The crimson-backed tanager (Ramphocelus dimidiatus) is found in Colombia, French Guyana, Panama, and Venezuela. Its natural habitats are subtropical or tropical moist lowland forests and heavily degraded former forest. It has scarlet flanks and rump grading into deep velvety crimson head and back. It travels in noisy flocks in scrub, edge, and secondary growth and is generally common, particularly in areas with human activity.
