Justification of Red List category
The species's population is estimated at less than 10,000 mature individuals. A total dependence on one or few species of bamboo, whose reproduction is followed by massive die-off events, suggests that the species's current population is fluctuating and declining due to the clearing of its bamboo habitat. It consequently qualifies as Vulnerable.

Population size: 2500-9999

Population trend: Decreasing

Extent of occurrence (breeding/resident): 605,000 km²

Country endemic: No
