São Tomé grosbeak : ウィキペディア英語版 | São Tomé grosbeak
The São Tomé grosbeak (''Crithagra concolor'') is a large, chunky finch with a massive bill. 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'' but was assigned to the genus ''Crithagra'' based on a phylogenetic analysis of mitochondrial and nuclear DNA sequences. ==References==
