The blue-and-yellow macaw, also known as the blue-and-gold macaw, is a magnificent Neotropical parrot that captivates with its striking coloration. The dorsum is predominantly a vivid blue, while the venter boasts a light yellow or orange hue. A gradient of green adorns the top of its head, adding to its vibrant appearance. This species is one of the larger macaws, with a length of 76β86 cm (30β34 in) and a weight ranging from 0.9 to 1.5 kg (2β3 lb).
To identify the blue-and-yellow macaw, look for its bright aqua blue feathers on the upper body, contrasting with a deep yellow or light orange underside. The head is a distinctive lime color. The beak and feathers under the chin are black, while the feet are gray with black talons. A notable feature is the white skin on its face, which is sparsely feathered, creating a striped pattern around the eyes. The irises of this macaw are a pale light yellow.
These macaws inhabit a variety of environments, including forests (notably varzea), woodlands, and savannahs. They are also found in open sections of terra firme or unflooded forest and have adapted to urban areas where they nest in ornamental palms.
The blue-and-yellow macaw's range spans tropical Central and South America, including Panama, Trinidad and Tobago, Colombia, Suriname, French Guiana, Venezuela, Guyana, Peru, Brazil, Bolivia, Ecuador, and Paraguay. It has a limited presence in Central America, restricted to Panama.
In the wild, blue-and-yellow macaws can live up to 30 to 35 years and reach sexual maturity between 3 and 6 years. They exhibit strong bonding behaviors and are known for their powerful beaks, which are used for breaking nutshells and climbing trees. These macaws are also adept at feeding on a variety of foods, including seeds, fruits, vegetable matter, bark, leaves, insects, snails, and small animals.
The blue-and-yellow macaw is known for its loud vocalizations, which include "flock calls" that are a natural part of their behavior.
These macaws are monogamous, generally mating for life. They prefer to nest in dead palms, particularly Mauritia flexuosa. The female lays two or three eggs and incubates them for about 28 days. Typically, only the dominant chick survives, with the others perishing in the nest. Fledging occurs approximately 97 days after hatching.
The blue-and-yellow macaw is listed as Least Concern by BirdLife International, with a wild population believed to be above 10,000 individuals. However, it is on the verge of extirpation in Paraguay and is in decline overall. It is listed on CITES Appendix II, indicating that trade is restricted.
The diet of the blue-and-yellow macaw includes nuts, seeds, fruits, vegetable matter, bark, leaves, insects, snails, and small animals. They use their powerful beaks to break open nutshells and forage for food.
In captivity, these macaws require attention and can be quite vocal. They need ample space to fly and can live up to 60 years or more with proper care. Their behavior includes "screaming" for attention, loud vocalizations, and destructive chewing. They are known to blush and fluff their facial feathers when interacting with humans, possibly indicating their emotional state.
