Wing-spreading of cormorants (Phalacrocoracidae) is a characteristic and enigmatic aspect of their behavioural repertoire. It has been suggested to have a range of functions including wing-drying, food-warming, and social signalling of foraging [...]

Extra-pair paternity is common in many socially monogamous bird species. Increasing evidence suggests that extra-pair copulations are female-driven, but benefits for females mating outside social pair-bonds are still poorly understood. The most [...]

Melanins are common feather pigments that contribute to signaling and crypsis. Melanins may also help feathers resist feather-degrading bacteria (FDB). Two recent studies (Goldstein et al. 2004, Grande et al. 2004) tested the resistance of melan[...]

The practice of mummification by the ancient Egyptians is well known. However, it is less widely known that the ancient Egyptians also mummified animals, including birds, for religious and ceremonial reasons. Few radiographic descriptions of avi[...]

High rates of extra-pair paternity (EPP) can be relatively common in passerines whereas low rates or absence of EPP are often associated with taxa that are long-lived and exhibit obligatory paternal care. We examined EPP in an under-represented [...]

Despite a long history of anatomical studies in birds, the genitalia of most avian species remain undescribed. Birds are the only vertebrate taxon with internal fertilization where an intromittent phallus has been lost in most species. Studying [...]

To assess regression models for lipid and lean body mass in small birds, we recorded live body mass +/- 0.1 g, total body electrical conductivity (TOBEC; from "third generation" TOBEC machine EM-SCAN (R) SA-3000) or E-Value, visual fat score (Vi[...]

We describe an unknown mode of solar-assisted egg development in the crab plover Dromas ardeola, a shorebird that breeds in self-excavated burrows. The insulating properties of the nest burrow and the intense solar radiation allowed egg developm[...]

Incubation was for a long time considered to be a period of decreased activity and low cost for parents. It was therefore ignored as a potential factor affecting life-history trade-offs in birds. Lately this view has started to change, and studi[...]

We examined the occurrence of six species of meadow birds (four wader species and two songbird species) in relation to the distance to the nest location of an avian predator (three species). We related our findings to the degree of openness of t[...]
