Collared Aracari (S/F-T/G)

Juvenile collared aracari on Isla Nublar, Costa Rica

The collared aracari (Pteroglossus torquatus) is a species of bird in the family Rhamphastidae, the toucan family. It is found throughout Central and northern South America, and is also known as the banded, ringed, or spot-chested aracari. An omnivore that dwells in forests, this bird can be found from Mexico to Colombia and Venezuela. A population of collared aracaris was known from Isla Nublar, where the local Tun-Si tribe called them mokú-pá (meaning “owl parrot” in the Bribri language). In English, it is also called the spot-chested, ringed, or banded aracari.

There are three subspecies of collared aracari:

  • Pteroglossus torquatus torquatus, eastern and central Mexico to northwestern Colombia
  • Pteroglossus torquatus erythrozonus, southeastern Mexico through Belize and northern Guatemala
  • Pteroglossus torquatus nuchalis, northeastern Colombia and northern Venezuela

Based on locality, the subspecies found on Isla Nublar is most likely P. t. torquatus.


The collared aracari is of typical build for a toucan, with a distinctively large bill (this may make up a third of its overall body length). Its total body length as an adult is between 39 and 41 centimeters (15.5 to 16 inches), and it may weigh between 190 to 275 grams (6.7 to 9.7 ounces). As with all of its kind, it has zygodactyl feet; two toes face forward and two face back. Those seen on Isla Nublar demonstrate uncharacteristically anisodactyl feet, but this may be due to the unreliable narrative given in Jurassic Park: The Game‘s recounting of the latter half of the 1993 incident.

As with most toucans, the color of the collared aracari can be quite striking. The exposed skin on the head is black, turning red behind the eyes. Its irises are bright yellow. In addition to the black skin, the feathers of the head are black, as are those of the neck and body; on the rear side of the neck is a horizontal band of red which gives this animal its common name. The lower part of the bill is also black; the upper bill is yellow with tooth-like black markings, a black tip, and sometimes reddish markings toward the base. Its underbelly is yellow, turning olive toward its chest; there is a black spot in the middle of the breast, and the belly is marked by a horizontal red-edged black band. Its rear and upper tail are red, and the thighs are chestnut-colored while its legs are green.


Collared aracaris hatch without feathers and with a proportionately shorter beak. The chicks have pads on their feet to protect them from rough surfaces, as the nests lack lining.

As they grow, the feathers initially are duller in color; juveniles can be told apart from adults by their subdued red colors, sooty black parts, and paler belly. The band and spot on the underside are duller and more indistinct in juveniles.

This species fledges after about six weeks.

Sexual Dimorphism

Collared aracaris do not exhibit a significant amount of sexual dimorphism.

Preferred Habitat

The collared aracari is a forest-dwelling bird, living in lowlands and somewhat sparser woodland regions. It is found in warm, tropical environments.

Natural range

The collared aracari is found commonly throughout Latin America, breeding from Mexico to the northern parts of Colombia and Venezuela. It is also found on some offshore islands in this region, such as Isla Nublar, where it is locally known as mokú-pá. Much of the island consisted of lowland forests and woodland, which are ideal breeding and foraging habitats for the aracari. However, it was likely disturbed from its habitat by InGen activity on the island beginning in 1988.

On June 11, 1993, a single juvenile was sighted in the evening in the eastern forests of the island near the tertiary dilophosaur paddock. It had likely been startled by human activity, as it would not normally be active in the evening during inclement weather. The following morning, approaching midday, a juvenile was sighted at the maintenance building of the primary Triceratops paddock, where it was seen sharpening its bill on an oil can.

The effects of InGen activity on the collared aracari’s population between 1993 and 2015 are unknown; between 2002 and 2015, much of the central and southern island was redeveloped into a tourist attraction, which would have destroyed aracari habitat. In addition, the many de-extinct animals introduced to the island would have competed with it for food. If there were any collared aracaris remaining on Isla Nublar by June 23, 2018, they may have become extinct due to the eruption of Mount Sibo. This destroyed most of the northern island, including much of the last remaining heavily-forested parts of Isla Nublar at the time. With its food sources greatly diminished, the collared aracari may now be extinct on the island. It may persist on other islands in the Gulf of Fernandez, such as the Muertes Archipelago.


Collared aracaris are not found outside of their native range and are rare in captivity. They are sometimes kept as pets or in zoos, but so far there are no major populations established in other parts of the world.

Behavior and Ecology
Activity Patterns

This bird is generally diurnal. On Isla Nublar, juveniles have been known to be active between morning and midday, while one was seen active in the evening. This individual had been disturbed by human activity at the time and so may have been active at an unusual time.

Collared aracaris sleep with their tails folded over their backs.

