It inhabits tropic moist sub-montane and montane forest above 900 masl. IUCN has assessed this bird as a least-concern species. Despite a limited range, it is said to be locally common in its range. As it occurs in rugged and inaccessible mountains, this has allowed a large portion of its habitat to remain intact. However, there it is still affected by
