The Crimson-collared Tanager is beautiful and easily identified black and red bird with a strikingly pale bill that is endemic to Middle America, where it is found from southeast 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 is generally found in pairs for most of the year, although it forms small groups for brief periods post-breeding. Like other Ramphocelus, it is a bird of low levels, inhabiting shrubby borders and other more open wooded habitats below 1100 m.
