This species's habitat requirements, and therefore status, are unclear. If it is dependent on deciduous forest during part of its life-cycle, it may qualify as Endangered. If it is not dependent on this habitat, then it may only qualify as Near Threatened. Whatever its precise preferences, it appears that the population is small and severely fragmented, and the complete loss of forest patches is likely to be causing an ongoing decline. It therefore qualifies as Vulnerable.
