Finches (Fringillidae)

Thick-billed Seedeater (Serinus burtoni) - HBW 15, p. 535

French: Serin de Burton German: Dickschnabelgirlitz Spanish: Serín de Burton
Other common names: Thick-billed Serin

Taxonomy: Strobilophaga burtoni G. R. Gray, 1862, Cameroon Mountains, 7000 feet [c. 2130 m].
Has previously been placed in genus Crithagra, and more recent mitochondrial DNA analysis indicates distant relationship with present African congeners, but detailed consideration of all taxa in current genus is required before full generic revision can be made. This species and S. melanochrous and S. rufobrunneus sometimes thought to form a superspecies; has been treated as conspecific with S. melanochrous, but differs morphologically and vocally. Four subspecies recognized.
