About Pteroglossus frantzii Cabanis, 1861
The fiery-billed aracari (Pteroglossus frantzii Cabanis, 1861) is approximately 45 cm (18 in) long and weighs 225 to 280 g (7.9 to 9.9 oz). Like other toucans, it is brightly colored and has a large bill. An adult’s bill has a vertical ivory line at its base: the mandible is black, while the maxilla is mostly red, with a black culmen, yellow tip, and greenish base. Adults have black heads, necks, and throats, with a chestnut collar on the nape. Bare red skin surrounds the eye. Their back is blue-green and their rump is red. Their underparts are bright yellow, with a red band across the belly and a black spot in the center of the breast. Their thighs are chestnut. Females differ from males only by having a darker chestnut collar and a shorter bill. Immatures have duller overall plumage, and the plumage and bill patterns are indistinct. The fiery-billed aracari is found from the Gulf of Nicoya on Costa Rica's Pacific coast south into western Chiriquí Province, Panama; it formerly occurred as far east as Veraguas Province. It inhabits both the interior and edges of wet primary and secondary forest. In terms of elevation, it mostly ranges from sea level to 1,200 m (3,940 ft), but is occasionally found as high as 1,800 m (5,910 ft).
