It referred to the colour of undyed buffalo leather, such as soldiers wore as some protection: an eyewitness to the death in the Battle of Edgehill (1642) of Sir Edmund Verney noted "he
Budgerigar colour genetics Budgerigar colour genetics The science of budgerigar colour genetics deals with the heredity of mutations which cause colour variation in the feathers of the species known scientifically as "Melopsittacus undulatus". Birds of this species are commonly known by the terms 'budgerigar', or informally just 'budgie'. The wildtype (natural-coloured or wild occurring) budgerigar's colour is called Lightgreen. The feathers of most parrot species, including budgerigars, contain both a black type of "melanin" named "eumelanin" along with a basic yellow pigment named psittacofulvin (psittacin for short). Some other parrot species produces a third pigment named advanced-psittacin which enables colour & tones ranging
