Rainforest swamp riverbanks that inhabit tropical and subtropical areas prefer to live in open forests, avoid humid forests all the year round, and prefer to live in palm forests with rich stone fruits, usually in pairs or in small groups.Like the hyacinth macaw in the wildPalm treeThe turquoise macaw prefers a kind of hard seed called "Yata Palm"（Butia yatay）The seed of.In addition, mature or immature fruits, berries and vegetables on the tree are also the parrot's secondary food.The breeding speed is very slow. A pair of parrots only produce 1-2 eggs every year.Nests are built in tree holes or other bird caves.[3][5]
They live near the cliffs of subtropical coastal forests, and a small number of turquoise macaws live in areas with lush tropical savannah and palm trees.The records of several contemporary naturalists show that they are very sociable.The basic diet mostly comes from nuts of the Butia yatay tree, andLears Macaw The palm nuts eaten are about the same size and have the same beak size.Nesting on steep banks or cliffs is also common in tree holes.[3][5]

The turquoise macaw became very rare in the 19th century due to its capture activities and habitat destruction.In the 20th century, only two credible records of field discoveries were recorded.In the 1990s, ornithologists went to southern Paraguay to investigate, but found no evidence that any species still existed.
In addition to agricultural development, palm trees have been cut down extensively, resulting in habitat loss.Its striking appearance and huge size make it the main target of hunters. Even young birds are caught and sold to the pet market.
The last known turquoise macaw artificially raised in the world died in 1938 in the capital of ArgentinaBuenos AiresThe only zoo left is ArgentinaNatural History MuseumA dried specimen of.[4]
