Abstract
The Cuban Macaw Ara tricolor was a species of macaw native to Cuba and Isla de la Juventud in the Caribbean that became extinct in the 1860s. Morphologically it was similar to, but distinctively smaller than the large red macaws – Scarlet Macaw A. macao and Red-and-green Macaw A. chloropterus. A close affinity with the Scarlet Macaw has been suggested based on plumage similarities. In this study we use complete mitochondrial genome sequences to examine the phylogenetic position of the Cuban Macaw. Our results do not indicate a sister-species relationship with the Scarlet Macaw, but place the Cuban Macaw sister to the two red species and the two large green macaws, the Military Macaw A. militaris and the Great Green Macaw A. ambiguus. Divergence estimates suggests that the Cuban Macaw separated from this group approximately 4 million years ago.

  2. These sister groups of "red" and "green" has a conservative pattern of turquoise wings and bicolored tail (maroon and bluish). Morphologically its is very conservative characters.
