Coloniality is one of the most common strategies in birds. While the lesser kestrel (Falco naumanni) is a colonial raptor during the breeding period, it is not known whether individuals from the same breeding colony aggregate during the non-breeding period too. We GPS-tracked 40 adult lesser kestrels from different Spanish breeding colonies to stud...

High-resolution GPS/GSM dataloggers provide spatial information of the highest quality, which outperform previous tracking methods, such as Argos telemetry or conventional VHF ground-tracking. As a result, this has improved our knowledge of home-range behavior and spatial ecology of many species, including large raptors. In this paper, we use high-...

Studies focusing on the spatial ecology of the Red Kite (Milvus milvus) during the breeding season are scarce, despite this season having major importance in its conservation. Spain has one of the largest breeding populations of this species, but it is very threatened in this country. Here, 28 Red Kites were tagged in Spain with GPS satellite trans...

Se marcaron 6 buitres en la Sierra de Guadarrama y se estudió su ecología espacial a lo largo de dos décadas. En este póster presentamos de manera visual cómo varia su área de campeo a lo largo de los meses.

It was assumed that the Spanish breeding population of the red kite (Milvus milvus) was resident, hence their movements were restricted to their breeding area for their entire lifecycle. However, recent observations indicated that the post-reproductive strategies of the red kite in Spain are more diverse. We tagged 47 breeding adult red kites in Sp...

The current advent of GPS/GSM technology, with high resolution GPS dataloggers available, provides information of the highest quality, which is certainly better than previous tracking methods such as ARGOS telemetry or conventional VHF ground-tracking. As a result, this has improved our knowledge of home-range behavior and spatial ecology of many s...

Background. Little is known about the interaction between predators and wildfires, in part because the large home range and scarcity of predators make their study difficult, and their response is strongly species-specific. Aims. In this paper, we study, for the first time, the effect of wildfire on the behaviour of Bonelli’s eagles (Aquila fasciata...

1. The knowledge about territoriality and space use by predators is a topic of great interest in the study of animal behavior and conservation biology. Examining the plasticity of territory limits, the topology and how territories can be modi ed depending on their owners is important to deepen into the behavior of territorial species. 2. Here, we...

The juvenile dispersal of raptors is a crucial stage that stretches from parental independence to the establishment of the first breeding area. Between 2012 and 2020, 44 juvenile red kites (Milvus milvus) from the Spanish breeding population were tagged using GPS telemetry to study their dispersal. Juveniles left the parental breeding area at the e...

La mayoría de los milanos reales del viejo continente son migradores. Tienen sus áreas de reproducción en Centroeuropa y de invernada en el sur del con-tinente, pero tanto en un lugar como en otro existen pequeñas poblaciones sedentarias que no realizan estas migraciones intracontinentales. En el caso de España, existen alrededor de 2.312-2.440 par...

138 red kites (Milvus milvus) were tagged with GPS/satellite transmitters between 2009 and 2020 in different locations within the distribution area of the species in Spain. This work was the result of a high tagging effort over more than a decade. Hundreds of thousands of locations have been recorded, which allowed to understand the spatial and mig...

La migración es un movimiento latitudinal periódico que tiene lugar en gran cantidad de aves, que se desplazan cientos o miles de kilómetros entre dos regiones bien diferenciadas. Existen dos periodos migratorios cada año. Uno es la migración de primavera, o migración prenupcial. Como su nombre indica, es aquélla en la que las aves viajan desde sus...

La invernada en las aves rapaces es un periodo fundamental para su desarrollo y supervivencia. Las condiciones invernales son más exigentes para los organismos, tanto en términos climáticos como por la escasa disponibilidad de alimento. Por este motivo, gran cantidad de especies adoptan la migración como estrategia para sortear las dificultades, co...

La dispersión juvenil o dispersión natal es el conjunto de movimientos explora-torios que realizan las aves antes de llegar a la edad adulta. En esta etapa, los juveniles tienen un comportamiento distinto al de los adultos, por lo que se la considera una etapa diferenciada con características propias. Los movimientos dispersivos juveniles se caract...

