Ocellated Woodcreeper

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. Voice: The ocellated woodcreeper sings mostly at dawn and dusk, and usually gives only a few songs then. Its song varies geographically. For instance, in eastern Ecuador it is "a fast series of nasal notes...'whe-whe-whe-whe-whe-chéchécheow' ". In much of Brazil it is a "short, fast, descending, rattling series of notes" and in other parts "a rapid trill...'re-e-e-e-e-e-e-e-e-e-eet' ".
