Population justification: In 1992-1994, estimated densities in one area in Mexico indicated a wild population of 3,000-6,500 birds (E. C. Enkerlin-Hoeflich in litt. 1994). This estimate roughly equates to 2,000-4,300 mature individuals.

Trend justification: Historic densities recorded for the species were 25.2 birds/km2 in the 1970s (Castro 1976), falling to 5.7 birds/km2 in one area in 1992-1994 (E. C. Enkerlin-Hoeflich in litt. 1994, Enkerlin-Hoeflich 1995), indicating a decline of up to 77.4% over c.20 years. The decline is suspected to be continuing at a rate exceeding 50% over ten years, owing to the ongoing threats of trapping and forest clearance.
