Tapaculo del Planalto

Identificación

The Planalto tapaculo is about 12 cm (4.7 in) long and weighs about 15 g (0.53 oz). The male's upperparts are mainly dark gray and the underparts paler gray. The flanks are buff with dark bars, which differentiate it from the similar but unbarred mouse-colored tapaculo. The female is browner and the juvenile has not been described.

Taxonomía

The Planalto tapaculos was previously included in the mouse-colored tapaculo (Scytalopus speluncae) but was described as a new species in 2005 based on differences in plumage and vocalizations. Its specific epithet honors Fernando Pacheco, a Brazilian ornithologist.

Comportamiento

The Planalto tapaculo forages for arthropods in the forest understory, primarily in thickets of terrestrial bromeliads and bamboo.<p>Almost nothing is known about the Planalto tapaculo's breeding phenology. A nest found in September in Argentina was not described but contained two eggs.<p>The Planalto tapaculo's song contains a long series of notes starting at a rate of two or three per second and accelerating into a trill [1]. This compares to five notes per second in the faster song of the mouse-colored tapaculo. The Planalto tapaculo has a distinctive, monosyllabic contact call and a loud alarm call.
