Body composition of birds is often used to assess in part the "condition" of individuals in the context of their life history and ecology. We describe contemporary non-destructive (non-lethal) techniques that are available for estimating the bod[...]

A literature review showed that most recent conventional dietary studies of Procellariiformes have used otoliths alone to identify fish prey. Using data from a dietary study of Cory's Shearwaters Calonectris diomedea, based on 673 regurgitates f[...]

Molecular analyses support a sister group relationship between the African Cuckoo Finch (Anomalospiza imberbis) and Viduidae (whydahs and indigobirds). This result was interpreted as evidence for a single origin of brood parasitism in Old World [...]

During reproduction, birds are confronted with two requirements: building up their energetic reserves during the activity period, and provisioning the nest. Storing reserves imposes a higher flight cost and a lower hunting efficiency. This confl[...]

Variation in melanin coloration is widespread and often associated with other phenotypic traits. A recent study showed that darker-reddish pheomelanic Barn Owls (Tyto alba) move longer distances between birth and breeding sites. Because this stu[...]

Incubation strategies by birds are central to reproductive success, particularly for species in which only one parent incubates the eggs. Incubating adults must behave in ways that allow them to maintain their own nutritional requirements while [...]

Many migratory birds use a chain of stopover sites to fuel their migration. Under time-minimizing migration, fuelling time and giving-up density at stopovers are predicted to depend on fuelling conditions. Fluctuations in food accessibility like[...]
