Population estimates have been somewhat divergent. The first estimate of world totals of the wild population was 5,000 birds in 1993, 2,500 to 10,000 birds in 2000, and less than 2,499 in 2002 in the first Red List of birds of Colombia. In 2004-2005 Jahn sent an unpublished estimate to Bird Life International (BLI) of 2,500 mature individuals, or some than 3,700 individuals including young, of which he believed 1,700 to 2,500 were to be found in the Panama-Colombia borderlands. BLI somehow derived an estimated total world population of 1,000 to 2,500 from that in 2005, and has maintained that number in subsequent assessments despite conflicting evidence.
