Ocellated Woodcreeper

Identificazione

The ocellated woodcreeper is 20 to 24.5 cm (7.9 to 9.6 in) long and weighs 24 to 42 g (0.85 to 1.5 oz). It is a slim, medium-sized woodcreeper with a long and nearly straight bill. The sexes are alike. Adults of the nominate subspecies X. o. ocellatus have a dark brown crown and nape with fine buff streaks on the crown. Their back is plain reddish brown to olive-brown, their rump and wings cinnamon-rufous, and their tail a darker cinnamon-rufous. Their throat is deep buff with darker edges to the feathers. Their underparts are olive-brown that becomes more rufescent on the undertail coverts. Their upper breast has large buff "teardrops" with weak darker borders, their lower breast has weak buff streaks, and their belly is unmarked. Their iris is dark brown, their bill blackish with a pale gray mandible, and their legs and feet gray. Juveniles are similar to adults but with heavier markings on their underparts.<p>The other subspecies of the ocellated woodcreeper differ from the nominate and each other thus:

Tassonomia

The ocellated woodcreeper's taxonomy is unsettled. The South American Classification Committee of the American Ornithological Society (SACC) and the Clements taxonomy have long treated it as a species with seven subspecies. The International Ornithological Committee (IOC) formerly treated it as a species with four subspecies; the other three were treated as Tschudi's woodcreeper (X. chunchotambo). In July 2023 the IOC lumped Tschudi's into the ocellated woodcreeper, resulting in the same treatment as that of the SACC and Clements.<p>The seven subspecies recognized by these taxonomic systems are:<p>However, BirdLife International's Handbook of the Birds of the World (HBW) considers only X. o. perplexus and X. o. ocellatus as the ocellated woodcreeper. It retains X. o. napensis, X. o. chunchotambo, and X. o. brevirostris as Tschudi's woodcreepr and treatsX. o. lineatocapilla and X. o. beauperthuysii as the line-crowned woodcreeper.<p>This article follows the single species, seven-subspecies, model.

Areale e habitat

The subspecies of the ocellated woodcreeper are found thus:<p>The ocellated woodcreeper primarily inhabits evergreen forest. Most of the subspecies favor terra firme forest and are also found in várzea, other seasonally flooded forest types, and wooded swamps. The three "Tschudi's" subspecies are found in terra firme but are more common in montane forest and cloudforest. All prefer the interior of mature forest but also occur at its edges and in secondary forest. The species mostly occurs at elevations below 500 m (1,600 ft) but reaches 1,800 m (5,900 ft) in the Andes.
