The Lady Gouldian resides in the tropical parts of northern Australia. They are currently endangered in the wild due to loss of natural habitat as well as an infestation of air sac mites in the wild. Fortunately, they are well established in American Aviculture. Head colors can be red, black or orange.
Back colors can be green, blue or yellow.
Regardless of the mutation you choose, all are fairly easy to sex. The males have much brighter colors both on chest and belly. New mutations are being established at a surprising pace. The gouldian is a peaceful bird that does well in a mixed flight. When cage breeding, I use a 3 x 2 cage.
