IUCN Status

Facing an extremely high risk of extinction in the wild.

Critically Endangered - Facing an extremely high risk of extinction in the wild.


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species groups, such as vascular plants or vertebrates, updates proposed to the IUCN are shown, rather than the outdated, but currently-used status;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

General Ecology

Reproductive biology: Males display 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.
