Chestnut Munia (Lonchura atricapilla) - HBW 15, p. 369

Taxonomy: Loxia atricapilla Vieillot, 1807, "les Grandes-Indes" = lower Bengal, India.
May form a superspecies with L. malacca and L. ferruginosa, and sometimes considered conspecific with former or with both, the three taxa being very similar vocally. Recent study of mitochondrial phylogeny indicated that present species (nominate race and sinensis) and L. ferruginosa were more closely related to each other than either was to L. malacca. Formerly, hybrid zone between present species and L. malacca apparently existed in E peninsular India (NW Orissa S to NE Tamil Nadu); it is suggested that some apparently intermediate individuals may be plumage morphs of L. malacca, as they also occur in Sri Lanka, well outside range of present species. In a mixed captive group, these two species associated and paired assortatively; also, no interbreeding reported in Hong Kong, where escaped individuals of both breed in Mai Po marshes. Has apparently hybridized with L. maja in Malay Peninsula; proposed species L. pallidiventer (known only in captivity) is believed to be a hybrid. Race brunneiceps sometimes subsumed in jagori. In Borneo, proposed races selimbauensis (described from Selimbau, in W Kalimantan) and obscura (from near Sampit, in S Kalimantan) both regarded as synonyms of jagori. Eight subspecies currently recognized.
