Appearance
The São Tomé grosbeak is the largest member of the canary genus Crithagra, 50% heavier than the next largest canary species.
Range and habitat
The São Tomé grosbeak, when rediscovered, was thought to inhabit exclusively lowland, old-growth forests in the lower elevations of the south of the island. Observations in the early 2000s indicated that the species was also inhabiting younger forests at higher elevations (between 1,300–1,400 m). Historically, old growth lowland forests were cleared to establish cocoa plantations that, when abandoned, grew into secondary forests, that are less suitable for the grosbeak.
It is endemic to the island of São Tomé.
Pins are Wikidata “endemic to” fields. Orange dots, when present, are GBIF occurrence tiles — survey bias included.

In crisis
The current population is estimated at less than 250, and it is classified as critically endangered by the IUCN.
