strating differences between males and females in the perception of sounds, and indicated how females might choose males on the basis of sound. Bird ong has also been a model system for understanding the interaction of neural and hormonal systems in the acquisition and control of learned sounds....

painted model of a male zebra finch whose beak and head movements during singing were deduced from high speed video recordings from singing males, thus realistically enough to function in experimental settings ranging from song acquisition studies to social behaviours to multimodal signal evolution. We...
Given that both sexes of most parrots learn new vocalizations throughout life and produce them in diverse social contexts, whereas few songbird species combine all these traits, why are parrots not a better model for the evolution of human speech than songbirds? We first note the technical const...
From the tracking data, we further calculated the spatial distances in all three dimensions between all pairwise combinations of birds throughout the four flight sessions (sample rate: 24 Hz). When normalized to the maximum distance detected for each bird pairing, each dimension and each flight...
Competitive exclusion may be avoided if one or both of the competing species evolves to use a different resource, occupy a different area of the habitat, or feed during a different time of day. The result of this kind of evolution is that two similar species use largely non-overlapping resou...
Family portraiture like this picks up an affectionate awareness of his son’s presence through boyhood into maturity; the evolution of their shared responsibilities; the love in the relationship, the familiar scent and sounds to each other, the ups and downs. In William’s features is a captiva...

consistent with optimization of sound propagation while both species produced longer calls in primary forests independently of geographic location (i.e. sympatry and allopatry). Our results suggest that both social and environmental pressures are important in shaping tamarin sounds. As their effects can...
