influenced by various factors, including patterns of social interactions shared use space. We aim to understand how behavior griffon vultures (Gyps fulvus), a species conservation interest, influences presence or absence mycoplasma, group bacteria known cause respiratory diseases birds. investigated direct indirect wild, different situations, impacted...
Abstract Mycoplasmas are known as commensals and pathogenic bacteria of various raptor species causing clinical or subclinical infections. However, little is about the prevalence mycoplasma in captive wild raptors its significance to their health. In Israel, Griffon vulture ( Gyps fulvus ; hereafter Griffons) considered critically endangered, intensive management program includes population monitoring restocking (captive-born imported rehabilitated Spanish Griffons). Here we survey...
Studying the spatial–social interface requires tools that distinguish between social and spatial drivers of interactions. Testing hypotheses about factors determining animal interactions often involves comparing observed with reference or ‘null’ models. One approach to accounting for in models is randomizing movement paths decouple phenotypes while maintaining environmental effects on movements. Here, we update a model detects attraction above effect constraints. We explore use our...

Migration phenology is shifting for many long-distance migrants due to global climate change, however the timing and duration of migration may influence environmental conditions individuals encounter, with potential fitness consequences. Species asynchronous migrations, i.e., variability in timing, provide an excellent opportunity investigate how experience during can vary affect migratory performance, route, destination migrants. Here, we use GPS tracking accelerometer data examine if...
ABSTRACT Conservation translocations (reinforcements and reintroductions) are central for managing various endangered species, yet, their implementation is logistically financially challenging. Because many fail due to the mortality of released individuals, identifying preventing these factors crucial. Here we examine risk affecting post-release survival Griffon vulture ( Gyps fulvus ). The Israeli population facing extinction, recovery efforts by local Nature Parks Authority include...

Bird migratory journeys are often long and hostile, requiring high energetic expenditure, thus forcing birds to pause between flights. Stopover sites allow migrants replenish fuel reserves rest, being crucial for the success of migration. Worldwide, increasing accumulation waste on landfills rubbish dumps has been described provide superabundant food resources many bird species not only during breeding wintering seasons but also migration, used as stopover sites. Using GPS-tracking data...
Abstract Alternative migratory strategies can coexist within animal populations and species. Anthropogenic impacts shift the fitness balance between these leading to changes in behaviors. Yet some of mechanisms that drive such remain poorly understood. Here we investigate phenotypic differences, energetic, behavioral, trade‐offs associated with four different movement (long‐distance short‐distance migration, regional local residency) a population white storks ( Ciconia ciconia ) has shifted...
