The cinnamon ibon (Hypocryptadius cinnamomeus) is a species of bird endemic to the mountains of Mindanao in the Philippines.Monotypic within the genus Hypocryptadius, it is classified as a sparrow after being tentatively placed in the white-eye family Zosteropidae. Its natural habitat is tropical moist montane forests and mossy forests above 1,000 metres (3,300 ft). It has a skull and bill similar to that of the sparrows, and following a study of its and nuclear DNA as well as skeletal evidence, Jon Fjeldså and colleagues placed the species as the most basal member of that family and a distinct subfamily.
