Finches (Fringillidae)

Black-capped Siskin (Carduelis atriceps) - HBW 15, p. 549

French: Tarin sombre German: Guatemalazeisig Spanish: Jilguero Capirotado

Taxonomy: Chrysomitris atriceps Salvin, 1863, near Quetzaltenango, 8000 feet [c. 2440 m], Guatemala.
This species and C. pinus and C. spinus have been thought to form a superspecies. Possibly only distantly related to the South American group of siskins, and has recently been suggested that the three be separated in genus Spinus, but comprehensive review required of all species currently included within present genus in order to determine true relationships. Hybridizes with C. pinus of S race perplexa, progeny showing intermediate characters; may be conspecific, but extent of reproductive isolation between these two taxa requires further research. Monotypic.. View all taxonomy...
