Fit for purpose? Analysis of the relationship between skull, beak shape and feeding ecology in Psittaciformes. [PDF]
J AnatPsittaciformes exhibit high levels of morphological diversity, particularly in skull and beak structure, previously linked to diet and body size. Although there were some levels of significance between diet and beak shape, body mass was a much stronger co‐variate. Diet is not determining beak shape within the clade.

Frequency dispersion reveals chromophore diversity and colour-tuning mechanism in parrot feathers [PDF]
Royal Society Open Science, 2018 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 ...
