The endemic Tahiti reed-warbler Acrocephalus caffer occurs in two distinct morphs, a typical or yellow morph and a melanic or dark morph, which are found together in the valleys of the eastern and central parts of the island of Tahiti (Society I[...]

Among temperate-breeding birds, offspring survival and reproductive success are often inversely related to timing of breeding. The mechanisms that produce seasonal declines in offspring survival are not fully understood but may be related to tem[...]

Parent birds should take greater risks defending nests that have a higher probability of success. Given high rates of mammalian nest predation, therefore, parents should risk more for nests in areas with a lower risk of mammalian predation. We t[...]

Avian parental infanticide is apparently a rare phenomenon judging from the scant reports in the literature. However, unexplained cases of single nestling disappearance or of apparent fall from the nest are rather common and are routinely attrib[...]

Migrating birds make the longest non-stop endurance flights in the animal kingdom. Satellite technology is now providing direct evidence on the lengths and durations of these flights and associated staging episodes for individual birds. Using th[...]

While avian eggshell colouration has attracted biologists for decades, little is known about its variation within individuals. The main goal of this study was to explore within- and between-season repeatability of eggshell appearance in the grea[...]

McDonald and Griffith (2011) raise important points in their critique of reliance on feathers as a source of DNA for scientific research. Although those authors are right about many details, their one-size-fits all approach (i.e. prescribing blo[...]

Many bird species call during migration, but call rates not necessarily reflect migration intensity. They rather seem to increase under deteriorating flight conditions. Often, nocturnal mass collisions at illuminated structures coincide with suc[...]

In this study we test the potential of stable isotope analysis to reveal wintering origins of waders mixing at stopover sites, using the dunlin Calidris alpina as a case study. We determined stable carbon (d13C) and nitrogen (d15N) isotope signa[...]

The northern mockingbird Mimus polyglottos is a native species that is more abundant in urban than non-urban habitats (i.e. an urban-positive species). Abundance alone, however, is not an accurate index of habitat quality because urban habitats [...]

Natal dispersal is a fundamental component of the ecology and evolutionary history of birds, yet is often prohibitively difficult to study. We characterized natal dispersal for the first time in a bird using molecular genetic parentage analyses [...]

Specialist frugivores are the dominant consumers of mistletoe fruit in many regions and have been shown to intensify infections of host plants as a result of their rapid gut passage rates and dependence on existing infections. The role of specia[...]
