We studied the return rate, apparent survival, and probability of recapture of the Saffron Finch ( Sicalis flaveola pelzelni ), a thraupid with sexual dichromatism and age-related male feather phenotypes; the second-year males are dull and indistingu

Abstract Extra-pair paternity rates vary markedly across avian taxa, but patterns of variation in this trait have been obscured by a paucity of data on closely related species, especially those spanning broad environmental gradients. Here we compare

Sexually dichromatic birds often show delayed plumage maturation, but second-year (SY) males may or may not be distinguishable from females. In competitive contexts, SY males receive a reduced amount of adult males' aggression, either by mimicking fe

Birds sing mostly to attract partners or to defend territories or resources. In relation to the first function, song can vary with age if older experienced males signal their quality through their vocal output. Regarding the second function, song can

In birds, the selection of nesting sites and mates has a profound influence on the daily interactions of individuals. Both behaviours are energetically costly and time-consuming and can strongly affect the Darwinian fitness of individuals. Using a 12
Thraupidae (Tanagers and allies) show a remarkable array of behaviors, ecologies, morphologies and plumage colors, offering a great opportunity to investigate the evolution of avian mating strategies. We characterize the population genetics and matin

Ecological and physiological factors such as breeding density, breeding synchrony, and adult body condition can all affect extra-pair mating behavior, but the relative importance of these factors may vary among species. White-rumped Swallows (Tachyci

Empirical descriptions of vocal behaviour in avian communication are important in understanding its meaning and role in shaping the social and genetic relationships among individuals in a population. In this study, we provide the first detailed analy

Egg mass production is costly, but hatching from heavier eggs could be beneficial for the nestling's phenotype and fitness. Egg mass could be influenced by proximate causes, like food abundance, female condition, environmental conditions, and/or by u
