Joazeiro, Baraúna, Imburana, etc.
Spix's macaw
In the wild, the most common seeds and nuts consumed by Spix's were from Pinhão ("Jatropha pohliana" var. "mollissima") and Favela ("Cnidoscolus phyllacanthus"). However these trees are colonizers, not native to the bird's habitat, so they could not have been historical staples of the diet.

Its diet also included seeds and nuts from Joazeiro ("Ziziphus Joazeiro"), Baraúna ("Schinopsis brasiliensis"), Imburana ("Commiphora leptophloeos" or "Bursera leptophloeos"), Facheiro ("Pilosocereus piauhyensis)", "Phoradendron" species, Caraibeira ("Tabebuia caraiba"), Angico ("Anadenanthera macrocarpa"), Umbu ("Spondias tuberosa") and Unha-de-gato ("Acacia paniculata").
