Thecinnamon ibon (Hypocryptadius cinnamomeus) is a species ofbirdendemic to the mountains ofMindanao in thePhilippines.[1]Monotypic within the genusHypocryptadius, it is classified as asparrow.[2] Its naturalhabitat is tropical moistmontane forests and mossy forests above 1,000 metres (3,300 ft).[1]
EBird describes the bird as "A fairly small to medium-sized bird . Bright cinnamon on the crown and back with darker wings and tail, a pale orange throat, chest, and sides, and white on the belly and under the base of the tail. Note the red eye and the silver-gray legs and bill. Often found in mixed-species flocks. No similar species in range. Voice is a mixture of high-pitched squeals, a sharp nasal 'wik', and a forceful, medium-pitched 'piii! piuu-piuu!' with the final notes downslurred."[3]
Monotypic within the genusHypocryptadius, it is classified as asparrow after being tentatively placed in the white-eyefamilyZosteropidae.[2] It has a skull and bill similar to that of the sparrows, and following a study of itsmitochondrial andnuclear DNA as well as skeletal evidence,Jon Fjeldså and colleagues placed the species as the mostbasal member of that family and a distinctsubfamily.[2]
Forages in the understory for insects and often joins mixed-species flocks that includeBlack-and-cinnamon fantail,Little pied flycatcher,Turquoise flycatcher,Negros leaf warbler and other small birds.
Nothing has been published about its breeding behaviour. Birds in breeding condition and enlarged gonads have been collected in February to May.[4]
Its habitat is in tropical moist montane and sub-montanemossy forests andforest edge above 1,000 meters above sea level.[5]
IUCN has assessed this bird as aleast-concern species . While it has a limited range, it is supposedly common in areas it is found. However, the population is said to be decreasing. This is due tohabitat loss due to legal andillegal logging,mining and conversion into farmlands throughSlash-and-burn or other methods.
