The Blue-crowned Motmot has a broad geographic distribution, and usually is fairly common throughout its range. Nonetheless this species has attracted relatively little attention for many years. There is no information on such topics as age at first breeding, life span and survivorship, dispersal, population regulation, molts, territoriality and population density, sexual behavior, and responses to predators. There also are only a few studies of the diet and reproductive biology of the Blue-crowned Motmot. Finally, the taxonomic relationships of the northern "blue-crowned" subspecies (coeruliceps) to the three other subspecies (the lessonii group) merit further investigation.
