We measured deuterium isotope ratios (delta D(f)) in primary feathers to distinguish first-year from older Pectoral Sandpipers Calidris melanotos captured in Barrow, Alaska, during the breeding season. delta D(f) showed a distinct bimodal distri[...]

The Whinchat Saxicola rubetra is an Afro-Palaearctic migrant undergoing widespread population decline. Whinchats winter in West Africa but there are almost no data on their habitat use and behaviour there that may help to explain the cause of th[...]

Birds breeding on islands often exhibit lower rates of extrapair paternity than their mainland counterparts, perhaps explained by low genetic variation, slower life histories and reduced sexual selection in island populations. Extrapair paternit[...]

We review the conservation issues facing migratory shorebird populations that breed in temperate regions and use wetlands in the non-breeding season. Shorebirds are excellent model organisms for understanding ecological, behavioural and evolutio[...]

To understand the biology of organisms it is important to take into account the evolutionary forces that have acted on their constituent populations. Neutral genetic variation is often assumed to reflect variation in quantitative traits under se[...]

Breeding is energetically expensive and individuals face a trade-off between current and future breeding investment. Due to their production of large eggs, female birds are thought to have substantially higher initial energetic investments than [...]

Both intrinsic and extrinsic factors recorded at individual nests can predict offspring fitness and survival but few studies have examined these effects in the tropics. We recorded nestling survival, post-fledging survival and age at first retur[...]

Differing reproductive effort, individual qualities and local environmental conditions can lead to uneven mortality risk among individuals within populations and may result in survival differences according to age and sex. Identification of fact[...]

Coastal seagrasses are declining at increasing rates worldwide, forcing herbivores previously reliant on these habitats to abandon them in search of alternative ways to fulfil their daily energy budgets. After two decades of declining seagrass a[...]

The plasma metabolites triglycerides (TRIG) and beta-hydroxybutyrate (BUTY) are used as indices of nutritional condition in migrating birds during refuelling and can provide a measure of relative fattening rates in individual birds. Because non-[...]

Measuring the food left in experimental trays when study organisms cease feeding on them [so-called giving-up densities (GUDs)] is an accepted technique for assessing predation risk and disturbance. However, in natural settings, accessibility an[...]

The monotypic Stone Partridge Ptilopachus petrosus (Galliformes: Phasianidae), restricted to arid rocky areas of the northern savanna belt including the Sahel on the southern border of the Sahara Desert, is a taxonomic enigma. Historically, it h[...]

With only a single extant representative, endemic to the Tuamotu Archipelago, the Polynesian sandpipers (Aechmorhynchus and Prosobonia) may have had a larger distribution in Eastern Polynesia in the past, with four endemic taxa. Although these a[...]

Selection pressures due to parasitism play an important role in driving the evolution of life history traits of birds in general and of behaviour at the nest in particular. Eggshell bacterial load has been shown to predict hatching failure (i.e.[...]

It is well documented that irruptive and nomadic migrants move in response to resources that are distributed unpredictably in space, time or both. Increasing evidence, however, suggests that irruptive and nomadic species may use seasonal timing [...]
