The Cinderella waxbill (Glaucestrilda thomensis) is a near-threatened species of estrildid finch found in drier regions of southwestern Angola around the Namibe Province, north and east to the southwest of the HuÃÂla Province and north to Fazenda do Cuito in Huambo, and also in the extreme northwestern part of Namibia. It has an estimated global distribution of .
The Cinderella waxbill is found in subtropical and tropical (lowland), dry shrubland, savannah and forest habitats at altitudes of . It is observed that the recent development of a hydroelectric plant on the Cunene River at Epupa Falls has caused changes to insect biodiversity which were relied on by Cinderella waxbills during feeding of its young, thus threatening its food source to be depleted.
The Cinderella waxbill also eats grass seeds, nectar and insects; it is diurnal.
