Several ectoparasites parasitise nestlings decreasing their body condition, growth and
survival. To minimise any loss of fitness due to ectoparasites, birds have developed a wide …

Adaptation to insular environments often arises from changes and innovations in feeding
behaviour allowing expanded foraging habits and an increased niche breadth. These shifts …

Habitat loss and degradation are frequently associated with negative effects on biodiversity
in natural and semi-natural landscapes. Innovative spatio-temporal modelling tools may be …

Nest‐site limitation may have different implications in the spatial distribution of breeding
pairs depending on the availability of suitable habitat and the types of nest‐sites. Distribution …

The study of the mechanisms involved in phenotypic adaptations or plasticity to
environmental stressors may serve to evaluate contemporary ecological and evolutionary …

Differences in competitive abilities of siblings in birds can be caused by a combination of
hatching asynchrony and intra-clutch variation in egg quality. However, very little is known …

The onset of incubation before the end of laying imposes asynchrony at hatching and,
therefore, a size hierarchy in the brood. It has been argued that hatching asynchrony might …

Capsule Red-billed Choughs showed strict mate and high nest-site fidelity. Changes of mate
or nesting site were recorded only in cases of widowhood or collapse of the nesting sites …

El anillamiento científico de aves es una técnica de estudio con más de un siglo de historia
que, probablemente, ha contribuido como ninguna otra metodología al conocimiento de la …

Factors determining nest predation are often multiple and spatiotemporally variable. We
evaluated the relative importance of nest placement on predation risk of red-billed choughs …
