The Blue-banded Toucanet resembles the more familiar widespread Emerald Toucanet (Aulacorhynchus coereicinctus), but is found in the subtropical and lower temperate zone on the east slope of the Andes from central Peru south into Bolivia. Blue-banded is a green toucanet that lacks the yellow culmen of Emerald, has a white throat, and displays a somewhat difficult to see blue band across the breast. It is replaced at lower elevation in the upper tropical zone by Chestnut-tipped Toucanet (Aulacorhynchus derbianus), which is smaller, has a reddish base and tip to the bill, and lacks the red rump of Blue-banded. They travel in pairs or small groups, and are often found foraging on the catkins of Cecropia trees. Vocalizations of Blue-banded more harsh and raspy than the “nasal” calls of Chestnut-tipped. Like other toucanets, they nest in tree cavities.
