The orange-eyed thornbird is 16 to 18 cm (6.3 to 7.1 in) long and weighs about 21 to 27 g (0.74 to 0.95 oz). It is a medium-sized thornbird. The sexes have the same plumage. Adults have an indistinct rufous-brown supercilium, darker brown lores, and a darker brown stripe behind the eye on an otherwise rufescent-brownish face. Their forehead and forecrown are bright rufous. The rest of their crown, their back, and their rump are dark brownish olive, and their uppertail coverts a chestnut-tinged brownish olive. Voice: The orange-eyed thornbird's song is a "slow, descending series of up to 15 sharp, ringing tones". It has also been described as "a series of introductory notes on same pitch followed by descending series of loud notes, 'chree, chree, chree-tsrééeh-tsrééeh-tsrééeh' ". It is usually sung from a perch and sometimes as a duet by a pair.
