FAQ: what is the difference between psittacofulvins and psittacine?
There is no difference. Psittacofulvins AKA psittacine or parrodienes [1], [2, p. 242], [3, P. 380] is the class of pigments (red, orange, yellow) that is limited to Psittaciformes (parrots). In Europe in aviculture they prefer to use the more popular name psittacine (it started with the budgies). In scientific publications it is advised to use the term psittacofulvins.
