Variation in animal coloration is often viewed as the result of chemically distinct pigments conferring different hues. The role of molecular environment on hue tends to be overlooked as analyses are mostly performed on free pigments extracted from the integument. Here we analysed psittacofulvin pigments within parrot feathers to explore whether the in situ organization of pigments may have an effect on hue. Resonance Raman spectra from a red region of a yellow-naped amazon Amazona auropalliata ...

Vivid plumage colors are some of the best examples of elaborate trait evolution resulting from sexual selection. Bird feathers often contain high concentrations of pigment or intricate microstructures for reflecting light at distal feather tips, in order to maximize color presentation to intended viewers (e.g., prospective mates, rivals). However, here we describe a rare form of “hidden” plumage coloration, whereby several species of heron (Pelecaniformes: Ardeidae) have powder down tracts liber...

Abstract The Waitematā Harbour is a drowned river valley in the south-west of the Hauraki Gulf, on the north east of New Zealand’s North Island. The central business district for the city of Auckland is situated on the southern shore of the central Waitematā Harbour and is New Zealand’s largest and fastest growing city. The Waitematā Harbour hosts a major international port, New Zealand’s primary naval base and international cruise terminal, as well as a large and committed community of recreati...

ABSTRACTThe Glen Murray fossil penguin was one of the first ancient penguins to be reported from the North Island of New Zealand when it was described in 1973. However, its significance for penguin diversity has remained largely unresolved since initial description. Here we show that the Glen Murray penguin exhibits two of three traits that are autapomorphic for Kairuku: the femur is very stout with a midshaft width <15% of the total femoral length and the tibiotarsus has a distinctly convex med...

Detailed anatomical models can be produced with consumer-level 3D scanning and printing systems. 3D replication techniques are significant advances for anatomical education as they allow practitioners to more easily introduce diverse or numerous specimens into classrooms. Here we present a methodology for producing anatomical models in-house, with the chondrocranium cartilage from a spiny dogfish (Squalus acanthias) and the skeleton of a cane toad (Rhinella marina) as case studies. 3D digital re...

ABSTRACT A small group of pigment classes is responsible for the wide range of plumage colors in modern birds. Yellow, pink, and other “warm” feather colors of many species are attributed to carotenoid pigments, a plumage trait that has an uneven distribution across modern bird species. Carotenoid plumage pigments are especially rare among fowl (superorder Galloanseres), and until recently, the Pink-eared Duck (Malacorhynchus membranaceus) from Australia provided the only evidence that any speci...

Elaborate plumages and songs in male birds provide classic evidence for Darwinian sexual selection. However, trait elaboration in birds is not gender-restricted: female song has recently been revealed as a taxonomically-widespread trait within the songbirds (oscine Passerines), prompting increased research into likely functions and social/ecological correlates. Here we use phylogenetically-informed comparative analysis to test for an evolutionary association between female song and plumage color...
