Population justification: The species is described as fairly common. Based on transect data, the population has been estimated to number roughly 14,000-25,000 individuals (Angehr and Blewett 2010), equating to 9,000-17,000 mature individuals.
Trend justification: Following the regeneration of formerly cleared areas on Coíba Island, the population is thought to be increasing slowly (G. Angehr in litt. 2020).
