Crimson-collared Tanager is beautiful and easily identified black and red bird with a strikingly pale bill. This species is endemic to Middle America, where it is found along the Atlantic slope from southeastern Mexico south to Panama. The plumage is identical in both sexes, although juveniles are much duller, with the red parts being brick-colored. There are few, if any, realistic risks of confusion with other species. This tanager generally occurs in pairs for most of the year, although it forms small groups for brief periods post-breeding. Like other species of Ramphocelus, Crimson-collared Tanager occurs in the lowlands, inhabiting shrubby borders and other more open wooded habitats below 1100 m.
