São Tomé grosbeak
|São Tomé grosbeak|
The São Tomé grosbeak (Crithagra concolor) is the largest member of the Crithagra genus of canaries 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. The main threat is habitat destruction.
The São Tomé grosbeak was formerly placed in the genus Neospiza (meaning "new finch") but was assigned to the genus Crithagra based on a phylogenetic analysis of mitochondrial and nuclear DNA sequences.
