The ocellated tapaculo (Acropternis orthonyx) is a large bird found in the northern Andes in South America. It is a highly distinctive tapaculo; traditionally united with its closest relatives in the Rhinocryptidae, this family is paraphyletic with the Formicariidae (ground-antbirds) but instead of merging the tapaculos with the ground-antbird family, recent sources tend to split the antpittas from the Formicariidae.
This passerine averages 8.3-8.7 in (21–22 cm) in length and between 2.8-3.5 oz (80 and 100 gram). The bird is mostly black with large white spots, a brown flank, and a reddish head and throat. A call, apparently given by birds to announce their presence to conspecifics, is described as "loud, emphatic WHEEUW! whistle" which as it seems can be heard from a long distance.
It is sometimes divided into two subspecies: Acropternis orthonyx infuscatus is found in the mountains of Ecuador and northern Peru. The nominate subspecies A. o. orthonyx ranges further north, from the Cordillera Central and Cordillera Oriental of Colombia to the mountains of northwestern Venezuela, with small populations also present in the Cordillera Occidental (in Antioquia and the Páramo de Frontino at least). It is not usually found on the Amazonian slope of the East Colombian and Venezuelan mountains it inhabits; on the Cordillera Oriental it is only known so far in a few places between 8,200-10,000 ft (2,500-3,000 m) ASL. The northern and southern populations are barely distinguishable and many authors accept no subspecies at all.
