Physical Description
The Lettered Aracari is a small toucan, measuring about 34–37 cm (13–15 inches) in length and weighing 130–160 grams.
Plumage and Features:
- Head and Back: Deep green, blending into the canopy.
- Breast and Belly: Bright yellow with a bold red band across the chest.

- Females are generally similar in coloration but may be slightly duller.
This bird is a visual masterpiece. Its combination of emerald green, vivid red, golden yellow, and the “written” look of its beak makes it unmistakable in the wild.
Habitat and Range
The Lettered Aracari is widely distributed across northern South America.
- Countries: Brazil, Colombia, Ecuador, Peru, Venezuela, and Bolivia.
- Preferred Habitat:
- Lowland rainforests
- Floodplain forests
- River-edge woodlands
- Occasionally found in secondary forests
- Altitude: Generally below 1,000 meters, though it can be seen at slightly higher elevations in some areas.
- Migration: Non-migratory; it stays in the Amazon and adjacent forests year-round.
This species is most active in the Amazon Basin, making it a familiar sight to those exploring South America’s vast rainforests.

Diet and Feeding Habits
Like other toucans, the Lettered Aracari is primarily a frugivore, though it also eats animal matter.
Diet Includes:
- Fruits (figs, berries, and rainforest fruits)
- Insects
- Small reptiles or frogs (occasionally)
- Bird eggs and nestlings (rarely, but it has been observed)
Feeding Behavior:
- Uses its large bill to pluck fruits from branches, often swallowing them whole.
- Plays a vital role as a seed disperser, helping maintain forest biodiversity.
- Joins mixed-species flocks, especially when fruiting trees attract other birds.
- This bird is a skilled climber, as it nimbly hops between branches while foraging for food.
The aracari’s diet makes it an ecological gardener, spreading seeds that grow into future trees.
Behavior and Lifestyle
The Lettered Aracari is a social bird, often seen in small groups of 2–6 individuals.
- Activity: Active during the day, spending mornings and late afternoons feeding.
- Flight: Quick and direct, though usually limited to short bursts between trees.
- Calls: High-pitched, squeaky, and repetitive calls. These vocalizations serve the purpose of keeping the flock in touch with one another.
- Roosting: Roosts in tree cavities, often squeezing together in tight spaces.
- Mating Behavior: Courtship may involve mutual feeding and bill-touching displays.
This aracari is curious but often shy around humans. Its calls, however, give away its presence in the dense canopy.
Reproduction and Lifespan
Breeding Season:
- Varies by region but often coincides with the rainy season when food is plentiful.
Nesting:
- Nests in tree cavities, often abandoned by woodpeckers.
- Both parents participate in nest excavation or cleaning.

Eggs:
- Typically 2–4 white eggs.
- Incubation period lasts about 16 days, shared by both parents.
Chick Care:
- Chicks are born blind and naked.
- Fed regurgitated fruit and insects by both parents.
- Fledge after about 6 weeks but may stay with parents for longer.
Lifespan:
- In the wild: Around 12–15 years.
- In captivity: Can live longer, sometimes up to 20 years.
Predators and Threats
Natural Predators:
- Raptors (hawks, eagles)
- Large snakes
- Arboreal mammals (monkeys, ocelots) that may raid nests
Environmental Threats:
- Deforestation: Amazon logging and land clearing reduce habitat.
- Fragmentation: Smaller forest patches mean fewer resources and nesting sites.
Human Impact:
- Occasionally captured for the pet trade due to its beauty.
- Vulnerable to habitat destruction caused by agriculture and mining.
Conservation Status
- According to the IUCN Red List, the Lettered Aracari is currently listed as Least Concern (LC).
- Population is considered stable, but localized declines occur in heavily deforested areas.
- Conservation depends largely on protecting large tracts of the Amazon rainforest.
Though not endangered, habitat protection is essential to keep populations healthy.
