Blue-eyed Ground-Dove

The next position on the list of the rarest birds in the world is Blue-eyed Ground-Dove. A species of bird belonging to the Columbidae family is the blue-eyed ground dove. It is unique to Brazil's Cerrado region.

The blue-eyed ground dove is 6.1 inches long, or 15.5 cm. Purplish red can be seen on the male's head, throat, wing coverts, upper tail coverts, and breast. Browner skin can be seen on the lower breast, tummy, flanks, shoulders, and back. It has white vent coverts and under tail coverts. Dark brown and chestnut with iridescent blue specks are visible on the closed wing. The outer tail feathers are darker and have a rufous center. It has blue eyes and naked gray skin all around. The adult female has paler underparts than the male. The juvenile's wing markings are unclear, and many of its feathers have rufous edges.

The Blue-eyed Ground-Dove, one of the rarest birds in Brazil, which is home to several unique species found nowhere else, has a population estimated at just 16 individuals. The name of this little dove refers to its striking blue eyes, which contrast with the rest of its rich tawny and rufous plumage and mirror the dots on its wings. Before 2015, when ornithologist Rafael Bessa made the discovery of a lifetime, the species was believed to be extinct.
