Toco Toucan

About

The Toco Toucan, also known as the Common Toucan or Giant Toucan, is the largest and arguably the best-known species in the toucan family. It is easily recognizable by its striking black plumage, white throat, and enormous, brightly colored orange-yellow bill with a black spot. Despite its size, the bill is surprisingly lightweight due to its hollow, bony structure.

Size & lifespan

Length

55-65 cm (21.5-25.5 in)

Wingspan

109-152 cm (43-60 in)

Weight

500-860 g (1.1-1.9 lbs)

Lifespan

Up to 20 years in the wild, 20-26 years in captivity

Diet

Omnivore, primarily frugivorous (fruit-eating), but also consumes insects, eggs, nestlings, and small reptiles.

Physical characteristics

Plumage

Predominantly glossy black body plumage. A striking white throat and upper breast, bordered by a narrow red band. The undertail coverts are red, and the uppertail coverts are white.

Beak shape

Enormous, prominent, and slightly curved bill, typically orange-yellow with a large black oval spot near the tip of the upper mandible. The culmen (upper ridge) is often reddish-orange at the base. The bill is serrated along the edges.

Eye color

Dark brown, surrounded by a patch of bare, bright blue skin, which is further encircled by a ring of bare orange skin.

Leg color

Bluish-gray

Distinguishing features

The combination of its large size, black body, white throat, and especially its massive, brightly colored orange-yellow bill with a black spot, makes it unmistakable. The blue and orange bare skin around the eye is also a key feature.

Juvenile appearance

Juveniles resemble adults but have a duller plumage, a smaller and less brightly colored bill, and the black spot on the bill may be less defined or absent. The bare skin around the eye is also less vibrant.

Seasonal changes

No significant seasonal changes in plumage or bill coloration.

Sexual dimorphism

Males and females are generally similar in plumage and bill coloration, though males tend to be slightly larger and have a proportionally larger bill than females. This difference is often subtle and not reliable for field identification.

How to identify

1. 1

   Size and Shape

   Look for a large, stocky black bird with a disproportionately large bill. Its overall silhouette is distinctive.

2. 2

   Bill Coloration

   The most striking feature is the massive orange-yellow bill with a prominent black oval spot near the tip of the upper mandible. No other toucan has this exact bill pattern.

3. 3

   Plumage Pattern

   Note the glossy black body, contrasting white throat and upper breast, and the narrow red band separating the white throat from the black belly. White uppertail coverts and red undertail coverts are also key.

4. 4

   Eye and Facial Skin

   Observe the dark eye surrounded by bare blue skin, which is then encircled by a bare orange ring. This combination is unique.

5. 5

   Vocalization

   Listen for its distinctive deep, frog-like croaking calls, often repeated. This sound is very characteristic of the species.

Habitat & range

Biomes

Tropical and subtropical lowlands, including open woodlands, savannas, cerrado, gallery forests, and forest edges. They avoid dense, humid primary rainforests.

Geographic range

Central and eastern South America, including southeastern Peru, northern Bolivia, northern Argentina, eastern and central Paraguay, and eastern Brazil. A disjunct population also exists in the Guianas.

Elevation range

Typically found from sea level up to 1,750 meters (5,740 ft), but most common below 1,000 meters (3,300 ft).

Preferred environments

Prefers semi-open areas with scattered large trees for nesting and roosting, often near water sources. They are frequently seen in plantations, parks, and even suburban areas with suitable tree cover.

Behavior

Activity time

Diurnal, most active during the early morning and late afternoon.

Feeding habits

Primarily arboreal, foraging in the canopy and sub-canopy. They pluck fruits with their large bill, often tossing them into the air and catching them to swallow whole. They also use their bill to probe for insects, raid nests for eggs and nestlings, and catch small vertebrates. They are opportunistic feeders.

Social behavior

Usually seen in pairs or small family groups of 3-6 individuals. They are quite social and can be observed preening each other. They roost communally in tree hollows.

Flight pattern

Flight is typically undulating and heavy, characterized by several rapid wing beats followed by a glide. They are not strong fliers and prefer to hop between branches or make short flights between trees.

Migration pattern

Resident throughout its range; no significant migratory movements. They may undertake local movements in search of fruiting trees.

Territoriality

While not strictly territorial in the aggressive sense, pairs or small groups will defend their immediate nesting and roosting sites.

Breeding & reproduction

Breeding season

Varies geographically, but generally from September to February in the southern parts of its range (e.g., Brazil, Paraguay) and May to August in the northern parts (e.g., Guianas).

Nesting habits

Nests in natural tree cavities or old woodpecker holes, typically high up in large, dead or decaying trees. They do not excavate their own nests but may enlarge existing cavities. Both parents participate in nest preparation.

Clutch size

2-4 eggs, typically 3.

Egg description

Eggs are dull white, oval-shaped, and have a slightly granular texture. Approximately 40-45 mm in length.

Incubation period

17-18 days, primarily by the female, but the male also assists.

Fledging period

43-52 days. Chicks are altricial, born naked and blind, and require extensive parental care.

Parental care

Both parents share incubation duties and feed the chicks. They bring a variety of fruits, insects, and small prey to the nest. After fledging, the young remain with the parents for several weeks or months.

Where to find

Field tips

1. Look for movement in the canopy. Their large size and bright bill make them relatively easy to spot once you locate them. Scan the upper branches of large trees.
2. Listen for their calls. Their loud, croaking calls are often the first indication of their presence. Follow the sound to locate the birds.
3. Observe fruiting trees. Toco Toucans are primarily frugivorous, so checking trees laden with ripe fruit is a good strategy, especially early in the morning or late afternoon.
4. Be patient and quiet. While conspicuous, they can be wary. Move slowly and quietly to avoid startling them.

Fun facts

• The Toco Toucan's bill can be up to one-third of its total body length, making it the largest bill relative to body size of any bird.
• Recent research suggests the toucan's large bill plays a crucial role in thermoregulation, allowing it to dissipate excess body heat.
• Despite its formidable appearance, the bill is surprisingly delicate and made of keratin, similar to human fingernails, with a honeycomb-like internal structure.
• Toco Toucans are often seen 'bill-fencing' with each other, a behavior thought to be part of courtship or dominance displays.
• They have zygodactyl feet, meaning two toes point forward and two point backward, which is excellent for gripping branches.
