Bulgunnia has been classified by BirdLife International as an Important Bird Area because it is a stronghold for the restricted-range and near-threatened Chestnut-breasted Whiteface as well as supporting the biome-restricted Inland Dotterel, Bourke's Parrot, Chiming Wedgebill, Cinnamon Quail-thrush, Pied Honeyeater and Thick-billed Grasswren.
