Although male age has often been found to predict success in gaining extra-pair paternity, it is unclear whether this gain is associated with an individuals success in avoiding cuckoldry. We examined the relationship between male age and both wi[...]

To understand population dynamics it is necessary to understand vital rates, which may be affected by a wide range of factors including environmental variables such as weather. Weather conditions can affect birds vital rates directly through inc[...]

In some bird species, the survival of chicks hatching later in the season is lower than those hatched earlier due to increased risk of predation and a seasonal decline in feeding conditions. To reduce these risks, it might be advantageous for la[...]

Age-related improvement in reproductive success is widely observed in birds, and the mechanisms by which productivity is enhanced have received considerable attention. However, little is known about how parental age affects the loss of eggs or n[...]

Reevess Pheasant Syrmaticus reevesii is a vulnerable forest bird inhabiting broadleaved habitats dominated by oaks Quercus spp. in central China. Identifying home-ranges and habitat associations is important for understanding the biology of this[...]

Ecological features and conservation requirements of populations at the latitudinal limits of a species geographical range frequently differ from those in other parts of the range. Identifying such differences is key to implementing effective co[...]

Winter body condition may play important roles in the life history of migratory birds, but it is difficult to estimate. We used the growth rate of winter-grown tail feathers of Collared Flycatchers Ficedula albicollis as an indicator of winter b[...]

Anthropogenic habitat change and assisted colonization are promoting range expansions of some widespread species with potential consequences for endemic fauna. The recent colonization of Cyprus by breeding Sardinian Warblers Sylvia melanocephala[...]

We used analyses of stable hydrogen isotope (d2H) measurements in Common Crossbill feathers (d2Hf) to infer the region of origin of Crossbills collected from different irruptions into Britain, Iceland and the Faeroes, comparing these values with[...]

The potential for agri-environment schemes to reverse farmland bird declines is limited for some species by a lack of suitable prescriptions, in particular effective in-field options for species that breed in crops. We assess the provision of al[...]

Recent improvements in satellite tracking, such as the miniaturization of transmitters, have enabled the study of movements of an increasing number of bird species. The Lesser Kestrel Falco naumanni has been the subject of numerous studies but d[...]

After being fed by their parents, Greater Flamingo chicks store food in their crops, which protrude outwards. We allocated the crop profiles of chicks to four categories to assess the relationship between body mass and crop profile variation, an[...]

Several hypotheses have been proposed to account for the adaptive evolution of personality, defined as inter-individual differences in behaviour that are consistent over time and across situations. For instance, the pace-of-life syndrome hypothe[...]

In the arms race between avian brood parasites and their hosts, several adaptations and counter-adaptations have evolved. The most prominent host defence is rejection of parasitic eggs. We experimentally parasitized nests of 10 potential host sp[...]

Parentage studies have shown that alternative reproductive strategies are widespread in many avian taxa that were once thought to be monogamous. Recent anthropogenically mediated habitat change may have disrupted ecological factors, such as bree[...]

Our understanding of the effects of habitat loss on individual performance is limited due to a lack of experimental studies that take the potential genetic and parental effects producing phenotypic variation into consideration. To assess the rel[...]

The way an organism spreads its reproduction over time is defined as a life-history trait, and selection is expected to favour life-history traits associated with the highest fitness return. We use a long-term dataset of 277 life histories to in[...]

Costs of reproduction represent a common life-history trade-off. Critical to understanding these costs in migratory species is the ability to track individuals across successive stages of the annual cycle. We assessed the effects of total number[...]
