Ortygospiza atricollis | |
Ortygospiza is a genus of the estrildid finches. These birds are found in open grasslands in Africa. They are gregarious seed-eaters with short, thick, red bills. They are very terrestrial, with lark-like feet and claws.
Systematics
One to four species are usually recognized:
- Black-chinned quailfinch, Ortygospiza gabonensis
- African quailfinch, Ortygospiza fuscocrissa
- Black-faced quailfinch, Ortygospiza atricollis
The locust finch, Paludipasser locustella, is considered a member of this genus by some taxonomists.
Two issues are contentious: First, whether the locustfinch should be included here or given its own monotypic genus. Second, the "African quailfinch" complex might comprise one or three species. The two-species arrangement as found in most field guides and used by the IUCN, was recently shown to be based only on a single character (the color of the chin and throat). It is certainly erroneous, being contradicted by all other morphological, behavioral and DNA sequence data.
The molecular data would support a two-species arrangement with the taxa O. atricollis and O. fuscocrissa, but this is not supported by the other data. In conclusion, either O. gabonensis should be merged back into O. atricollis, or O. fuscocrissa should be restored to species status. Gene flow in the "African quailfinch" complex is still ongoing, and the three lineages therein either form a superspecies, or can be considered a single, wide-ranging and very variable species.[1]