Las aves rapaces suelen adoptar dos estrategias tras la época de cría: el sedentaris-mo y la migración. Las aves sedentarias, o residentes, son aquellas que permanecen en torno a un mismo territorio sin realizar desplazamientos importantes durante el año. Las aves migradoras, al contrario, se desplazan cientos o miles de kilómetros tras la reproduc...

ContextMovement ecology contributes valuable information about animal interactions with the environment, and their responses to landscape-level anthropogenic impacts. Big cats are vulnerable to such changes, but the current deficit of information about home range movements, limits the scope of conservation initiatives. Objectives Describe the home...

In this paper, we show how many fixes are enough to define the territory of two long-lived resident raptors marked by GPS transmitters. To this end, we analyzed high-resolution GPS data from 50 territorial Bonelli's eagles (Aquila fasciata) and 9 territorial Golden eagles (Aquila chrysaetos) equipped with GPS/GSM dataloggers. Our results show that...

Several studies have shown in different organisms how their movements can be fitted to different patterns to optimize search of food resources. According to abundance and availability of resources, different strategies will be optimal, such as Lévy and Brownian random search. We analyze the movement patterns of four species of migratory raptors wit...

To develop effective conservation strategies for migratory birds, it is essential to understand the ecology of a species at each biological phase, including its wintering (or non-breeding) season. For the red kite (Milvus milvus), an endangered raptor from the Western Palearctic, its wintering ecology is little known. We tagged 44 red kites using G...

Jaguars (Panthera onca) are the largest felids in America, mainly threatened by habitat and prey density loss and hunting. Jaguars are mainly nocturnal predators that need large portions of suitable habitat with abundant prey populations. The aim of this work was to assess both jaguar and prey activity patterns, their relations and to understand if...

Red Kite shows a great variability in its migration strategies: most individuals in north-eastern Europe are migrants, but there is also a growing number of sedentary individuals. Here, we tagged 49 Red Kites wintering in Spain with GPS/satellite transmitters between 2013 and 2020 to study the autumn and spring migration between the breeding or sum...

Red Kite shows a great variability in its migration strategies: most individuals in northeastern Europe are migrants, but there is also a growing number of sedentary individuals. Here, we tagged 49 Red Kites wintering in Spain with GPS/satellite transmitters between 2013 and 2020 to study the autumn and spring migration between the breeding or summ...

Physiology can either be a product of or affect the behavior and ecology of individual animals. Blood plasma chemistry contains many components that are indicative of several aspects of a bird’s physiological state at the time of sampling. Plasma chemistry is routinely used in clinical settings. However, despite its potential application in ecologi...

1. Long-distance migrations are among the most physically demanding feats animals perform. Understanding the potential costs and benefits of such behaviour is a fundamental question in ecology and evolution. A hypothetical cost of migration should be outweighed by higher productivity and/or higher annual survival, but few studies on migratory speci...

In species that live in sympatry, some dimensions of their ecological niche can overlap, but coexistence is possible thanks to segregation strategies, being the differential use of space and time one of the most frequent. Through a pioneer study in North-West Africa based on a camera-trapping survey, we studied ecology features of a carnivores’ com...

Cutting-edge technologies are extremely useful to develop new workflows in studying ecological data, particularly to understand animal behaviour and movement trajectories at the individual level. Although parental care is a well-studied phenomenon, most studies have been focused on direct observational or video recording data, as well as experiment...

Abstract Our research is the most comprehensive study of jaguar behavior ecology in Mexico. By analyzing and describing the movements and use of the space, as well as the interactions among individual jaguars, we can better understand their behavioral differences, habitat use, and home range. This type of information is critical for the development...

MIGRATION AND SPATIAL ECOLOGY OF THE SPANISH POPULATIONS OF ELEONORA’S FALCON The Eleonora’s falcon (Falco eleonorae) is an endemic raptor of the Mediterranean ecoregion: all its colonies are located on Mediterranean islands (the great majority in Greece), except for some on the Atlantic coast of Morocco and the Canary Islands. It is a polymorphic...

