Wreathed Hornbill Identification Guide

Key Field Marks

• Size & shape: A large hornbill, roughly 75-100 cm long including a long, white-tipped tail; heavy-bodied with broad, deeply fingered wings that produce loud, audible whooshing in flight.
• Bill: Pale ivory-to-yellowish bill with a series of low transverse ridges ("wreaths") at the base — the feature that gives the species its name; it lacks the tall, solid casque of the Great Hornbill.
• Bare skin: Blue skin around the eye in both sexes and an inflatable, bare throat pouch.
• Sex differences: Males have a whitish-cream head and neck with a rufous crown and a yellow throat pouch crossed by a black band; females have an entirely black head and neck with a plain blue throat pouch (no black band).
• Body: Mostly black plumage with a white belly, vent, and tail (the tail may show a dark or plain look depending on light and wear).
• Behavior: Canopy-dwelling and highly frugivorous, especially on figs; travels in flocks, often at dawn and dusk between roost and feeding trees.

Separating It From Similar Species

• Great Hornbill: Much larger, with a tall, solid, boat-shaped yellow-and-black casque, black-and-white banded wings, and a white tail crossed by a bold black band — bigger and more boldly patterned than Wreathed Hornbill.
• Plain-pouched Hornbill: Extremely similar and best separated by pouch pattern — males lack the black band across the throat pouch that Wreathed Hornbill males show — and range (Plain-pouched is largely confined to the Thai-Malay Peninsula).
• Rufous-necked Hornbill: Both sexes show a rufous head and neck (not just the male's crown), and it inhabits higher elevation forest.

Habitat, Range & Season

• Found from northeastern India and Bhutan through mainland Southeast Asia to Sumatra, Java, and Borneo.
• Inhabits primary and tall secondary evergreen and semi-evergreen lowland and hill forest, generally below about 1,500 m, favoring areas with abundant fruiting fig trees.
• Resident and largely non-migratory, though it may make local movements tracking fruit availability; best looked for year-round at fruiting fig trees and forest canopy gaps.

Voice

• Loud, deep, barking or grunting calls, often a repeated "gak" or "kak" series, given in flight or from canopy perches.
• Flight itself is diagnostic even without calls — the deep, resonant whooshing of the wingbeats carries a long distance through the forest.
