The migration route of Red-necked Phalarope populations breeding on North Atlantic islands has been subject to considerable speculation. Geolocator tags were fitted to nine Red-necked Phalaropes breeding in northern Scotland to assess whether th[...]

In many species, naive first-time migrants undertake migration without adults, supposedly on the basis of a simple' vector programme that combines an innate directional preference with a temporal programme that specifies distance. In strongly di[...]

The choice of the moulting habitat is of paramount importance for wing-moulting waterbirds that have to cope with a flightless period of several weeks. However, some species might have more restricted habitat requirements during moult than other[...]

We present the first report of complete overlap of breeding and moult in a shorebird. In southeastern Australia, Hooded Plovers Thinornis rubricollis spend their entire lives on oceanic beaches, where they exhibit biparental care. Population mou[...]

Little is known about how a 70% loss of native forests has affected the genetic connectivity of remnant bird populations in New Zealand. We use the common and widely distributed New Zealand Bellbird Anthornis melanura as an indicator species of [...]

The nature of tree-line habitats in the Andes has long been a contentious topic in the ecological literature. Palynological studies suggest that a combination of anthropogenic and natural processes throughout the Holocene contributed to its pres[...]

The phylogeography and evolutionary history of the long-distance migratory Eurasian Reed Warbler Acrocephalus scirpaceus were analysed using sequence data from the mitochondrial DNA COI gene of 405 individuals and cyt b sequences from a subset o[...]

Uncovering the mechanisms involved in the decline of long-distance migrants remains one of the most pressing issues in European conservation. Since the 1980s, the British breeding population of Garden Warbler Sylvia borin has declined by more th[...]

In altricial birds, the great effort involved in supplying food to nestlings can create trade-offs in the allocation of resources between the current brood and parental self-maintenance. In poor foraging conditions, parents have to adjust their [...]

There are serious concerns about the environmental and ecological degradation caused by modern agriculture and its impact on animal populations. There is therefore a need to assess the reproductive performance of free-living animals in agricultu[...]

In birds, energy supply during growth is a major predictor of the fledglings' physical condition and survival prospects. Differential quantity and quality of fledglings produced under varying nestling food supplies are likely to affect the numbe[...]

Estimates of annual survival rates of birds are valuable in a wide range of studies of population ecology and conservation. These include modelling studies to assess the impacts of climatic change or anthropogenic mortality for many species for [...]

Dawn and dusk choruses represent one of the most investigated topics in avian vocal behaviour, but their underlying basis remains unclear. As with the dawn chorus in passerines, dusk chorus in owls seems to support the mate and rival assessment [...]

Males in lek mating systems tend to exhibit high fidelity to breeding leks despite substantial evidence of skewed mating success among males. Although movements between leks are often reported to be rare, such movements provide a mechanism for a[...]

Natal dispersal has major consequences for the dynamics and genetic structure of populations. Female-biased natal dispersal, otherwise the norm in birds, is overridden when the place to move is limited, as on isolated islands. This effect was co[...]

Reliable estimates of survival and dispersal are crucial to understanding population dynamics, but for seabirds, in which some individuals spend years away from land, mortality and emigration are often confounded. Multistate mark-recapture metho[...]

Although variation in the dorsal plumage colour of male European Pied Flycatchers Ficedula hypoleuca has received a great deal of attention, females of the species have been usually considered to be nearly uniformly monochromatic brown. Using re[...]

Almost all animal social groups show some form of fission-fusion dynamics, whereby group membership is not spatio-temporally stable. These dynamics have major implications at both population and individual levels, exerting an important influence[...]

The geometrical properties of eggs - such as volume and surface area - have uses ranging from ecological, physiological and morphological studies in birds, to predictions of chick condition in the poultry industry. Although measurements of an eg[...]
