Understanding the extent of overlap between life-history stages is fundamental to understanding full-life cycle biology, especially for migratory species. Testosterone levels vary throughout the annual cycle in seasonally reproducing vertebrates[...]

Contemporary climate change has been linked to widespread changes in phenology and in the geographic distribution of species. Based on Bergmann’s rule, body sizes of birds have been predicted to decline as global temperatures increase. We examin[...]

Long-lived seabirds are good models to study the mechanisms that mediate the parent–offspring interactions. Contrary to studies under natural conditions, experimental manipulations allow us to assess the birds’ reactions in a short time period. [...]

Diverse historical and ecological factors determine and drive diversification of vertebrate lineages. Historical factors (e.g., orogenic movements) are expected to act on coarser spatial and temporal scales than contemporary ecological factors ([...]

Demographic parameters in wild populations are expected to be shaped by individual covariates and environmental variability. Thus, the understanding of the effects of age and/or environmental conditions on variability in vital rates is of specia[...]

Many birds exhibit territoriality, which is vital for obtaining resources for survival. Non-migratory birds maintain larger territories in winter than during reproduction, but the degree of their fidelity to these winter home ranges is less well[...]

Blue-winged Teal (Anas discors) initiate southward migration from their North American breeding grounds in late summer, making trans-Gulf flights to overwinter in South America. As such, this species displays a fall migratory pattern unique amon[...]

Diagnosing distinct evolutionary taxa requires careful assessment of genetic, morphological, ecological, and behavioral variation within and among populations. In this study, data on phenotype (mensural and plumage coloration), genotype (mitocho[...]

Common Crossbill (Loxia curvirostra) populations are dependent on specific key conifer species for their primary food supply, but many of these conifers standardly show irregular cone crop production. Consequently, the species has evolved a noma[...]

Intraspecific geographic variation in morphology is common in animals along geographic or climatic clines. Local ecological factors are likely to act simultaneously at smaller spatial scales, but have hardly been contrasted with wide-ranging pre[...]

Migratory birds face population declines attributed to habitat loss and modification in the wintering grounds, which may influence body condition, time of arrival to breeding grounds, and future reproductive opportunities. Despite this, very lit[...]

Breeding performance of many vertebrate species is known to improve over the early stages of the life cycle, which has been commonly attributed to the progressive improvement in competences and increasing investment in reproduction. While there [...]

Few cases of adoption have been reported in solitary breeding raptors, and in owls adoption has only been reported in two species. Here we report four cases of brood-switching of juvenile Tengmalm’s Owls (Aegolius funereus), recorded during and [...]

Distinctive individual vocalizations are advantageous in several social contexts. Both genetic and environmental effects are responsible for this phenomenon resulting in different frequencies and time domains of sounds in birds. This individuali[...]

Direct observational studies are needed to address dietary adjustment in species breeding in isolated non-forest habitat islands with respect to the energy demands of growing nestlings and breeding patch size. Using new dietary records determine[...]

Biparental care is the dominant (81 %) form of parental care in birds. The degree of sexual selection and the resulting mating system and parental care type have been determined, in many cases, by inference from external characters of sexual dim[...]

A better understanding of factors affecting population change is needed to explain declines of long-distance migrants. As juvenile survival is generally an important determinant of population dynamics, assessing whether juvenile survival is prim[...]

Avian nests function to provide a safe environment for parents, eggs and nestlings. Positive associations between nest size and other components of breeding performance are expected in two conditions. First, larger nests protect nest occupants b[...]

The Hazel Grouse (Tetrastes bonasia) is a cryptic forest-obligate bird species with special habitat requirements, including structured mixed forests at the local scale and good connectivity at the landscape level. These conditions are rarely met[...]

Despite recent advances in avian tracking technology, archival devices still present several limitations. Traditional ring recoveries provide a complementary method for studying migratory movements, particularly for cohorts of birds with a low r[...]
