Their upperparts are mostly cinnamon-rufous. Their wings are mostly dusky cinnamon with dusky rufous coverts and dusky flight feathers with light cinnamon-rufous edges. Their tail is cinnamon-rufous. Voice: The chestnut-crowned becard's song is a "simple series of 4-5 very high weeu--- notes without intervals".
