The spectral sensitivities of avian retinal photoreceptors are examined with respect to
microspectrophotometric measurements of single cells, spectrophotometric measurements …

The important role that mate choice plays in the lives of animals is matched by the large and
active research field dedicated to studying it. Researchers work on a wide range of species …

The interest in using Bayesian methods in ecology is increasing, however many ecologists
have difficulty with conducting the required analyses. McCarthy bridges that gap, using a …

Publisher Summary Birds can see ultraviolet (UV) light because, unlike humans, their lenses
and other ocular media transmit UV, and they possess a class of photoreceptor, which is …

We studied the effect of male coloration on interspecific female mate choice in two closely
related species of haplochromine cichlids from Lake Victoria. The species differ primarily in …

Assessment of color using human vision (or standards based thereon) is central to tests of
many evolutionary hypotheses. Yet fundamental differences in color vision between humans …

Good-genes hypotheses of sexual selection predict that offspring fathered by preferred
males should have increased viability resulting from superior genetic quality. Several …

To gain insights into the evolution and ecology of visually acute animals such as birds,
biologists often need to understand how these animals perceive colors. This poses a …

Social cues modulate the performance of communicative behaviors in a range of species,
including humans, and such changes can make the communication signal more salient. In …

The blue tit (Parus caeruleus) has been classified as sexually monochromatic. This
classification is based on human colour perception yet, unlike humans, most birds have four …
