Population justification: The population size is estimated at 50,000-499,999 by Partners in Flight (2019), however previous estimates placed the number of mature individuals between 6,700-40,000 (O. Jahn in litt. 2009). It is here therefore tentatively assumed that the population size is ~50,000 mature individuals; however further confirmation of this estimate is required.
Trend justification: This species is suspected have undergone rapid declines during the past three generations (25 years) owing to hunting pressure and habitat loss and fragmentation, and these declines are predicted to continue. Forest decline throughout its range has been extensive during the past 25 years with over 12% of forest areas lost throughout the period (Tracewski et al. 2016). Subspecies griscomi is similarly declining throughout its range on Cozumel Island under continued increasing pressure (Caballero and Martínez-Morales 2006).
