El atlapetes del Chocó (Atlapetes crassus) es una especie de ave paseriforme de la familia Passerellidae propia de los Andes septentrionales. Anteriormente se consideraba una subespecie del Atlapetes tricolor.
Esta especie se encuentra en el occidente de los Andes. De las especies del género es una de las menos escondedizas y más arbóreas. Su nombre Atlapetes deriva del griego Atlas que en la mitología fue un titán quien fue convertido en una montaña, petes deriva también del griego y significa ave. Su epíteto tricolor deriva del latín y significa de tres colores.
Distribución y hábitat
Se encuentra únicamente en los Andes de Colombia y Ecuador. Su hábitat natural son los bosques húmedos tropicales de montaña.
Esta especie se encuentra en Colombia y Ecuador. En colombia se distribuye entre 800 y 2000 m de altura sobre el nivel del mar en la vertiente Pacífica desde las cabeceras del rio San Juan hasta el departamento de Nariño.
Reproducción
En el Alto Anchicayá en el departamento del Valle del Cauca se han observado individuos construyendo nidos en los meses de noviembre, febrero y mayo. También se registró un nido con un huevo de color blanco densamente manchado de pardusco en el mes de abril. Su nido tenía forma de copa y había sido construido cerca al suelo sobre un tronco podrido.
Tricolored brush finch
This brush-finch is no more tricolored than various other members of the genus, but it got the name. The three colors are the yellow of the underparts, the black of the face sides and the tawny crown stripe I gather, although the back is actually olive – so a fourth color! In general color and pattern the Tricolored resembles both the Pale-naped and Rufous-naped brush-finches; however the Tricolored has an entirely tawny, not rufous, crown stripe which does not turn whitish on the nape. Tricolored Brush-Finch is found in the Andes from Colombia to N Peru. It is typically a specie of forest edge, specifically in dense understory found in openings, overgrown pastures, and edges of clearings between 700 and 3000m in elevation.
It is widespread but not usually common, it is found usually in pairs and these do not tend to join the various mixed species foraging flocks that go through their territories. Little is known about its biology, and in particular how various sympatric brush-finches in this area of the Andes divide up habitats or minimize competition with each other.
