Medium‑sized toucan (total length 42–55 cm, of which ~30 % is bill) with velvety black plumage, lemon‑yellow throat and chest bordered by a fine red line. Uppertail coverts brilliant crimson; rump and uppertail coverts sky‑blue. The oversized bill (12–15 cm) shows a kaleidoscope of lime‑green, orange, cerulean and crimson, yet weighs little because of its pneumatised bony lattice. Legs and feet are powder‑blue; iris dark maroon. Sexes appear identical; juveniles have shorter, duller bills and browner plumage.
Sexual dimorphism refers to the physical differences between males and females of the same species that go beyond reproductive organs. For example, size, colour or form.

Canopy and sub‑canopy of lowland evergreen rain forest, seasonally moist gallery forest and tall secondary forest from sea level to ~1 500 m, chiefly on Caribbean and south‑Pacific slopes; frequents fruiting trees in agro‑mosaics with > 30 % canopy cover.
Frugivore (> 80 % diet) consuming Virola, Ficus, Cecropia fruits; supplements with insects, lizards and nestling birds; major long‑distance seed disperser.
Social Structure & Behaviour
Activity pattern: diurnal; peak foraging 06:00–10:00 & 15:00–17:00.
Group size: forage in small parties of 3–12; communal roosts up to 30 in tree cavities or bamboo clumps.
Breeding system: seasonally monogamous; both sexes excavate / enlarge old woodpecker holes 10–25 m high.
Territoriality: loose; pairs defend ~1 ha around nest with bill clacks and croaking calls.
Communication: yelping “rrraak‑rrraak” series, snoring croaks; bill tapping; mutual preening.
Special behaviours: juveniles play by passing fruit or sticks bill‑to‑bill; thermal bill flushing visible with infrared cameras.

Taxonomic classification is a hierarchical system used in biology to organize and name living organisms. It arranges species into nested groups based on shared characteristics and evolutionary relationships.
🌍 The IUCN status refers to the conservation category assigned to a species by the International Union for Conservation of Nature, based on its risk of extinction
Can toss fruit up, catch and swallow whole items > 20 mm wide.
Bill surface area can dissipate up to 60 % of metabolic heat during midday rest.
Plays “bill fencing” and tosses sticks during social interactions in communal roosts.
