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species groups, such as vascular plants or vertebrates, updates proposed to the IUCN are shown, rather than the outdated, but currently-used status;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.

Distribution

Galapagos island groups: Isabela, Marchena, Santa Cruz, Santa Fé.

Found on main islands except Fernandina and Pinzón (extinct ??).

Preference for altitude zone in Galapagos: Coastal zone-dry 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: Prefers dry shrub and woodlands with large Opuntia populations.

Trophic role: Omnivorous (feeding on both plants and animals).

Feeding type: Opuntia specialist, exploits flowers, nectar, pollen, seeds, and insects and larvae from rotting pads. Also feeds on other seeds.

Reproductive biology: Male displays in front of a dome shape nest built in an Opuntia cactus pad. Only females incubate (three to five eggs), both feed the chicks. May start breeding slightly earlier than other finches and particularly before the onset of the rain. Always build nests between pads of Opuntia.
