. It was initially thought to be extinct for some time after 1952, but was rediscovered in 1986. Its rarity has been caused by the clearance of natural forest in southern Burma and peninsular Thailand. Its population was estimated at a mere nine pairs in 1997, then believed one of the rarest bird species on earth. A search for it in Burma in 2003 was successful and discovered that the species persisted at four sites with a maximum of 10-12 pairs at one location. This granted the species a reassessment from the
