Military Macaw

Identification

The military macaw is a medium to large-sized parrot measuring 70 to 85 centimeters long with a wingspan of 99–110 cm. It is named after its distinctive plumage, which vaguely resembles a military uniform—predominantly green with bright-red patches on the forehead, light-blue and yellow flight and tail feathers. Like all macaws, it has a bare facial patch, whitish in colour with black striations, a large slate-grey to blackish bill, and a yellow iris.

Military macaws are visually similar to great green macaws but can be distinguished by their smaller size, completely black bill, and overall darker, deeper green plumage. The three recognized subspecies vary slightly in size and coloration, with the mexicana subspecies being the largest and militaris the smallest.

Range & Habitat

The military macaw is native from west-central Mexico south through northern Argentina and Bolivia. The three subspecies occupy distinct geographical ranges: A. m. mexicana in Mexico; A. m. militaris in Colombia, northwestern Venezuela, Ecuador, Peru, and Bolivia; and A. m. bolivianus in Bolivia and Argentina. Interestingly, the species is absent from Central America, possibly due to local habitat changes and competition with the closely related great green macaw.

These macaws typically inhabit tropical deciduous and semi-deciduous forests, where they are canopy-dependent species requiring large trees for feeding, breeding, nesting, and protection from predators and heat. They typically live at elevations of 600 to 1500 meters—higher than most other macaw species—though they may seasonally descend to lowlands with humid forests and thorny woodlands. They nest in tree cavities at least 15 meters tall and 90 centimeters wide, or more often in cliff faces over 600 feet above the ground.

Behaviour & Diet

Military macaws are highly social birds living in large flocks and are among the longest-lived parrot species, reaching 50–60 years in the wild. They are notably vocal and can often be heard long before being seen, making a variety of loud cracking and shrieking sounds including a distinctive loud kraa-aak call. Activity is most frequent in the morning and evening, indicating they are likely a crepuscular species.

Their diet consists mostly of seeds supplemented with fruits and leaves, though they have a somewhat narrow dietary range. Flocks forage together from dawn, often gathering at "macaw licks"—clay deposits along riverbanks and in the Amazon rainforest—which appear to remove toxins from seeds and vegetation while providing essential dietary salt. Pair-bonding includes grooming and regurgitation, with courtship beginning as early as March and breeding occurring between March and October, with fledging between January and March.

Best Time & Places to See It

Military macaws are most active and vocal during morning and evening hours, making these the best times for observation and photography. Their presence in large flocks and distinctive loud calls make them relatively conspicuous despite inhabiting the forest canopy. The species remains common in zoos and parks worldwide, but wild populations are concentrated in the Andean regions of Mexico, Colombia, Venezuela, Ecuador, Peru, Bolivia, and Argentina at elevations between 600 and 1500 meters in deciduous and semi-deciduous forests.

Photography Tips

The military macaw's striking green and red plumage and large size make it visually rewarding to photograph. Their crepuscular activity patterns mean that early morning and late afternoon light often provides optimal conditions. The birds' habit of calling frequently before appearing allows photographers to anticipate their presence. Photographing them in their natural canopy habitat at elevation can present challenges due to height and dense foliage, but their gregarious nature means multiple individuals may appear together, offering compositional opportunities. Their bare facial patches and yellow iris provide striking focal points for detailed portrait shots.
