Collared aracari preferred habitat is generally woody lowland forest or humid rainforest with secondary growth. These birds are found from sea level up to 1500 meters. They are fairly common throughout their range. (Sibley and Monroe, 1990; Skutch, 1985a; Stiles and Skutch, 1989)
Collared aracaris have a mostly black back with a green tinge to the feathers. The plumage of the neck and throat is blackish while the upper tail and rump are bright red. The undertail and belly plumage is mostly yellow with black and red stripes across the abdomen. The upper portion of the beak is whitish-gray or sometimes whitish. The lower beak and lower ridge of the upper beak are black. The lower edge of the upper beak has widely-spaced tooth-like protrusions. The beak is light weight because of a crisscross of rods made out of bone. The skin that surrounds the beak and eyes is bright red. The eyes are yellow. In this species the female is similar to the male except that her beak is smaller. Juvenile collared aracaris have a duller appearance than adults. Average weight is about 230 g and body length is 41 cm on average. ("Animals: Collared Aracari", 2001; Skutch, 1985a; Skutch, 1985b)
Collared aracaris are monogamous and may mate for life. Courtship behaviors are not well known. Collared aracaris are cooperative breeders. Offspring from the previous clutch or clutches will help parents take care of their siblings. Approximately five to six adults will attend nestlings at a time, bringing food and guarding them. It is not known whether cooperative breeding is common in other toucan species. (Skutch, 1985b; Stiles and Skutch, 1989)
Collared aracaris breed once a year from January to May. They lay three eggs in a cluth. (Stiles and Skutch, 1989)
Collared aracaris roost and make nests in large woodpecker holes or natural cavities about 6 to 30 m (20 to 100 ft) off the ground. These birds do not use materials for nesting. During the incubation period only one bird stays in the nest, usually one of the mating pair, to keep the eggs warm. Both of the parents take turns incubating the egg from 15 up to 18 days, with an average of 16 days. It takes another six weeks for the young to be able to leave the nest, at fledgling. The exact age at which collared aracaris are reproductively mature is unknown. However, related toco toucans become sexually mature between the ages of 3 and 4 years old. ("Toco Toucan", 2002; Skutch, 1985b; Stiles and Skutch, 1989)
Collared aracaris live in groups and five adults may roost in the nest cavity after the eggs hatch. Up to six adult birds will bring food to the nestlings. Some of the other adult birds that attend the nest are siblings to the new hatchlings, probably from the previous brood.
Collared aracaris, like other toucans, are born blind and naked and with very short beaks. On their heels they have special pads that protect them from the bottom of their nest. After six weeks they are ready to leave the nest but continue to be fed by adults for a few more weeks. ("Animals: Collared Aracari", 2001; Skutch, 1985a; Stiles and Skutch, 1989)
Collared aracaris live in small flocks of 6 to 15 birds, some of which are related. Throughout the year collared aracaris sleep together with their tails folded over their backs; up to six adults and fledglings will sleep in this way in woodpecker holes. The flock may have several woodpecker holes and natural cavities that they use to roost in.
Pteroglossus torquatus fly using rapid beats of their wings. They use short glides to get to a perch and springy “jay-like” jumps to move along a branch. ("Animals: Collared Aracari", 2001; Skutch, 1985b; Stiles and Skutch, 1989)
It does not appear that P. torquatus is territorial.
Collared aracaris use different vocalizations for various purposes. The general call is a loud peeseek, pink, or a harsh pseek. They emit a grahhrr sound when aggravated. The alarm call is a shrill eeeyeeek. When collared aracaris are excited they emit a pitit sound. (Stiles and Skutch, 1989)
In captivity collared aracaris are fed a diet that consists of dog food and fresh fruit. They are given plenty of water to bathe in and drink. They are also given a weak tea to drink every other month so that it will bind to the iron in their diet and help expel the iron. Iron damages their liver and is deadly. It is believed that the tannins in the tea resemble those found in water that these birds would drink in the rainforest. (Foley, 2006)
As with all toucans, the bill of collared aracaris is specially designed to be durable for eating fruit, but also lightweight for flight. Though it looks heavy, the beak is thin. The inside is reinforced with a crisscross of lightweight rods made of bone. The “tooth-like” protrusions help toucans catch and grasp food in the bill. (Skutch, 1985b)
Collared aracaris are agents of seed dispersal in the tropical forests where they live. Seeds pass through their digestive tract unharmed and are deposited away from the parent plant.
Aside from their important ecosystem roles, the main positive benefit to humans of P. torquatus is ecotourism. These birds are common throughout their range. Bird watchers see a great number of these birds when they go on hikes. (Sibley and Monroe, 1990)
Collared aracaris are also traded in the pet industry. If raised from chicks and hand fed, they become quite tame. (Foley, 2006)
There are no known adverse effects of Pteroglossus torquatus on humans.
Collared aracaris, as of 2004, were classified as Least Concern (LC) by the IUCN red list of threatened species, they have no special status according to CITES.
Among native peoples, toucans are linked to evil spirits and are thought to be manifestation of demons. Medicine men will also use toucans as a way to fly to the world of the spirits. ("Toco Toucan", 2002)
