Guacamaya is the Spanish word for macaw, the largest parrots on Earth.1Conservation news. Pet trade and habitat loss decimating wild macaw populations In Mexico and Central America it most often points to the red, yellow and blue scarlet macaw. The Aztecs valued these birds above gold and collected their feathers as tax by the thousands.2Archaeology Southwest. What Is a Guacamaya? Facts About the Iconic Macaw Today many wild macaws are declining from trapping for the pet trade and loss of forest.3Conservation news. Pet trade and habitat loss decimating wild macaw populations
Which Bird Is a Guacamaya
Macaws are a group of big American parrots. The core group has eight living species and at least two that have gone extinct.4Wikipedia. Ara (bird) All of them live naturally only in the American tropics, from Mexico to South America. Other birds called macaws, like the hyacinth and the Spix’s macaw, belong to related groups. Spanish speakers use guacamaya for all of them and add a color: guacamaya roja for scarlet, guacamaya verde for the military or great green, guacamaya azul y amarilla for the blue-and-yellow.
The colors are also the easiest way to tell them apart. A scarlet macaw is mostly bright red, with yellow and blue on the wings and a bare white face. A blue-and-yellow has a blue back, a yellow chest and a white face with dark lines. Military and great green macaws are mostly green with a red forehead. All of them have very long, pointed tails, often as long as the body. Some places call smaller parrots loros or pericos instead, so size is the clue: a guacamaya is the big one.
The scarlet macaw itself comes in two forms. Scientists split it into two subspecies, a northern Central American form and a southern South American form, told apart by wing length and feather color.5Ibis. Genetic analysis reveals strong phylogeographical divergences within the Scarlet Macaw Ara macao A subspecies is a regional form of the same species that can still interbreed, and these two do: they meet and mix in southern Nicaragua and northern Costa Rica.6Ibis.

Colors and a Beak That Cracks Nuts
Feather color is part pigment, part structure. Parrots make their own yellow and red feather pigments, a kind found only in parrots.7PubMed Central. A molecular mechanism for bright color variation in parrots Blue is different: it comes from the structure of the feather scattering light, not from a blue pigment. Green patches combine the two, blue structure layered with yellow pigment.8PubMed Central. A molecular mechanism for bright color variation in parrots
The beak is among the strongest of any bird. A blue-and-yellow macaw’s jaw can bite with about 233 newtons of force, roughly the weight of a 24 kg bag pressing on one point.9PubMed. Morpho-functional analyses of the jaw apparatus in the Blue-and-yellow Macaw (Ara ararauna, Psittaciformes, Aves): Adaptations to feeding behavior That’s possible because three big jaw muscles pull almost straight across the jaw, giving maximum force.10PubMed. Morpho-functional analyses of the jaw apparatus in the Blue-and-yellow Macaw (Ara ararauna, Psittaciformes, Aves): Adaptations to feeding behavior The curved, pointed upper beak and strong lower jaw work like a pair of pincers, and ridges and bumps inside the beak grip hard shells so they crack instead of slipping.11PubMed. Morpho-functional analyses of the jaw apparatus in the Blue-and-yellow Macaw (Ara ararauna, Psittaciformes, Aves): Adaptations to feeding behavior A big macaw can crack palm nuts that people need a hammer for.
That power matters if you’re ever near a pet or rescued macaw. A bite from a large one can cause serious injury, so keep fingers away from strange birds. Macaws also use the beak like a third foot when climbing, and their feet have two toes forward and two back to hold food up to the beak.
What Guacamayas Eat and Why They Eat Clay
Macaws travel far for food. Flocks leave their roosts each morning and fly as far as 24 km a day to trees with ripe fruit.12San Diego Zoo Wildlife Alliance. Macaw They eat seeds, nuts, fruit and flowers, many of them hard or unripe.
Clay is on the menu too. Parrots in the Amazon gather at riverbanks to eat clay.13Biotropica. The Roles of Soil Characteristics and Toxin Adsorption in Avian Geophagy The clay they choose holds much more sodium than their food plants.14Biotropica. The Roles of Soil Characteristics and Toxin Adsorption in Avian Geophagy The same soils can soak up bitter plant toxins, and birds use the soils that do this best.15Biotropica. The Roles of Soil Characteristics and Toxin Adsorption in Avian Geophagy So clay probably gives them salt and protects their stomachs from seed poisons.16Biotropica.

Macaws act both as seed destroyers and as long-distance seed carriers.17PubMed Central. Seed dispersal by macaws shapes the landscape of an Amazonian ecosystem Of the palm fruits macaws picked in one study area, about 84 percent were carried away from the tree.18PubMed Central. Seed dispersal by macaws shapes the landscape of an Amazonian ecosystem They eat the pulp and drop the seed intact, so seeds usually land 30 to 50 m away, and sometimes as far as 1.2 km.19PubMed Central.

