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

In craniates, opsin‐based photopigments expressed in the eye encode molecular 'light
sensors' that constitute the initial protein in photoreception and the activation of the …

One of the most striking outcomes of coevolution between species is egg mimicry by brood
parasitic birds, resulting from rejection behavior by discriminating host parents. Yet, how …

Birds are highly visual animals with complex visual systems. In this article, we discuss the
spectral characteristics and genetic mechanisms of the spectral tuning of avian visual …

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 …

The relative abundance and topographical distribution of retinal cone photoreceptors was
measured in 19 bird species to identify possible correlations between photoreceptor …

The visual sense of the Indian blue-shouldered peafowl Pavo cristatus was investigated with
respect to the spectral absorption characteristics of the retinal photoreceptors, the spectral …

Birds have four spectrally distinct types of single cones that they use for colour vision. It is
often desirable to be able to model the spectral sensitivities of the different cone types, which …

Although ultraviolet (UV) sensitivity is widespread among animals it is considered rare in
mammals, being restricted to the few species that have a visual pigment maximally sensitive …

This article suggests how we might understand the way potential predators see coloration
patterns used in aposematism and visual mimicry. We start by briefly reviewing work on …