Diet and Feeding Behavior

Collared aracaris are omnivores, though they mostly feed on fruit. The large beak is used to pluck fruits and other food from the trees it inhabits. It will also eat eggs, as well as small animals such as lizards and insects.

Social Behavior

This species is more social than some other toucans, with up to six animals roosting in one hollow together at night and throughout the year. Rearing the young is a communal activity and may involve individuals that are related to each other, such as older siblings. If so, the collared aracari might hold strong family bonds.

During the day, groups of collared aracaris can be seen flying through their habitat in groups of six to fifteen.

Collared aracaris make their nests in tree hollows or abandoned woodpecker nests. Their nests lack lining, and so may contain rough surfaces. The female will lay three white eggs in the nest, with both parents incubating them for about sixteen days. When the eggs hatch, the young are featherless and unable to fend for themselves; the parents, often accompanied by up to three other adults, will feed the chicks. The helpful adults may be offspring of the same to parents from a previous brood.

After approximately six weeks, the young become fledglings, and are able to leave the nest. The adults will continue to help them find food for the next several weeks, though.


The cry of the collared aracari is a loud and quick pseek or peeseek sound.

Ecological Interactions

For the most part, this animal is a frugivore. This means that it is important in spreading fruiting plants throughout its environment by means of seeds. Fruit found on Isla Nublar include native species such as the golden dewdrop (Duranta erecta) and banana (Musa callimusa) as well as introduced species such as the Moreton Bay fig (Ficus macrophylla) and West Indian lilac (Melia azedarach). All of these plants are known to attract birds with their fruits, and so could be spread on Isla Nublar by the collared aracari.

This bird also will eat small animals such as insects and lizards, helping to keep their populations under control. It may eat eggs from time to time, which would not only control bird populations, but also the introduced dinosaur species InGen brought to Isla Nublar beginning in 1988. However, most of the carnivorous dinosaurs were easily large enough to kill a collared aracari. As of the 1993 incident, collared aracaris were known to exist in or near territories inhabited by Dilophosaurus, Troodon, Triceratops, and Tyrannosaurus. Its natural predators likely included the common northern boa, which was the largest carnivore on the island prior to 1989.

They will make their nests in the abandoned homes of woodpeckers.

Cultural Significance

Like other toucans, the collared aracari is linked to confidence, showmanship, and vocal communication. Toucans are noisy and extravagant birds, easily recognized by their dramatically large bills, and so are iconic wildlife of Latin America and frequently shown in artwork from the region.

On Isla Nublar, the collared aracari was known to the indigenous Tun-Si tribe, who called the bird mokú-pá. Like the other animals, it would have taken part in building Mount Sibo in the Tun-Si’s mythic past. The Tun-Si indigenous name for this bird translates to “owl parrot” in the Bribri language, though why it was given this name is not known at the moment.

In Captivity

While toucans can be kept in captivity and are sometimes exotic pets, not much information is currently available specific to the collared aracari. It is a somewhat social, forest-dwelling, and mostly frugivorous bird; it eats eggs and small animals as sources of protein. If it is kept in captivity, these needs must be met. Since it is not a long-distance flier, it can probably do acceptably well in captivity but still would require a decently large enclosure in order to exercise.


While it has been researched by ornithologists, the collared aracari has not been used in any major scientific studies beyond gathering knowledge about its habits and biology.


This species is rated at Least Concern by the International Union for Conservation of Nature, meaning it is not threatened with extinction. The greatest danger to its survival is habitat loss.

On Isla Nublar, this species was protected by an agreement between Masrani Global Corporation and the Costa Rican Environmental Protection Society which lasted from 2005 until the closure of Jurassic World in December 2015. After this, its population may have become extinct due to the politics surrounding the de-extinct animals and plants living on the island; as governmental and corporate entities refused to protect the island ecosystem in order to let these artificial species become extinct, they inadvertently allowed naturally-occurring indigenous life forms to die out as well.


This bird is one of the charismatic fauna of Latin America, and so is partially responsible for the tourist industry in that part of the world. This was less the case on Isla Nublar, where tourism was primarily focused on the InGen facilities built on the island rather than the native wildlife.

It is generally not hunted. On rare occasions, toucan skulls are valued as macabre curiosities by tourists because of the bizarre proportions of the bill compared to the rest of the head. These are usually collected from already-dead birds found in the wild.


Like other toucan species, the collared aracari is not especially aggressive and unlikely to bite or peck a person. Give it space and do not harass it if you encounter one in the wild. The bill is unwieldy, making it inefficient for self-defense; if startled, the collared aracari is much more likely to flee from you. Keep fingers and other vulnerable parts away from its mouth should you end up handling one, and remain aware of its body language to gauge whether it is uncomfortable. As with all animals, err on the side of caution.
