The Príncipe seedeater (Crithagra rufobrunnea) is a species of finch in the family Fringillidae. It is found only on the islands of São Tomé and Príncipe off the west coast of Africa.[2] Its natural habitats are subtropical or tropical dry forest and subtropical or tropical moist lowland forest.[1]

The Príncipe seedeater was formerly placed in the genus Serinus but phylogenetic analysis using mitochondrial and nuclear DNA sequences found that the genus was polyphyletic.[3] The genus was therefore split and a number of species including the Príncipe seedeater were moved to the resurrected genus Crithagra.[4][5]

Subspecies

Three subspecies are currently recognised:[6]

  • Crithagra rufobrunnea rufobrunnea, the nominate subspecies, endemic to Príncipe. Colour cinnamon-brown.[6]
  • Crithagra rufobrunnea thomensis, endemic to São Tomé. More greenish than the other subspecies, with a dull olive-brown colouration and a off-white patch on the throat.[6]
  • Crithagra rufobrunnea fradei, endemic to the Jockey's Bonnet islet off the southern coast of Príncipe. Larger than the nominate subspecies, with somewhat more reddish coloration and a darker bill.[6]