Pairs, Flocks and Loud Calls
Macaws usually keep one mate, though breakups and infidelity happen.21The Ara Project. Birds in Love Bonded pairs preen each other, share food and sleep side by side.22The Ara Project. Birds in Love Flocks contain friendship groups and plenty of flirting.23The Ara Project. Birds in Love
Calls tie the flock together. Chicks produce many call types that vary between groups.24Elsevier / Animal Behaviour. Vocal development and patterns of vocal variation inform conservation of a critically endangered macaw As adults they drop most of them, and their contact calls become very similar across populations.25Elsevier / Animal Behaviour. Vocal development and patterns of vocal variation inform conservation of a critically endangered macaw Matching calls likely helps birds join and stay in flocks.26Elsevier / Animal Behaviour. Vocal development and patterns of vocal variation inform conservation of a critically endangered macaw Loud, harsh squawks carry over the forest, mostly at morning and evening, and that volume is a big challenge for pet owners.
For nesting, macaws use holes in large old trees, which they do not dig themselves. Pairs usually raise one or two chicks at a time, and the chicks stay with their parents for months.
How Smart Are Macaws
In one puzzle, macaws had to build a tool to push food out of a tube. Three of seventeen learned to solve it reliably, and one blue-throated macaw got it right 12 of 16 times.27PubMed Central. Innovative problem solving in macaws Problem solving seems to vary a lot between individual birds.
In a home, this means pet macaws get bored and need puzzles and chewing toys. Bored birds may pluck their feathers or scream.
Many macaws can copy words, though usually less than African greys. Mimicry is social rather than an understanding of grammar, and wild macaws are not known to copy human speech.
Sacred Birds of the Maya and Aztecs
Peoples of Mexico and Central America have traded macaws and used their feathers in rituals for more than 2,000 years.28Science. Early Native Americans Imported Bred Scarlet Macaws, DNA Reveals For over a thousand years they were carried north to what is now the US Southwest in exchange for turquoise.29Science.

Why Wild Macaws Are in Trouble
Wild macaws are declining because of collecting for the pet trade, poaching and habitat loss.34Conservation news. Pet trade and habitat loss decimating wild macaw populations They live long, breed slowly, form lasting bonds and need tree holes to nest, so taking eggs or chicks hits populations hard.35PubMed Central. From Forest Extraction to Digital Markets: Illegal Macaw Trade and Adaptive Monitoring for Forest Wildlife Resilience In a Brazilian national park, blue-and-yellow macaws face both road deaths and nest poaching.36Diversity. Assessing the Relative Impacts of Roadkill and Nest Poaching on the Population Viability of the Blue-and-Yellow Macaw, Ara ararauna (Aves: Psittaciformes), in a Brazilian National Park
Tree holes are scarce because only big old trees have cavities large enough. Logging removes these first, and poachers sometimes cut nest trees to reach chicks.
For travelers and buyers, the rule is simple: never buy a bird or feathers sold at markets or roadsides. Wild-caught macaws often die in transport. Legal pets should come from documented captive breeders, and wildlife sales are worth reporting to local authorities.
Bringing Guacamayas Back
Releases of captive-bred birds can work. In Palenque, Mexico, 92 captive-bred scarlet macaws were released in a year, and 92 percent survived the first months.37Tropical Conservation Science. Reintroduction of the Scarlet Macaw (Ara Macao Cyanoptera) in the Tropical Rainforests of Palenque, Mexico: Project Design and First Year Progress Artificial nests can help released birds breed.38Journal for Nature Conservation. Nest site selection and efficacy of artificial nests for breeding success of Scarlet Macaws Ara macao macao in lowland Peru In Los Tuxtlas, Veracruz, returned scarlet macaws now draw ecotourism and local pride.39Journal of Ecotourism. Slow but sure assimilation to culture and ecotourism of reintroduced scarlet macaws in Los Tuxtlas, Veracruz, Mexico
The effort reaches beyond scarlets. Spix’s macaw, extinct in the wild, was released in Brazil in 2022, and one pair raised chicks in a nest box.40Diversity. Reintroduction of the Extinct-in-the-Wild Spix’s Macaw (Cyanopsitta spixii) in the Caatinga Forest Domain of Brazil In Guatemala, vets raise and release rescued chicks and track them.41Wildlife Conservation Society.

Where to See Guacamayas in the Wild
Large macaws can move up to 150 km from nests outside breeding season, and their range grows about 24 times larger then.42Avian Conservation and Ecology. Satellite telemetry reveals complex migratory movement patterns of two large macaw species in the western Amazon basin Sightings can therefore change by season. Early morning flights to feeding trees are the best time to watch. Good places to look include Palenque and Los Tuxtlas in Mexico, Copán in Honduras, Costa Rica’s Pacific coast parks, and the Tambopata clay licks in Peru. Bring binoculars and stay quiet, and never feed wild macaws.
