令人惊叹的事实
- Blue-throated macaws are one of the most endangered macaw species in the wild. As of 2021, there were an estimated 200 – 300 mature individuals living in a small area of north central Bolivia.
- They were rediscovered from extinction, after scientists unexpectedly discovered a wild population in 1992.
物理特征
Blue-throated macaws are approximately 33 inches long with a wingspan of 3 feet and weighing around 1.5 pounds. Males are just slightly larger than females, but similar in all other aspects. The have bright blue feathers on their head and wings, bright yellow feathers on their chest and tail, and a distinctive patch of blue on the throat, which gives the species its name and differentiates it from the similar looking blue and yellow macaw. They have five or six stripes on their face, below the eye, with the pattern unique to each macaw. As they mature, their eyes change color and can be used to determine the age of an individual.
They can live up to 50 years under human care.
栖息地
Blue-throated macaws are found in forests and savannas.
饮食

范围
They are found in a small area of north central Bolivia.
社交行为
Blue-throated macaws live in small groups. They are monogamous and will nest in a hole in a palm tree, with competition for the best nesting spots. While the female incubates the 2 – 3 eggs, the male will feed her. Once the chicks hatch, both parents will feed the chicks. Juvenile blue-throated macaws live with their parents for up to one year. Young become sexually mature at 5 years. They are active during the day and have a loud alarm call. Parents will also vocalize to chicks and partners. Mating couples will preen to maintain pair bonds.
