Black kite nest decorations are honest signals of individual and territory quality.
Summary The deployment of electronic devices on animals is rapidly expanding and producing leapfrog advances in ecological knowledge. Even though their effects the ecology behaviour marked subjects are potentially important, <10% studies accompanied by an evaluation impact, comprehensive, long‐term assessments have been few. Therefore, there urgent need to test for impacts, especially tags that heavy deployed long time periods, such as satellite transmitters. We 110 individuals a...
Abstract The annual cycle of most animals is structured into discrete stages, such as breeding, migration and dispersal. While there growing appreciation the importance different stages an organism’s for its fitness population dynamics, almost nothing known about if how seasonal effects can change through a species lifespan. Here, we take advantage opportunity offered by long-term satellite/GPS-tracking study reliable method remote death-detection to show that certain both life migratory...
Abstract Assessing mortality factors and survival rates is a cornerstone for the management of threatened harvestable species. Modern tracking technologies allow unprecedented opportunities to monitor individuals years. However, methods employed separate actual deaths from transmitter failures have rarely been validated. Here, we review these previous exploit an intensive satellite‐tagging programme on raptorial black kites Milvus migrans examine through tree models whether any tag‐parameter...
Summary In birds, the steroid hormone corticosterone ( CORT ) is considered a major mediator in number of physiological mechanisms and behaviours critical for regulation an organism's energy balance. However, question whether way which circulating plasma incorporated into feathers actually reflects this regulation, consequently feather ‐F) measures allow to make inferences on past levels energetic demands (also known as allostatic load), remains unclear. While previous studies have yielded...
Large, long-lived species with slow life histories and protracted pre-breeding stages are particularly susceptible to declines extinction, often for unknown causes. Here, we show how demographic modeling of a medium-sized raptor, the Red Kite Milvus milvus, can aid refocus conservation research attention on most likely mechanisms driving its decline. Kites' survival reproduction increased through three sequential 1-2, 3-6, 7-30 yr age, mainly corresponding individuals that dispersing,...
The outcome of social and sexual competition in animals is typically mediated through the expression body traits. Conspicuous characters such as yellow, orange, red colorations skin, scales, feathers are often posited quality-dependent signals, because colors made dietary carotenoids their use for signaling conflicts with health functions. Raptors lack brightly colored but most diurnal species display intense orange yellow hues cere legs. Here we test hypothesis that integument coloration...

Abstract Climate change is increasing the frequency of extreme events, such as droughts or hurricanes, with substantial impacts on human and wildlife communities. Extreme events can affect individuals through two pathways: by altering fitness adults encountering a current extreme, affecting development born during natal largely overlooked process. Here, we show that impact drought an avian predator overrode effect for decades, so were disadvantaged throughout life. Incorporation effects...
Migration research is in rapid expansion and increasingly based on sophisticated satellite-tracking devices subject to constant technological refinement, but still ripe with descriptive studies need of meta-analyses looking for emergent generalisations. In particular, coexistence different frequency location sampling spatial accuracy generates doubts data compatibility, potentially preventing meta-analyses. We used a migratory raptor to: (1) test whether frequencies position subsampling...
Abstract Major histocompatibility complex (MHC) genotyping still remains one of the most challenging issues for evolutionary ecologists. To date, none proposed methods have proven to be perfect, and all provide both important pros cons. Although denaturing capillary electrophoresis has become a popular alternative, allele identification commonly relies upon conformational polymorphisms two single‐stranded DNA molecules at most. Using MHC class II (β chain, exon 2) black kite (Aves:...
Abstract Protected areas are supposed to maintain viable populations of plant and animal taxa shield them from anthropogenic threats, but this role is increasingly under scrutiny. Here, we document the alarming extinction a small falcon, Eurasian hobby Falco subbuteo , in Doñana National Park, an iconic protected area renowned for its rich predator community. Hobbies were originally abundant at 50–60 pairs acted as unique specialist hunters swifts dragonflies. This diet implies niche within...
We examined whether hypothalamic-pituitary-adrenal axis activity in the nestlings of a semialtricial raptor, black kite (Milvus migrans), varied with advancing age, throughout day, and response to number socioecological factors presumed affect allostatic load. Both baseline corticosterone (CORT) titers maximum CORT levels during 30 min handling restraint augmented across all sampled ages, suggesting that nestlings' energetic demands capacity respond perturbations increase progressively...
Top-predators serve as sentinels of ecosystem health due to their sensitivity environmental contamination. However, our understanding on how contaminants affect individual fitness is still scarce, especially for long-lived species. Here, we measured blood concentrations 4 metals (Cd, Cu, Pb, and Zn) one metalloid (As) in black kite (Milvus migrans) adults from Doñana National Park (SW Spain) following a major mine spill. Besides temporal variation (1998-2001) metal As concentrations, tested...
