It has an estimated global extent of occurrence of 1,600,000 km2. It is found in Angola, Botswana, Lesotho, Namibia, South Africa and Zimbabwe. Males have vibrant red heads and chests while the females are duller. The resemblance to the cut-throat finch is unmistakable. The red-headed and cut-throat finch are the only members of the genus Amadina. Amadinas with their heavy beaks resemble members of the Lonchura, so they are actually more closely related to the Pytilias such as the Melba finch.[2] OriginOrigin and phylogeny has been obtained by Antonio Arnaiz-Villena et al..[3] Estrildinae may have originated in India and dispersed thereafter (towards Africa and Pacific Ocean habitats). HabitsOften seen in small flocks on dry savannahs, the red-headed finch is a ground feeder which feeds companionably with other species and often visits waterholes. It has a distinctive double-noted chuck-chuck call.[4] References1. ^{{IUCN|id=22719932 |title=Amadina erythrocephala |assessor=BirdLife International |assessor-link=BirdLife International |version=2013.2 |year=2012 |accessdate=26 November 2013}} 2. ^ 3. ^{{cite journal|last=Arnaiz-Villena|first=A|author2=Ruiz-del-Valle V |author3=Gomez-Prieto P |author4=Reguera R |author5=Parga-Lozano C |author6=Serrano-Vela I |title=Estrildinae Finches (Aves, Passeriformes) from Africa, South Asia and Australia: a Molecular Phylogeographic Study|journal=The Open Ornithology Journal|year=2009|volume=2|pages=29–36|url=http://chopo.pntic.mec.es/biolmol/publicaciones/Estrildinae_finches_2009.pdf | doi = 10.2174/1874453200902010029}} 4. ^Newman, K.
