Camarhynchus parvulus  (Gould, 1837)


English common name: Small Tree Finch

Spanish common name: Pinzón arboreo pequeño

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

Name status: Accepted name; taxon occurs in Galapagos.

Description: Smallest of the Darwin tree finches, 13 gr average, same as small ground finch. Short conical beak. Males develop a black hood with age, starting with face and head, while upper parts are olive green and underparts creamy. Males in San Cristóbal hardly ever have black plumage, but upper breast is heavily streaked. Females and young males have green-olive upper parts and creamy to yellowish underparts.

Known to be affected by the parasitic fly Philornis downsi that causes heavy chick mortality. Recent studies showed very low breeding success that may cause long term population collapse.

IUCN Status

Lowest risk category. Does not qualify for a more at risk category. Widespread and abundant taxa are included in this category.

Least Concern - Lowest risk category. Does not qualify for a more at risk category. Widespread and abundant taxa are included in this category.

The IUCN Red List assessments presented here may deviate from the global IUCN listings for the following reasons:

  • for well-known species groups, such as vascular plants or vertebrates, updates proposed to the IUCN are shown, rather than the outdated, but currently-used status;
  • for poorly-known species groups, such as lichenized fungi, a general assessment is not currently possible, therefore the list presented here is the regional IUCN Red List for the Galapagos Archipelago.


Galapagos island groups: Española, Fernandina, Floreana, Isabela, Pinta, Pinzón, San Cristóbal, Santa Cruz, Santa Fé, Santiago, Wolf.

Found on Isabela, Fernandina, Santa Cruz, Santiago, San Cristobal, Floreana, Baltra, Santa Fe, Pinzon y Rabida. Has been seen on Pinta but it is not known if there isa breeding population there. Found mostly in the highlands and the transitional zone.

Please be aware that this distribution map is automatically generated from database records (CDF and external specimens, literature records, and observations) and may not accurately reflect the currently-known distribution for all species.

General Ecology

Habitat preferences: Found in forests both in the humid and more arid transition zones.

Trophic role: Carnivorous (feeding on animals).

Feeding type: Approx. 50% of diet comprises insects and larvae foraged mainly from trees and moss above ground level although they do occasionally forage on the ground. The other half of their diet comprises fruits, seeds, young leaves, flowers and nectar. There is variation in the diet between the humid and arid zones, and between seasons (more fruit is eaten in the dry season).

Reproductive biology: Male displays in front of a dome shape nest high up in the canopy. Once chosen, the pair either use this nest or build a new one. Only females incubate (two to three eggs), both feed the chicks. Fledglings stay for up to 6 weeks with a parent, either with the male while the female starts a new clutch, or, one with the female and the other with the male.
