Base de Datos de las Especies de Galápagos

Categoría de taxón: Aceptado

Origen del taxón: Endémica

Categoría en la Lista Roja de la UICN: Preocupación menor

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.

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.
