Blue-crowned Trogon is fairly uncommon throughout its large range. It occurs in lowland humid forest, particularly in várzea, and seem to prefer edges and second growth. Like other trogons, it forages 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. The male also has a blue head and breast, whereas females are gray throughout their head, breast, and back. The song is a series of fairly high yelping notes that often crescendos in the middle. The nest of Blue-crowned Trogon is a tunnel dug into an active arboreal termite mound.
