Orange-eyed Flatbill

The orange-eyed flatbill is about 13.5 cm (5.3 in) long; one male weighed 11.5 g (0.41 oz). The sexes have the same plumage. Adults have a cinnamon forecrown with olive-gray tips on the feathers. They have an olive-gray crown, buff lores, a pale eye-ring, and cinnamon-buff ear coverts. Their nape, back, rump, and uppertail coverts are pale olive-green. Their wings are dusky with greenish yellow edges on the greater coverts that form two wing bars and thin olive-green edges on the flight feather edges, some of which also have a cream far outer edge. Voice: The orange-eyed flatbill is best separated from other flatbills by its voice. One description of its song is "a rising series of short, rising-falling, raspy whistled notes: zreep zreeeep ZREEEP, final note often becoming clearer and more squeaky" and its call is "a rising-falling raspy whistle followed by a low chatter: ZREEE'chirr'rr".
