Moved the Sparrows in Literature section back here from House Sparrow, since it concerns sparrows generically, and this is where you would naturally think to find it.
Topic on Talk:Sparrow (usability testing)/Flow
The ITIS is using a rather old taxonomy (it isn't updated much, and I remember being strange in some areas), and I think the IUCN is the same; Zoonomen just displays the taxonomies of the "Peters Checklist, H&M 3rd ed., and CBBM" and the IOC is very fast to adopt proposed changes. The HBW (2009) places the genera in Ploceidae, and discusses the taxonomic issues. That doesn't make a "consensus" of sources, I think, so I'm not sure we should adopt this in taxoboxes. At any rate the article should discuss the genera in question in general, which is what I'll add if it's not clearer.
