Blue-crowned Trogon is fairly uncommon throughout its large range. They occur in lowland humid forest, particularly in várzea, and seem to prefer edges and second growth. Like other trogons, they forage on small arthropods and fruit, often perching motionlessly for long periods of time. To distinguish Blue-crowned from other trogons, note especially the red belly and black tail fairly barred with white, field marks that are present in both sexes. Males also have a blue head and breast, whereas females are gray throughout their head, breast, and back. Their voice is a series of fairly high yelping notes that often crescendos in the middle. The of the Blue-crowned Trogon is a tunnel dug into an active arboreal termite mound.
