O'Neill's Antpitta
The Panao antpitta (''Grallaria oneilli'') is a species of bird in the family Grallariidae. It is endemic to Peru. It is a member of the rufous antpitta species complex and was formally described in 2020 by R. Terry Chesser and Morton L. Isler. Taxonomy The Panao antpitta was described as a species on the basis of differences in plumage, vocalizations and genetics. It forms a sister group with the Chachapoyas antpitta and the Junín antpitta. The birds in the Panao antpitta's range were formerly believed to be part of subspecies ''G. rufula obscura'' (now elevated to the Junín antpitta, ''G. obscura''). The Panao antpitta's specific name, ''oneilli'', are named for Dr. John P. O'Neill, the ornithologist who collected the type specimen in Huánaco in 1983. Distribution and habitat The Panao antpitta is endemic to the eastern slope of the Peruvian Andes in the departments of Huánaco and Pasco. They inhabit humid montane forests and are usually found in the understory ...

Bird
Birds are a group of warm-blooded vertebrates constituting the class Aves (), characterised by feathers, toothless beaked jaws, the laying of hard-shelled eggs, a high metabolic rate, a four-chambered heart, and a strong yet lightweight skeleton. Birds live worldwide and range in size from the bee hummingbird to the ostrich. There are about ten thousand living species, more than half of which are passerine, or "perching" birds. Birds have whose development varies according to species; the only known groups without wings are the extinct moa and elephant birds. Wings, which are modified forelimbs, gave birds the ability to fly, although further evolution has led to the loss of flight in some birds, including ratites, penguins, and diverse endemic island species. The digestive and respiratory systems of birds are also uniquely adapted for flight. Some bird species of aquatic environments, particularly seabirds and some waterbirds, have further evolved for swimming. B ...
