Blue-and-yellow Macaw (also known as the Blue-and-gold Macaw)

This is a long, elegant tail feather from one of the most iconic parrots in the world. The Blue-and-yellow Macaw is a massive bird with a wingspan of nearly 4 feet, characterized by bright blue upperparts and golden-yellow underparts. It has a powerful black bill, white skin facial patches, and a loud, raucous call used to communicate over long distances in the rainforest canopy.

Vibrant structural blue on the dorsal (upper) surface, transitioning to a greenish-teal hue toward the base; the ventral surface (not fully visible but implied) is typically olive-yellow or golden-yellow

Primarily pennaceous with tightly interlocked barbs; small plumulaceous section near the calamus (base)

Strong, central rachis transitions from a dark/blackish color at the tip to a lighter, translucent cream near the base; barbs are densely packed and angled steeply toward the tip

Smooth, glossy, and relatively stiff; the surface exhibits a waxy, water-resistant quality typical of large tropical parrots

Tail (Rectrices); determined by the significant length, relative stiffness, and the gradient of blue coloration commonly found in the long tail streamers

Characteristic brilliant 'macaw blue' structural color, elongated narrow shape, and a dark rachis fading to light at the quill

Humid lowland forests, woodlands, and swampy savannas, often near rivers or palm groves

Resident across South America, from Panama and Colombia south to Brazil, Bolivia, and Paraguay; introduced populations exist in Florida, USA

Apex seed predator and occasional seed disperser; they play a vital role in tropical forest dynamics by processing large fruits. Classified as 'Least Concern' by IUCN, but populations are declining due to habitat loss and the illegal pet trade.

Blue-throated Macaw (Ara glaucogularis) feathers are very similar but often have a different tail gradient; Hyacinth Macaw feathers are much darker, deep cobalt blue without the green-gold transition.

Blue-and-yellow Macaws are highly intelligent and can live up to 60-80 years in captivity. They often mate for life and are known to eat clay at 'macaw licks' to neutralize toxins from the seeds and fruits they consume.

Historically significant to indigenous Amazonian tribes for ceremonial headdresses and tribal art. Widely used in modern times for high-end fly-tying (salmon flies) and luxury millinery, though trade is regulated.

Look for these long streamers near tall palm trees or riverbanks in South America during the molting season. In urban environments, they are frequent finds near large outdoor aviaries or botanical gardens where feral populations exist.

Good to Fair; some wear is visible along the vane edges (feather fraying), suggesting it was molted naturally or handled. No visible parasites or fault bars
