White-throated Toucan

Identification

The white-throated toucan is a striking and unmistakable bird, measuring 50–61 cm in length. It displays the characteristic bold plumage pattern typical of large toucans: jet-black body feathers contrasted with a distinctive white throat and breast bordered below by a narrow red line. The rump is bright yellow, and the crissum (area around the cloaca) is red. The bare skin encircling the eye is blue. Most distinctive is the enormous bill: it features a yellow tip, upper ridge, and base of the upper mandible, with a blue base to the lower mandible. The remainder of the bill varies by subspecies, appearing mainly black in R. t. cuvieri and reddish-brown in R. t. tucanus, with intermediate populations showing mixed coloration. Males are noticeably larger and longer-billed than females, though otherwise the sexes are alike. Juveniles are shorter-billed with duller, more sooty-black plumage.

Range & Habitat

The white-throated toucan is found throughout the Amazon Basin of South America, including the adjacent Tocantins and Araguaia River drainages. The species shows a preference for tropical humid forest but also inhabits woodland and, locally, riverine forest within cerrado regions. Three subspecies are recognized across its range, each showing subtle variations in bill coloration and size.

Behaviour & Diet

White-throated toucans are highly vocal birds, producing one of the loudest calls among all toucans—a distinctive yelping "eeoo" or "hue hue" that carries far through the forest. They move through the canopy in small flocks or more commonly in pairs, using a heavy, weak undulating flight and typically traveling no more than 100 meters at a time. This species is primarily frugivorous, feeding extensively on arboreal fruits, though it will opportunistically take insects, lizards, eggs, and even small birds. Both sexes participate in breeding: eggs (numbering 2–6) are laid in an unlined cavity high in a decayed section of a living tree or in an abandoned woodpecker nest. Both parents incubate for 11–14 days and feed the chicks for approximately 6 weeks until fledging, continuing to provision juveniles for several weeks afterward.

Best Time & Places to See It

The white-throated toucan's loud, distinctive calls make it relatively easy to locate in suitable habitat. Travellers exploring the Amazon Basin, particularly in areas of tropical humid forest, have good chances of encountering this species. Their presence is often announced by their loud vocalizations before they are seen. Patient observers watching the forest canopy in the early morning hours, when toucans are most vocal and active, will have the best opportunities for sightings.

Photography Tips

The white-throated toucan's bold black and white plumage, combined with its striking colored bill and facial patches, makes it a rewarding photographic subject. Its relatively large size and arboreal habits mean it is often visible in the canopy, though the shaded forest interior may require higher ISO settings or faster shutter speeds. The bird's strong contrast between dark and light plumage can fool exposure meters; meter on the mid-tones of the body rather than the bright white throat. Patience is essential, as birds typically move through the forest rather quickly. Early morning light is ideal for capturing the vibrant yellow rump and brilliant blue eye-patch that distinguish this species.
