Understanding the population dynamics of migratory animals and predicting the consequences of environmental change requires knowing how populations are spatially connected between different periods of the annual cycle. We used stable isotopes to[...]

The energetically challenging periods of molting and breeding are usually temporally separated in temperate birds, but can occur simultaneously in tropical birds, a condition known as moltbreeding overlap. Here, we document great variation in th[...]

Nest visit synchrony, whereby adults coordinate their visits to the nest, has been documented in several species of cooperative breeders. Visit synchrony may reduce nest predation rate or sibling competition, or instead follow from synchronisati[...]

Individuals may be maladapted to novel environments at the species distribution margin. We investigated population dynamics in a marginal habitat where reproduction has been proven poor. Survival, population growth rate (?) and its components, b[...]

Growth bands and fault bars, widespread features of feathers that form during regeneration, have largely been studied independently. Growth bands result from normal regeneration: each pair of dark/light bands forms every 24 h. Fault bars are a r[...]

In dangerous situations, animals learn from experience to anticipate risks during similar subsequent occasions. Mist netting may represent just such a dangerous occasion and may serve as a tool to get insight into whether and how memorizing and [...]

Mothers can adjust the phenotype of their offspring to the local environment through a modification of their egg investment and/or nestling provisioning. However, offspring health may be severely impaired if the conditions experienced by nestlin[...]

Habitat loss and fragmentation is one of the main causes of biodiversity loss. Rare species are generally thought to be more sensitive to habitat fragmentation than common ones as small populations become even smaller. We did a population geneti[...]

Hybridization has presented a challenge for taxonomists and conservation biologists, since hybridizing forms could be stable evolutionary entities or ephemeral forms that are blending together. However, hybrid zones also provide a unique opportu[...]

We examined variation at MHC Class IIB genes in a recently established population of dark-eyed juncos Junco hyemalis in a coastal urban environment in southern California, USA relative to an ancestral-range population from a nearby species-typic[...]
