The São Tomé grosbeak (Crithagra concolor) is the largest member of the Crithagra genus of canaries[2], 50% heavier than the next largest canary species [3], and possesses a massive bill for a member of that genus. It is endemic to the island of São Tomé.

For a long period this bird was known only from three nineteenth-century specimens. It was rediscovered in 1991. The current population is estimated at less than 50, and it is classified as critically endangered by the IUCN.[4] The main threat is habitat destruction.

The São Tomé grosbeak was formerly placed in the genus Neospiza (meaning "new finch"[2]) but was assigned to the genus Crithagra based on a phylogenetic analysis of mitochondrial and nuclear DNA sequences.[5][6]
