Red-shouldered Macaw

Fascinating facts about the Red-shouldered Macaw

• First described in 1758, it now sits alone in its own genus, a taxonomic journey spanning centuries. Linnaeus gave it the name Psittacus nobilis, but in 1912 Ridgway created the genus Diopsittaca just for this species, making it the sole member. This unique classification highlights its distinct evolutionary path among the otherwise massive macaw family.
• Only 30 cm long, the red-shouldered macaw is the smallest macaw, barely the size of a common parakeet. At just 165 g (5.8 oz) it weighs, yet it carries the same bold colors and long tail of its giant cousins.
• Three named subspecies share a single species. The noble macaw, Hahn's macaw, and the long-winged macaw all belong to Diopsittaca nobilis, but the long-winged form sports noticeably longer wings while otherwise matching the noble type.
• A single clutch holds just three or four white eggs. The female spends about 24 to 26 days incubating them, then the chicks remain in the nest for roughly 54 days before fledging.
• First described by Carl Linnaeus in 1758, this bird now sits alone in the genus Diopsittaca, created by Robert Ridgway in 1912. Its scientific name blends Greek "dios" (noble) with "psittakē" (parrot), echoing the regal red wing coverts that appear only after the birds reach puberty.

About the Red-shouldered Macaw

The Red-shouldered Macaw (Diopsittaca nobilis) is a striking parrot, renowned for its vibrant plumage that features a rich blend of green, blue, and the characteristic red shoulder patches that give it its name. This medium-sized bird, measuring about 30 cm in length, possesses a strong, curved beak, perfectly adapted for its diet in the wild. Native to the tropical forests of South America, particularly in regions of Brazil, Bolivia, and Paraguay, these macaws thrive in subtropical and tropical moist lowland forests, where they can find ample food and nesting sites among the dense foliage. Their social nature often sees them forming small flocks, engaging in playful aerial displays and vocalizations that echo through the canopies, creating a lively atmosphere in their habitat. A surprising trait of the Red-shouldered Macaw is its remarkable ability to mimic sounds, including human speech, which has made them popular as pets despite their complex social needs that are often unmet in captivity. In the wild, Red-shouldered Macaws primarily feed on seeds, fruits, and nuts, showcasing their adept foraging skills as they navigate the treetops. Their diet plays a crucial role in seed dispersal, contributing to the health of their ecosystem. These birds exhibit strong pair bonds, often mating for life, and are known to engage in elaborate courtship displays. Their nesting habits involve creating cavities in trees, where they lay a clutch of two to four eggs. The nurturing of their young is a shared responsibility, with both parents involved in feeding and protecting their chicks, highlighting their deep familial bonds as they raise the next generation of these enchanting parrots.
