Base de Datos de las Especies de Galápagos

Categoría de taxón: Aceptado

This species is closely related to the Grey Warbler Finch, and were formerly considered conspecfic, but both species differ in appearance, distribution, habitat, and song. Syn.: Certhidea olivacea ridgwayi Rothschild & Hartert, 1899, Certhidea olivacea olivacea Gould, 1837, Certhidea olivacea mentalis Ridgway, 1894, Certhidea olivacea luteola Ridgway, 1894, Certhidea olivacea cinerascens Ridgway, 1890, Certhidea olivacea bifasciata Ridgway, 1894, Certhidea olivacea becki Rothschild, 1898.

Origen: Endémica

Categoría en la Lista Roja de la UICN: Vulnerable

Preferencia de zona de altitúd en Galápagos: Zona seca - zona húmeda

Preferencias de substrato o huésped: Forrajea en los árboles y arbustos buscando artrópodos, explora el follaje, busca en los musgos (sobre todo en temporada seca), busca en hojas terminales y epífitas.

Papel trófico: Carnívoro

Biología reproductiva: El macho se exhibe en frente de un nido cerrado que construyo solo. Cuando la hembra lo escoge como pareja , usan este nido, o juntos construyen uno nuevo. La hembra pone 2-3 huevos, incuba sola pero ambos alimentan los pichones. Cada pichón se queda con uno de los padres hasta 6 semanas.

Distribución: C. olivacea se encuentra en las islas centrales y occidentales más grandes. Está presente en las islas Pinzón, Fernandina, Isabela, Rábida, Santa Cruz y Santiago.
