The application of modern spectrometry to the study of avian colour variability has revealed ignored patterns of colour variation such as male-biased sexual dichromatism and seasonal variability in the plumage. However, the variation in the achr[...]

Geographic variation in male bird songs has been studied extensively, but there have been few investigations of geographic variation in female songs or sex differences in patterns of geographic variation. We compared patterns of variation in mal[...]

Satin bowerbirds Ptilonorhynchus violaceus have an elaborate multi-component sexual display, some components of which have been extensively studied. We describe a relatively unstudied component of this display, bower painting, and birds' respons[...]

Island populations harbour a comparatively species-poor pathogen community, often resulting in naive host species that experience compromised immunity when faced with novel diseases. Over 95% of the Galapagos avifauna have survived 400 years of [...]

Where there is seasonal disparity among opportunities, the season with those in shortest supply is most likely to limit populations. Among migrant birds that travel between different breeding and winter ranges, any of breeding, migratory or wint[...]

Fault bars are common stress-induced feather abnormalities that could produce feather damage thus reducing flight performance. For that reason, it has been hypothesized that birds may have evolved adaptive strategies that reduce the costs of fau[...]

Body mass of Brunnich's guillemots Uria lomvia breeding at Coats Island, Canada, was measured during incubation and chick-rearing in 1988-2001. In most years, mass increased during incubation and fell after hatching, leveling off by the time chi[...]

Many large marine vertebrates are today threatened by human activities and it is therefore crucial to obtain information on their distribution and behaviour at sea. In particular little is known about the time necessary for juveniles to acquire [...]

From 1976 to 1997 passerines were mist-netted and ringed on the island of Christianso, in the Baltic Sea. Here we present analyses of phenological changes (i.e. time of arrival) for 25 species based on the entire populations of mist-netted songb[...]

Mobbing is a widespread anti-predator strategy in birds, and predators are generally expected to avoid mobbing. For example, observational studies suggest that the cryptic roosting behaviour of nocturnal predators, such as many owls, may be a st[...]

Social factors, such as the duration of territorial occupancy or of time paired with a mate can affect the rate at which individual birds sing. This study examined the influence of duration of pair-bond and territory occupancy as well as date on[...]

Hybridization in birds is a widely acknowledged phenomenon. It often occurs when one species is absent or rare which leads to mixed pairings between different species (Hubb's principle). However, Hubb's principle cannot explain hybridization in [...]

Patterns of feather wear in birds captured in spring have traditionally been analysed to describe the extent of winter moult in long-distance migrants. However, the interpretation of feather wear may be rendered extremely difficult due to long m[...]

The genetic mating system is known for only a few species of owls. Most of them are genetically monogamous. The Lanyu scops owl Otus elegans botelensis breeds in high density in the forests of Lanyu (Orchid Island), southeast of Taiwan. Because [...]

Offspring survival probability usually decreases with hatching order, especially in species with brood reduction. Brood reduction in combination with a sex difference in embryonic period (the time between laying and hatching of an egg) can poten[...]

Carotenoids are a large group of biochemicals, with similar properties, synthesised by bacteria, fungi, algae and plants. Vertebrates obtain these biologically active pigments through the diet, and they are a disproportionately common component [...]

This study was designed to determine the spring, summer, autumn, and early winter distribution, migration routes, and timing of migration of the Atlantic population of Steller's eiders Polysticta stelleri. Satellite transmitters were implanted i[...]
