Plumage aberrations in Australian birds: A comment on Guay et al. (2012) and Frith & Murphy (2012)

Abstract

Colour aberrations in birds are still poorly known among ornithologists, and the terms used to describe such variations are often used inconsistently. Here, I provide further information on plumage aberrations described in Guay et al. (2012: Australian Field Ornithology 29, 23–30) and Frith & Murphy (2012: Australian Field Ornithology 29, 40–44), including a discussion of the ‘brown’ mutation.
