Amenazas Se conoce que se encuentra afectado por la mosca parasite Philornis downsi, la cual causa alta mortalidad de pichones, y por viruela aviar. Las ratas introducidas probablemente son la segunda causa de mortalidad. Información adicional Venegas, L.

Ecología

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

Preferencias de habitat: Muy común, principalmente se encontraba en las zonas seca y transición, pero con la dispersión de gramíneas invasoras, se encuentra ahora anidando en todas los pisos climáticos.

Tipo de alimentación: Polifago

Flores, frutos, semillas y artropodos

Preferencias de alimentación: Se alimenta de flores (posiblemente un vector importante en la dispersión de polen), frutos, semilas, arthropodos, y fue observado buscando parásitos externos de iguanas y de tortugas las que extienden tanto el cuello como las patas para ese propósito.

Papel trófico: Omnívoro

Modalidad de reproducción: Exclusivamente sexual

Biología reproductiva: Los machos se exhiben en frente de un nido en forma de domo construido frecuentemente en cactus Opuntia. Hembras incuban solas 3-5 huevos, ambos alimentan los pichones.

Distribución

Mapa de distribución de las localidades de colección o registros de observación para esta especie en nuestra base de datos de colecciones.

Distribución: La especie se encuentra en todas las islas excepto Genovesa (posiblemente por competencia con el pinzón G. acutirostris), Darwin y Wolf (G. septentrionalis).
