Ocellated Tapaculo

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. == Description == This passerine averages 8.3-8.7 in (21–22 cm) in length and between 2.8 and 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 usually encountered in pairs or alone, hopping through bamboo along the forest floor. Preferring to stay close to the ground, it is more often heard than seen. It is possible to attract ocellated tapaculos with recorded or imitated calls, which they will approach to investigate from several kilometers away. == Ecology == === Distribution === It is sometimes divided into two subspecies: Acropternis orthonyx infuscatus is found in…
