[1] The IUCN Red List has assessed this bird as endangered with the population being estimated at 400 to 600 mature individuals remaining and still continuing to decrease.

Study the species's ecology, particularly home-range size and dispersal ability to help inform a global population estimate and assess the likely impact of habitat fragmentation.

Assess forest loss in the Philippines and gauge the species's likely rate of decline and degree of fragmentation of its populations.

This story was shown on GMA Network and is read in public events to increase awareness of this bird and to push back on poaching[8]
