Their upperparts are grayish olive with a hidden white patch between the scapulars. Their wings are blackish with wide chestnut-rufous edges on the flight feathers and white tips on the coverts. Their tail is rufous-olive with narrow white tips on the feathers. Their throat and upper breast are white and the rest of their underparts mostly yellowish. Voice: The spot-breasted antvireo's song is a "rather hurried series of some 20 mellow, slightly staccato, rising and falling notes, the last 3-5 accelerated". Its calls include a "short, upslurred 'chirr', nasal 'qwark', and a series of three notes with first two on same pitch".
