Base de Datos de las Especies de Galápagos

Categoría de taxón: Aceptado

Syn.: Camarhynchus parvulus parvulus (Gould 1837); Camarhynchus parvulus salvini Ridgway 1894; Geospiza parvulus (Gould, 1837); Camarhynchus prosthemelas (Schlater & Salvin, 1870).

Origen: Endémica

Categoría en la Lista Roja de la UICN: Preocupación menor

Preferencias de habitat: Se encuentra en los bosques de la zona húmeda pero incluso hasta en la zona de transición.

Preferencias de alimentación: La mitad de su dieta artrópodos y larvas que busca en los árboles, en los musgos y a veces sobre el suelo, la otra mitad de su dieta consiste de frutos, semillas, hojas jóvenes, flores y néctar. La dieta es un poco diferente entre zonas secas e áridas, y entre temporadas (más frutos en temporada seca).

Papel trófico: Omnívoro

Modalidad de reproducción: Exclusivamente sexual

Biología reproductiva: El macho se exhibe en frente a un nido con forma de nido que construye solo. Cuando la hembra lo escoge como pareja, o usan este nido, o se 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.
