About the Black-mandibled Toucan
The yellow-throated toucan (Ramphastos ambiguus) is a Least Concern species of bird in the family Ramphastidae, the toucans, toucanets, and aracaris. It is found from Honduras south into northern South America and beyond to Peru.
Three subspecies of yellow-throated toucan are recognized: All three subspecies were originally described as separate species. R. a. abbreviatus was relatively early reassigned as a subspecies of R. a. ambiguus. Subspecies R. a. swainsonii differs from ambiguus by 1.35% in mitochondrial DNA which led to its treatment as a species by major taxonomies until about 2010.
The yellow-throated toucan is 47 to 61 cm (19 to 24 in) long and weighs 584 to 746 g (1.3 to 1.6 lb). The three subspecies differ little in their dimensions, though females' bills are shorter than males' in all three. Bill lengths vary between 15.1 and 19.8 cm (5.9 and 7.8 in) in males and 12.9 and 16.0 cm (5.1 and 6.3 in) in females. Other measurements differ little by sex. Their wing chord is 20.4 to 24.8 cm (8.0 to 9.8 in), their tail length is 14.0 to 16.2 cm (5.5 to 6.4 in), and their tarsus is 4.7 to 5.5 cm (1.9 to 2.2 in) long.
