Base de Datos de las Especies de Galápagos

Categoría de taxón: Aceptado

Syn.: Geospiza scandens abingdoni (P. L. Sclater & Salvin, 1870); Geospiza scandens intermedia Ridgway, 1894; Geospiza scandens rothschildi Heller & Snodgrass, 1901; Geospiza scandens scandens (Gould, 1837); Cactornis scandens Gould, 1837; Cactornis assimilis Gould, 1837; Cactornis abingdoni (Sclater & Salvin, 1870).

Origen del taxón: Endémica

Categoría en la Lista Roja de la UICN: Preocupación menor

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

Preferencias de habitat: Prefiere formaciones secas de árboles o arbustos que mantengan buenas poblaciones de cactus Opuntia.

Preferencias de alimentación: Especie especializada en alimentarse de Opuntias, de la cual come sus flores, néctar, polen, semillas, además de insectos y larvas que recoge de cladodios en descomposición. Se alimenta también de algunas otras semillas.

Papel trófico: Omnívoro

Modalidad de reproducción: Exclusivamente sexual

Biología reproductiva: El macho se exhibe en frente de un nido con forma de domo, construido entre cladodios de Opuntia. Solo las hembras incuban de 3 a 5 huevos pero ambos alimentan los pichones. La reproducción empieza antes de los otros pinzones, peculiarmente antes de empezar la época lluviosa.
