The cordillera tapaculo ( Scytalopus opacus ), syn. Scytalopus magellanicus opacus , belongs to the genus Scytalopus within the family of rump stilts (Rhinocryptidae) .
Originally the species was regarded as a subspecies (Ssp.) Of the Andentapaculo ( Scytalopus magellanicus ), then until recently as a subspecies of Páramotapaculo ( Scytalopus canus ) and referred to as ( Scytalopus canus opacus ). Due to different voices, the delimitation was made as an independent type in 2010.
The species occurs in the Andes in Ecuador , southern Colombia ( Central Cordillera ) and northern Peru .
The distribution area includes undergrowth of moist forests high up to the Páramo , preferably Escallonia myrtilloides and heather plants around and above the forest and tree line , sometimes also forest with Polylepis , in places also adjacent less high-lying moist forest with Chusquea bamboo, mostly between 2600 and 4000 m altitude .
The type epithet comes from the Latin opacus 'dark' .
features
The bird is 10–12 cm tall, the male weighs between 14 and 18, the female between 13 and 16 g. The species is named after dark pinnate with a little red-brown and is very similar to the Páramotapaculo ( Scytalopus canus ), but differs in its voice and ocher-yellow to cinnamon-brown coloring on the flanks and underside, sometimes also darker brown and a discreet, relatively narrow, dense, dark horizontal stripes. The female is somewhat paler than the male with a brown underside, dark bands on the tips of the tail feathers and on the tail, and more distinct brown flanks. Young birds can have very different plumage.
There is a sympathy with the Ecuador rust flank tapaculo ( Scytalopus spillmanni ) and the bamboo tapaculo ( Scytalopus parkeri ), both of which are limited to lower altitudes.
Geographic variation
The following subspecies are recognized:
- S. o. Opacus Zimmer, JT , 1941, nominated form - Central Colombia to Ecuador
- S. o. Androstictus Krabbe & Cadena , 2010 - Southeast Ecuador and Northern Peru
voice
The voice is described as a simple, fast trill for at least 30 seconds to a minute with about 34 tones per second.
Way of life
The food consists of arthropods , possibly also fruits , which are often sought in rib ferns on moss-covered tree trunks, along the branches in dense scrub and on the ground .
The breeding season is between March and May and November, otherwise little is known.
Hazardous situation
The stock is not considered to be at risk ( least concern ).
