The Crimson-mantled Woodpecker is widely distributed and is fairly common across its range. Nonetheless, most aspects of its natural history are very poorly known. There is essentially no information on its nest or reproductive biology, and very little information on diet. There also is no information on such topics as age at first breeding, life span and survivorship, dispersal, population regulation, molts, territoriality and population density, and sexual behavior. Finally, the significance of apparent geographic variation in voice in the Crimson-mantled Woodpecker remains unexamined; but the possibility exits that at least one subspecies (atriceps) may be divergent enough to represent a separate species.
