From August to December, thousands of Black-necked Grebes Podiceps nigricollis concentrate during the flightless moult period in salt ponds in the Odiel Marshes, southern Spain, where they feed on the brine shrimp Artemia parthenogenetica. We pr[...]

Carotenoid-based plumage ornaments have the potential to signal individual condition and health in many species of birds. However, very little is known about the function of red plumage in woodpeckers. We assessed whether the red cap displayed b[...]

With increasing pressures on land for human use, it is important to identify the habitat requirements of key species, not just in terms of a correlation with a given habitat feature, but also the relationship between species presence and its cov[...]

The Europe-wide decline in the populations and diversity of farmland birds has not been stopped despite dedicated conservation efforts such as agri-environment schemes (AES). The main reason for the lack of success of AES is considered to be the[...]

When different populations of the same bird species share non-breeding habitats, competition for food may promote resource partitioning. We studied food choice by resident and migratory Blackcaps Sylvia atricapilla in sympatric wintering grounds[...]

Knowledge of the rate, distance and direction of dispersal within and among breeding areas is required to understand and predict demographic and genetic connectivity and resulting population and evolutionary dynamics. However dispersal rates, an[...]

By altering its flight altitude, a bird can change the atmospheric conditions it experiences during migration. Although many factors may influence a bird's choice of altitude, wind is generally accepted as being the most influential. However, th[...]

Egg development time in the Zebra Finch Taeniopygia guttata varies with laying order and clutch size
Simon C. Griffith, Auteur ;
Amanda J. Gilby, Auteur
As female birds are able to lay no more than a single egg each day, in those species producing larger clutches the first laid eggs may get a developmental head-start over later eggs in the clutch. All other things being equal, the differential p[...]

We studied nesting habitat selection of the endangered non-migratory Osprey Pandion haliaetus population of the Canary Islands and evaluated the effect of human expansion in recent decades. Compared with randomly selected potential nest-sites, O[...]

Clutch size varies among individuals in most bird species. A widespread assumption is that such variation results from variable timing in the disruption of ovarian follicular growth that brings, with a few days' lag, egg-laying to an end. Curren[...]

European Wrynecks Jynx torquilla torquilla have generally been considered to be long-distance Palaearctic-African migrants that spend the non-breeding season in Sahelian Africa, where they have been reported regularly. Results from tracking indi[...]

Carrion consumption patterns in vertebrate scavenger communities may be influenced by several interacting factors. We assessed the effects of the number of scavenger species and the presence of obligate scavengers (vultures) on carcass detection[...]

Sex-related variation in survival is common in birds and, as it influences effective population size and population growth, is important for conservation and species management. Here we assessed incubation behaviour and sex-related survival in a[...]

The begging behaviour of nestlings is part of a communication system by which nestlings solicit food from their parents. In the case of brood parasitic species, nestlings in the nests of host species could achieve appropriate begging calls throu[...]

To assess whether relative clutch mass (RCM) in Anseriformes (wildfowl or waterfowl) is constrained by body shape, principal components (PCs) of size-adjusted measurements of five major skeletal elements of adult males and females of 60 species [...]
