Anodorhynchus

Anodorhynchus is a genus of three species of blue macaw each with yellow bare skin about the eye and mandible. One species ( A. hyacinthinus ) is the largest of all extant parrots. Of the two other species, one is extinct and one is endangered and restricted in range to arid zone canyons in eastern Brazil. The extinct Anodorhynchus glaucus was sister to A. leari , diverging 2 Mya (0.7–3.1), and they in turn are sister to A. hyacinthinus , diverging 3.7 Mya (1.4–5.6). This placement of A. leari could not be confirmed in the species tree because the sample was of low quality. For a review of morphological specialization and the ecology of Anodorhynchus , see Yamashita and Valle (1993). Sick and Teixeira (1983) note the obligatory cliff-nesting of A. leari .
