Great Antshrike

The Great Antshrike is a large, distinctive member of the antbird family, notable for its striking sexual dimorphism: males are boldly patterned in black and white, with a black crown, back, and bushy crest contrasting against clean white underparts and white-edged wing feathers, while females are entirely different, rich rufous-chestnut above with buffy-orange underparts and a similar bushy rufous crest. Both sexes share a piercing red eye and a heavy, hook-tipped bill typical of antshrikes.

Despite its bold coloring, the species is notoriously skulking, preferring to remain hidden within dense tangles and thickets rather than venturing into the open, so that its presence is often revealed first by its distinctive voice rather than by sight.

Key field marks

• Males: black crown, back, and bushy crest; white underparts and white-edged wings
• Females: rich rufous-chestnut upperparts, buffy-orange underparts, rufous crest
• Both sexes: bright red eye, heavy hook-tipped bill
• Skulking behavior within dense undergrowth

Similar species

• Barred Antshrike shows fine black-and-white barring in males rather than solid black-and-white blocks, and is smaller overall.
• Female Great Antshrikes can resemble other large rufous antbirds but the red eye and bushy crest are useful distinguishing features.

Habitat

Inhabits dense undergrowth, thickets, vine tangles, and forest edge, including secondary growth and riverine scrub.

Range

Widespread from Mexico and Central America through much of tropical South America, including the Amazon basin, extending south to Argentina.

Migration

Resident and non-migratory throughout its range.

Behavior

Skulking and often difficult to observe, staying low within dense vegetation; pairs may duet, calling back and forth from within cover.

Voice

A distinctive, accelerating series of low, hollow notes, often ending in a sharp, growling or nasal note, frequently given as a duet between paired birds.

Feeding

Feeds on insects and other arthropods, and occasionally small vertebrates such as lizards, gleaned and captured within dense low vegetation; not a dedicated ant-following species despite the family name.

Nesting

Builds an open cup nest low in dense vegetation or a vine tangle; both parents share incubation and care of the typically 2-egg clutch.
