Spotted Antbird Identification Guide

Key Field Marks

• Size & shape: Small, around 4.7 inches (12 cm), with a short tail and the alert, upright posture typical of antbirds.
• Male plumage: Rich rufous-orange crown and upperparts; white underparts boldly marked with round black spots across the breast and flanks, giving a neat polka-dot look; black-and-white streaked or barred pattern on the face/nape area.
• Female plumage: Similar rufous upperparts but underparts are buffy-orange with fine dark barring/streaking rather than bold round spots.
• Behavior: A classic army-ant-following species, staying low over swarms to snatch flushed insects; often perches sideways on vertical stems, flicking wings and tail; usually in pairs.

Separating It From Similar Species

• Spotted-backed and other spotted antbirds — many antbird species share "spotted" in the name and pattern; Spotted Antbird's combination of rufous-orange upperparts with bold black spots on a clean white breast (male) is diagnostic within its Central American/Chocó range.
• Bicolored Antbird — larger, plainer, without the spotted underparts, also an ant-follower and often present at the same swarms.
• Ocellated Antbird — much larger, with bright blue facial skin and scaled/ocellated (not simple round-spotted) underparts.
• At an ant swarm, size, the bold white-with-black-spots breast, and rufous back reliably separate male Spotted Antbird from co-occurring species.

Habitat, Range & Season

Resident in humid lowland and foothill forest from Honduras and Nicaragua through Costa Rica, Panama, and into western Colombia and Ecuador (Chocó region). Found in forest understory, especially where army ant swarms are active, up to around 1,000 m. Non-migratory; pairs hold territories and track ant swarm activity within them.

Voice

A thin, high, accelerating series of sharp notes, often speeding into a brief trill; also gives sharp single "chip" call notes while foraging at swarms.
