Plumage odors may function as chemical defenses against ectoparasites in birds. We tested this hypothesis for crested auklets (Aethia cristatella), a species of colonial seabird that emits a very strong citrus-like odor from its plumage. This od[...]

The Okinawa woodpecker Sapheopipo noguchii is the rarest extant woodpecker species. The monotypic genus Sapheopipo was considered to be a representative of an old lineage of woodpeckers that led to the Eurasian genera Picus and the Blythipicus-G[...]

We choose the European Nuthatch (Sitta europaea), an extremely socially monogamous passerine species, to investigate the breeding biology and frequency of extra-pair activities of females. Breeding individuals live in strong pair bonds for their[...]

For birds that breed in large colonies, the overall area occupied by the colony generally comprises several sub-areas that differ in physical and social features such as vegetation and breeding density. Birds arriving at a breeding colony select[...]

Several woodpecker species feed on phloem-sap flowing from pecked trees. We report sap consumption by the magellanic woodpecker (Campephilus magellanicus) inhabiting beech (Nothofagus) forests of Tierra del Fuego island (Chile). Magellanic woodp[...]

Habitat use by the sedge warbler Acrocephalus schoenobaenus, reed warbler A. scirpaceus and marsh warbler A. palustris was studied during 1998-2000 in an intensively cultivated agricultural landscape in western Poland. The birds occupied mid-fie[...]

Body mass changes in wintering ducks have been considered as the consequence of their "wintering strategy", i.e. low mass after autumn migration, active foraging leading to body mass restoration, then pairing leading to low body mass again. This[...]

Allofeeding is a common social display among adult Arabian babblers (Turdoides squamiceps). The sociology and rates of allofeeding were studied with a tame population of babblers at the Shezaf Nature Reserve in the Rift Valley, Israel. Allofeedi[...]

Parental behaviour and nest site are supposed to affect nest predation in birds. Few nest visits and high nest attentiveness are assumed to lead to low predation rates. Poorly concealed nests are thought to be more likely to be preyed upon than [...]

The pattern of phenotypic and molecular variation within the polytypic olivaceous warbler H. pallida was examined. This species is distributed in the southern parts of the western Palaearctic, central Asia and in the arid parts of northern Afric[...]

The number of primary feathers in a bird's wing has been used as a systematic character since the first half of the nineteenth century. During the years, though, the definition of which feathers to count as a primary has changed and today the sp[...]

We investigated chick development and feeding rate in the neotropic cormorant, Phalacrocorax brasilianus, in a colony in Central Chile. The year of our study was characterized by relatively good foraging conditions. Brood sizes varied from two t[...]
