Keel-billed Toucan

Features a predominantly jet-black plumage on its back, wings, and abdomen, which stands in stark contrast to a vibrant bright yellow bib covering the throat and chest, bordered below by a narrow red band. The undertail coverts are a brilliant crimson, while the uppertail coverts present a creamy white color. Its most remarkable physical attribute is its enormous yet lightweight bill, measuring between 4.7 and 5.9 inches (12 to 15 cm) in length, which accounts for nearly a third of its total body length of 16.5 to 21.6 inches (42 to 55 cm). The adult weight typically ranges from 13.4 to 17.6 ounces (380 to 500 g). This massive bill boasts a striking mosaic of colors, displaying a lime-green background, a light blue lower mandible, orange lateral patches, and a cherry-red tip. The zygodactyl feet are a beautiful shade of powder blue.

Geographical distribution: Occurs continuously along the Caribbean slope from southern Mexico (including Veracruz, Oaxaca, and Chiapas), across the Yucatan Peninsula, through Belice, Guatemala, Honduras, Nicaragua, Costa Rica, and Panama, extending into northwestern South America to include northern Colombia (Chocó region and inter-Andean valleys) and northwestern Venezuela.

Habitat: Primarily inhabits the canopy and mid-story of lowland tropical rainforests, premontane wet forests, gallery forests, and mature secondary growth. Although highly dependent on primary forest tracts, it displays moderate ecological plasticity, often visiting shade-grown coffee and cacao plantations, forest edges, and scattered pasture trees adjacent to continuous forest, from sea level up to elevations of 6,200 feet (1,900 m).

Feeding: Functions as an essential frugivore, serving as a key seed disperser for numerous native forest trees, particularly within the Lauraceae, Arecaceae, and Burseraceae families. Using its serrated bill, it plucks ripe fruits and tosses them backward into its throat. It supplements its frugivorous diet opportunistically with animal proteins, actively preying upon large insects, tree frogs, small lizards, as well as the eggs and nestlings of smaller avian species.

Behavior: Highly social, it is commonly observed foraging and traveling in small family groups or flocks of 6 to 12 individuals. Its flight is rather weak and undulating, characterized by rapid flaps followed by a glide, which makes it rely heavily on hopping through the canopy branches. It is a highly vocal species, producing a repetitive, low-pitched, frog-like croak often transliterated as "creek-creek". Social interactions include playful physical contact, such as "bill-fencing" and tossing fruits to one another.

Nesting: Breeding activity peaks between March and June. Lacking the physical adaptations to excavate its own cavities, it relies exclusively on natural tree hollows or old woodpecker nests located high in decaying tree trunks. The female clutches 2 to 4 glossless white eggs. Incubation is shared equally by both sexes and lasts between 16 and 20 days. The chicks hatch completely altricial—naked and blind—and remain in the cavity for 8 to 9 weeks, during which both parents continuously provision them with high-protein food and small fruits.

Conservation status: Classified as Near Threatened (NT) on the IUCN Red List. The wild population is experiencing a noticeable decline primarily due to habitat fragmentation and deforestation driven by agricultural expansion, alongside the persistent pressure of the illegal wildlife trade, where individuals are captured for the exotic pet market.
