Hahn's Macaw

Overview

Hahn's Macaw, also called the Red-shouldered Macaw, is the smallest of the true macaws, roughly the size of a large parakeet rather than the imposing birds most people picture when they think of macaws. It ranges across northern and central South America in savanna and open woodland habitats.

Despite its diminutive size, it shows the classic macaw silhouette in miniature, with a bare-skinned face patch and a long pointed tail.

Feather Identification

• Body feathers: Bright grass-green over most of the body, brighter and cleaner in tone than many larger green macaws.
• Shoulder patch: A small but distinctive patch of red feathers at the bend of the wing (underwing coverts), visible when the wing is spread or in flight.
• Head feathers: A subtle blue wash across the forehead and crown, more pronounced in good light.
• Tail feathers: Long relative to body size but much shorter in absolute terms than other macaws, tapering to a point, mostly green with a bluish tip.
• Compared to similar species: The similarly small Chestnut-fronted Macaw shows a brown forehead patch rather than blue, and both are best separated from parakeets by their bare white facial skin patch.

Plumage Notes

Sexes look alike, both bright green with the blue forehead wash and red shoulder patch. The bare facial skin is whitish and unfeathered, a hallmark of macaws even at this small size.

Juveniles are duller green with a less defined shoulder patch, brightening after their first molt. Molt occurs gradually throughout the year.

Habitat & Range

Hahn's Macaw is found across northern and central South America, including parts of Venezuela, the Guianas, Brazil, Bolivia, and Paraguay. It favors savanna woodland, gallery forest edges, and areas with scattered palms, often at lower elevations than some of its larger relatives.

The species is generally resident, though flocks may shift locally with seasonal fruiting and seeding patterns.

Behavior & Field Notes

Hahn's Macaws are social and are usually seen in small flocks, flying fast and direct with quick wingbeats compared to the slower flight of larger macaws. They feed on seeds, fruit, and blossoms in the canopy and forest edge.

They nest in tree cavities, sometimes in old woodpecker holes, and can be quite vocal, giving high-pitched, screeching calls that are noticeably shriller than the deep calls of large macaws.
