Thesis
Full-text available
Human activities transformed virtually all landscapes worldwide to fulfil their basic needs (e.g., resource extraction, agriculture or leisure activities). By doing so, they also affect species inhabiting these human-dominated landscapes. Due to their historical link to human activities, apex predators, especially vultures, are especially vulnerabl...
Preprint
Full-text available
Partial migration is one of the most widespread migratory strategies among taxa. Investigating the trade-off between environmental/social factors-fitness and energetic consequences is essential to understanding the coexistence of migratory and resident behaviours. Here, we compiled eld monitoring data of wintering population size and telemetry data...
Article
Full-text available
Carrion production is one of the most crucial yet neglected and understudied processes in food webs and ecosystems. In this study, we performed a large-scale estimation of the maximum potential production and spatial distribution of ungulate carrion biomass from five major sources in penin-sular Spain, both anthropogenic (livestock, big game huntin...
Article
Full-text available
Anthropized landscapes are characterized by various human activities related to resource extraction, recreational activities, and urbanization, among others. Conservation of species living in such landscapes is challenging due to the lack of compatibility between wildlife and human needs, which can create win-lose scenarios for target species. Ther...
Article
Full-text available
Natal dispersal, the movement between the birth and the first breeding site, has been rarely studied in long-lived territorial birds with a long-lasting pre-breeding stage. Here we benefited from the long-term monitoring programs of six populations of Egyptian vultures ( Neophron percnopterus ) from Spain and France to study how the rearing environ...
Article
Full-text available
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 Partial migration, whereby some individuals migrate and some do not, is relatively common and widespread among animals. Switching between migration tactics (from migratory to resident or vice versa) occurs at individual and population levels. Here, we describe for the first time the movement ecology of the largest wintering population of E...
Article
Capsule: In Egyptian Vultures Neophron percnopterus, both sexes invested similar parental effort throughout the breeding period. However, there was variation in the degree of intensity of parental care during some stages of the breeding period, suggesting that sex-role specialization exists for some activities. Aims: To quantify parental care behav...
Article
Full-text available
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...
Article
To properly use vocalizations for the estimation of owl population size, it is important to identify how environmental factors affect owl calling behaviour. Here, we analyze how intrinsic and extrinsic factors modify vocal activity of Tawny Owls Strix aluco in two areas of Northern Spain. From March 2013 to May 2015, we radio‐tracked 20 Tawny Owls...
Article
Full-text available
We monitored Peregrine Falcon (Falco peregrinus) population in Bizkaia, Northern Spain, during two decades (1998-2017). Our population increased from 34 to 47 territorial pairs, as did other European populations until the first years of the 21 st century, and then declined until 34 territorial pairs in 2017. The combination of catastrophic events (...
Article
Anthropogenic activities are one of the main threats to species living in human‐dominated landscapes and can promote behavioral changes in birds. This paper presents a novel approach to test how a migratory species responds to habitat alterations occurring in nesting territories during winter, when the species is absent. From 2000 to 2016, we colla...

Moult is one of the three major events in the annual cycle of birds. However, contrary to breeding and migration, only a relatively minor number of studies have been carried out on this topic. This is particularly the case with the large group of birds of prey and is partly a consequence of a general lack of appreciation of the relevance of moult to the vital cycle of species. This factor is exacerbated by the difficulty in obtaining large enough sample sizes in this group, since some species are scarce and birds of prey are almost always difficult to trap. During the last two decades we have been working with raptors and owls in order to improve our knowledge about moult patterns and consequences in biology, ecology and behaviour of our species. We work with almost all Spanish birds of prey and we are trying to complete our database for each species in order to publish moult patterns and related topics. In this time we have published some articles about several species (i.e., Eurasian Sparrowhawk, Common Buzzard, Griffon Vulture, Bearded Vulture) and others in which we also show moult patterns (i.e., Goshawk, Peregrine Falcon). Moreover, we published a book about owls that was over in few weeks and now is available online (http://icarus.es/libros-icarus-estudios-medioambientales/rapaces-nocturnas/). Finally, we also develop a blog (http://depredadoresdebizkaia.blogspot.com.es/) to make the moult easier to understand (in Spanish), where lector can find (by now) pictures and figures related to moult, ageing and gender determination of Common Buzzards, Eurasian Sparrowhawks and Griffon Vultures.

The adaptation to humanized landscapes by determinate species obligate them to adopt different strategies across space and time.Both urbanization and human population growing comprisses diverse impacts on philopatric species and cause a wide range of effects which could be measured by different ecological methods (for instance population dynamics, breeding behaviour, habitat use,physiology, animal movement among others).
