The Cinnamon ibon (Hypocryptadius cinnamomeus), is a species of passerine 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 forestsand 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 mitochondrial and nuclear DNA as well as skeletal evidence, Jon Fjeldså and colleagues placed the species as the most basalmember of that family and a distinct subfamily.
