Somehow the Orange-bellied Parrot is always getting into trouble. Image by Debbie LustigIf you had to ask an average Australian the name of a threatened bird in this country, many would nominate the Orange-bellied Parrot. Critically endangered, and with fewer than 50 left in the wild, it is justifiably one of Australia’s most well-known endangered species.
Birds around the world rely on colourful plumage to identify and assess their kinsmen. Birds see colour using four colour visual pigments in their cone cells in addition to a rod pigment that is used in dim light vision. Each of these visual pigments is made up of one of five opsin proteins (LWS, SW1, SWS2, RH2 and RH1) and a chromophore, where each pigment absorbs a different range of light wavelengths. In some non-avian species the spectral sensitivities of these visual pigments have co-evolved with body colour and differ between individuals of the same species. Curiously, however, to date all studies suggest that the visual pigments vary little within the avian class, and even less within a particular species. To investigate further, Ben Knott, a researcher at Deakin University, and Wayne Davies, from the University of Western Australia, both in Australia, and their colleagues turned to the unusual parrot Platycercus elegans whose plumage can range from red to yellow (p. 4454).
