Moulting strategies in birds have evolved to avoid overlap with, or prepare for, other
demanding parts of the annual cycle, such as reproduction or migration. When moulting for …

Life‐history theory postulates that physiological traits, such as energy metabolism, can be
understood in terms of allocation trade‐offs between self‐maintenance and reproduction …

We developed aging criteria for 7 species of manakins (Pipridae) from the Manu Biosphere
Reserve, Peru, based on patterns of plumage maturation and wing-feather replacement …

Despite molting is an important and expensive activity in the life cycle of birds, this process is
poorly known for neotropical species and even less so for species inhabiting urban zones …

la supervivencia de las aves en el largo plazo. Altamente demandante, la expresión y …

The feathers of the wing that power flight in birds (the remiges) are morphologically
constrained by the demands of aerial locomotion, but peculiar morphologies exist in many …
