Many migratory songbirds produce flight calls that vary, sometimes strikingly, among species in duration, frequency, modulation, and pattern, and little is known about what factors are responsible for this variation. Negative correlations betwee[...]

We analyzed sequences of two mitochondrial DNA (mtDNA) gene regions (control region and ND2) totaling 1477 base-pairs from 232 specimens of the white wagtail Motacilla alba obtained from 27 localities throughout Eurasia. Although overall haploty[...]

The trade-off between reproductive effort and adult survival in birds is modulated by several factors. Corticosterone and prolactin have additive effects on reproductive behaviour by stimulating foraging and parental behaviours, respectively. Wh[...]

Compilation and analysis of information from the literature regarding cross-species microsatellite amplification and polymorphism success, and relating this to source-target species genetic distance as estimated by pairwise cytochrome b (cytb) d[...]

While accelerated growth can be advantageous to nestling birds, there may be a tradeoff between rapid growth and resistance to food shortages. Common murres Uria aalge are colonial seabirds that benefit from reproductive synchrony. Individuals t[...]

Although it is well established that brown-headed cowbirds Molothrus ater are host generalists, the parasitism strategies of individual females are not well documented. Here we use microsatellite genotyping to characterize host use by individual[...]

Sexually selected displays, such as bird song, are expected to be costly. We examined a novel potential cost to bird song: whether a less favourable microclimate at exposed song posts would be predicted to raise metabolic rate. We measured the m[...]

The development and the continual expansion of urban areas have not only destroyed natural habitats, but also have drastically changed the environmental and ecological conditions of these areas. Consequently, species that have settled in these n[...]

Many birds have been shown to reduce their reproductive investment in response to infestation of nest sites by ectoparasites. Nest-dwelling parasite populations increase throughout the breeding season, and can reduce the condition and future sur[...]

Birds often exhibit greater reproductive tract development on the left side than right side. Behavioral evidence from the three species for which data has been published indicates that these species copulate more frequently on the left side of f[...]
