Clements recognises the following subspecies [1]:

D. n. nobilis: Eastern Venezuela to the Guianas and northern Brazil north of the Amazon. [the smallest subspecies with all-black bill]
D. n. cumanensis: "Southern Red-shouldered Macaw". Northern Brazil south of lower Amazon to north-eastern Brazil [larger than nobilis; bill with whitish upper mandible]
D. n. longipennis: "Southern Red-shouldered Macaw". South-eastern Peru and north-eastern Bolivia to central and south-eastern Brazil. [larger than cumanensis; bill with whitish upper mandible]

Tropical lowlands, savanna, marshes, gallery forest.

The diet includes seeds, berries, fruits, and blossoms. The usually feed in the tops of trees and bushes.

They usually nest in a tree hole. The 2-5 eggs are laid two days apart and are incubated for about 24 days. The young fledge at around 8 weeks.
