Estimates of reproductive success are essential to understand life-history strategies, yet tropical species remain under-studied relative to their temperate counterparts. Here, we report nest survival probabilities for two manakin species (Pipri[...]

The colouration exhibited by nestling birds is generally cryptic, but in some species it has a conspicuous appearance. The adaptive function of these nestling displays is poorly known, especially in altricial species. We performed an experimenta[...]

Decline of migrant wader populations worldwide implies that their demography may be affected by phenomena occurring in a large geographical scale. Knowledge about vital rates affecting population growth and viability helps in finding the process[...]

Many avian species are negatively impacted by urbanization, but other species survive and prosper in urbanized areas. One factor potentially contributing to the success of some species in urban areas is the reduced presence of predators or paras[...]

Although both repertoire sharing and individual variation have been studied widely in male solo song, few studies have investigated these aspects of song in a species that performs complex duets. This study examined song repertoires of both male[...]

In vertebrates, males are often more parasitised than conspecific females. This bias in parasitism might result from sex differences in parasite exposure and/or susceptibility to infection. Such information is important for testing hypotheses ab[...]

Wild bird feeding is one of the most common forms of human-wildlife interactions in the Western world. Originally a practice providing nutritional assistance to over-wintering birds, especially in more northern latitudes, birds throughout the ci[...]

The Chatham Island taiko Pterodroma magentae (tchaik) is one of the World's most endangered seabirds with a population size of between 120-150 individuals that includes only 8-15 breeding pairs. Molecular techniques were used to identify the sex[...]

When females mate multiply, sperm competition can generate strong selection for traits that provide males with a fertilisation advantage. This study examined the cloacal tip, a unique morphological structure of males that appears to be associate[...]

Dispersal is a key parameter in evolutionary, demographic and conservation theory, but the factors influencing dispersal between populations are rarely known, and the contribution of immigrants to population stability remains uncertain. Using di[...]

In passerine species with frequent extrapair mating, young (second calendar year) males often have a lower fertilization success than older (after second calendar year) males. This pattern might be explained by male- or female-driven mechanisms,[...]

Genetic variation in the common bush-tanager Chlorospingus ophthalmicus complex in Mesoamerica was studied. An 800-bp mitochondrial DNA fragment, including a portion of COII, full tRNA-Lys, ATP8, and partial ATP6, was sequenced and analyzed for [...]

Identifying the natal origins of brood parasites is a major challenge that usually requires labor-intensive searching for nests of host species. Stable isotope analysis of feathers and other body tissues of parasitic young could be a possible to[...]

Many birds acquire carotenoid pigments from foods and deposit these pigments into feathers and bare-parts to become sexually attractive, but little work has been done on the interindividual and temporal variability in the types and amounts of ca[...]
