Mini macaws are generally considered those types of macaws that are less than 20 inches (50 cm) in length. There are several types of mini macaws. Some of the most common include the severe macaw, the Hahn's macaw, the yellow-collard macaw, the noble macaw, and the Illiger's macaw. Mini macaws are usually much like full-sized macaws in intelligence and temperament, though their size may make them easier to care for. Most types of mini macaw live for about 20 to 30 years, and are considered intelligent, affectionate, playful, and trainable.
The yellow-collared macaw is one of the larger mini macaws, with an adult length of about 15 inches (38.1 cm). Birds of this breed can become very attached to their human owners, and generally require a lot of human interaction. They have a reputation for attempting to escape from their cages, and are considered very intelligent. The yellow-collared macaw typically has green feathers all over its body, with a yellow stripe across the back of the neck.