Pleistocene climate change impacted entire ecosystems throughout the world. In the northern hemisphere, the distribution of Arctic species expanded during glacial periods, while more temperate and mesic species contracted into climatic refugia, where isolation drove genetic divergence. Cycles of local cooling and warming in the Sahara region of nor...

Timing of activity can reveal an organism's efforts to optimize foraging either by minimizing energy loss through passive movement or by maximizing energetic gain through foraging. Here, we assess whether signals of either of these strategies are detectable in the timing of activity of daily, local movements by birds. We compare the similarities of...

https://www.evolutionary-ecology.com/issues/forthcoming/ar3207.pdf Objective: We examine the different pressures that lead to the occurrence of new species and thus to their phylogenies. From the point of view of evolutionary ecology, we seek to examine — in addition to the phylogenetic relationships of different lineages — the evolutionary pressu...

Abstract Background The loss of traditional agropastoral systems, with the consequent reduction of foraging habitats and prey availability, is one of the main causes for the fast decline of Lesser Kestrel (Falco naumanni). To promote the conservation of the Lesser Kestrel and their habitats, here we studied the foraging activities patterns of this...

Decision-making in protected areas is often difficult due to an unclear definition of management objectives and indicators for their monitoring. This is frequently related to the coexistence of systems of protected areas at national and regional levels for which management objectives are ambiguous or that are not directly related to protected areas...

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 and for identifying environmental drivers of population dynamics acting at diffe...

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 large telemetry dataset on the globally endangered Egyptian Vulture Neophron percnopterus...

Se analiza la distribución y en algunos casos abundancia de los grandes depredadores a nivel mundial, así como 3 de estos grandes depredadores en México y algunos temas como etnobiología, y el papel de los zoos en la conservación

Aim Animal movement is an important determinant of individual survival, population dynamics and ecosystem structure and function. Nonetheless, it is still unclear how local movements are related to resource availability and the spatial arrangement of resources. Using resident bird species and migratory bird species outside the migratory period, we...

Human-wildlife conflicts are the object of raising concern in conservation biology. People living in urban areas are rapidly increasing worldwide and consequently the temporal pattern of occupation of natural areas for recreation is changing as well, resulting in an ever-increasing concentration of people during weekends and holidays. This is parti...

Background A study on the Whiskered Tern Chlidonias hybrida was carried out between 2002 and 2009 in wetlands of eastern Spain to evaluate how water level fluctuation affects its reproductive success (hatching, fledgling and breeding success). This species is catalogued as Vulnerable in Spain and has an unfavorable conservation status in Europe. M...

Conservation of migratory species faces the challenge of understanding the ecological requirements of individuals living in two geographically separated regions. In some cases, the entire population of widely distributed species congregates at relatively small wintering areas and hence, these areas become a priority for the species’ conservation. S...

The movement ecology of Harpy Eagles (Harpia harpyja) is poorly known due to the difficulty observing this species. We studied the movements of two juvenile Harpy Eagles before and during dispersal using GPS satellite telemetry in the Reserva de Producción Faunística Cuyabeno, Ecuador. Both eagles were tagged at their respective nest tree. For each...

The Horned Guan (Oreophasis derbianus) is endemic to humid montane forests of southern Mexico and Guatemala. This species is considered endangered because of their small populations, the loss and fragmentation of habitat, illegal trade, and overexploitation by subsistence hunters. We update information about the species' diet and foraging behavior...

This publication analyses the ecology of the movement of the Booted Eagle (Aquila pennata) throughout its annual cycle: breeding and wintering seasons and both migrations in between these areas. This is the second Migra program monograph, with the aims to understand the movements and migration of Spanish Booted Eagles. Migra program is been develop...

Data has been collected mainly through remote monitoring in Spain and Africa during the last decade. Most of the data comes from the Migra program of SEO/BirdLife, although some data from bird banding and tagging with conventional radio-tracking was used. For the study of spatial ecology and movements of the Booted Eagle, 21 birds were captured a...

Contacts across the Strait of Gibraltar in the Pleistocene have been studied in different research papers, which have demonstrated that this apparent barrier has been permeable to human and fauna movements in both directions. Our study, based on the genetic analysis of wild boar (Sus scrofa), suggests that there has been contact between Africa and...
