Crimsonwing

The crimsonwings (Cryptospiza) are a genus of small passerine birds belonging to the estrildid finch family, Estrildidae. There are four species. They are found in parts of Sub-Saharan Africa, particularly the Albertine Rift; all four species occur there and two, Shelley's and dusky crimsonwings, are found nowhere else. They are secretive birds which mainly inhabit mountain forests with dense undergrowth. They usually forage on or near the ground, feeding mainly on seeds such as those of grasses and balsam.

Taxonomy

The genus Cryptospiza was introduced in 1884 by the Italian zoologist Tommaso Salvadori with Pytelia reichenovii Hartlaub, the red-faced crimsonwing, as the type species.^[1][2] The genus name combines the Ancient Greek κρυπτος/kruptos meaning "hidden" or "obscure" with σπιζα/spiza meaning "finch".^[3]
