The phenotype-linked fertility hypothesis (PLFH) proposes that both sexual ornaments and sperm traits are phenotypically plastic and co-affected by environmental factors through individual condition, resulting in a positive correlation between o[...]

Hybridization between Atlapetes brushfinches has been scarcely documented across the 28 species of the genus. An unusual Atlapetes was observed and collected in the foothills of the southeast Andes of Colombia. We analysed plumage, morphometrics[...]

Island populations are frequently smaller than continental populations, have lower genetic diversity, are more inbred and show genetic differentiation from the mainland ones. However, sufficient numbers of immigrants may reduce the differentiati[...]

Vivid plumage colors are some of the best examples of elaborate trait evolution resulting from sexual selection. Bird feathers often contain high concentrations of pigment or intricate microstructures for reflecting light at distal feather tips,[...]

Collision with wind turbines is an increasing conservation concern for migratory birds that are already facing many threats. A proliferation of proposals for single-turbine wind projects on U.S. Atlantic beaches where piping plovers nest poses a[...]

In a mountain context, the forest-shrub ecotone is an area of high biodiversity. Relatively little is known about the habitat requirements of birds in this habitat, yet it is facing potential threats from changes in grazing practices and climate[...]

The Chinese Penduline Tit (Remiz consobrinus) is a small passerine that breeds in Northeast Asia. Despite its common appearance and its high encounter rate, the breeding biology of this species has remained largely unknown. In this paper, we des[...]

The acoustic adaptation hypothesis (AAH) states that animals communicating acoustically adapt their vocalizations to the local conditions to optimize signal transmission. We tested select predictions of the AAH by studying the relationships betw[...]

Phenotypic differentiation is common among populations that have large geographic distributions. One proposed mechanism driving phenotype divergence is sexual selection, which predicts that trait differences among closely related populations are[...]

The present day distribution and spatial genetic diversity of Mesoamerican biota reflect a long history of responses to complex topography, geological history and climate changes. The hummingbird Colibri thalassinus thalassinus is distributed in[...]

Rhynochetos orarius has been described from Holocene fossils as the sister species of the smaller extant Kagu Rhynochetos jubatus, a bird endemic to New Caledonia. However, we argue that there has never been evidence justifying the description o[...]

Numerous birds use bryophytes as nest construction material but the species used and their biology remain largely unknown. Therefore, questions related to the selectivity of birds in their bryophyte use, and why they use/ignore particular specie[...]

The immune system is a particularly costly activity that competes with other functions of an organism, such as reproduction, although research is lacking on the importance of environmental factors for the parental investment in offspring immunit[...]

Although interspecific competition is suggested to be one of the major forces dictating community structure, interspecific interference competition for nest sites in birds has been reported mainly from observational studies. Here, we asked wheth[...]

Methods to assess environmental pollution and stress responses in birds with scarcely invasive or non-invasive sampling are highly sought after in ecology and conservation. For several years now, feathers have been promoted as non-invasive tools[...]

Red-necked Grebe (RNG) breeding numbers have been declining in parts of Europe for more than 10 years. We have examined population trends and estimated, for the first time, survival rates of RNGs in a population in eastern Poland in order to exp[...]

Sperm competition, the competition among rival males’ sperm for the fertilization of a given female’s set of ova, is a powerful selective force shaping male reproductive traits such as sperm performance. Sperm morphology, the size and shape of t[...]

While sexual signalling often compromises camouflage, some traits, including avian barred plumage, have been suggested to function simultaneously in camouflage and sexual signalling. Compared to coloration without pigmentation patterns, visual p[...]
