Double Yellow Amazon Distribution / Range

The Yellow-headed Amazons are endemic to Guatemala. They were previously also found along the coastal slopes of Mexico from the Tres Marías Islands and Jalisco to Oaxaca and from Nuevo León to northern Chiapas and southwestern Tabasco, as well as a disjunct area including most of Belize, as well as northwestern Honduras. They inhabit riparian forest and areas with scattered trees, as well as evergreen forest in Belize and mangroves in Guatemala. Introduced populations can be found in Stuttgart, Germany where a population of over 50 individuals resides. Smaller introduced populations are to found at Imperial Beach, San Diego and Santa Anna both in Southern California.

These parrots occurs in singly or in pairs, in small groups, and occasionally in big flocks.

Their numbers have been reduced drastically—by 90 percent, to 7,000, from the mid 1970s to 1994, and by 68 percent from 1994 to 2004. The main reason being trapping for the pet trade and habitat destruction.


Physical Description

The Yellow-naped Amazon averages 15 - 17 inches (38–43 cm) in length (including tail). When excited all feathers of the neck and crown are raised, making the head appear double in size. They have a robust build, rounded wings, and a square tail. The body is bright green, with yellow on the head, dark scallops on the neck, red at the bend of the wing, and yellow thighs. The flight feathers are blackish to bluish violet with a red patch on the outer secondaries (shorter, upper "arm" feathers). The base of the tail also has a red patch, which is usually hidden. The outer tail feathers have yellowish tips. The bill is horn-colored, darker in immatures of the Belizean and Honduran subspecies. The eye ring is whitish in Mexican birds and grayish in others. Male and female look alike.

Immatures have less yellow than adults; they attain adult plumage in 2 to 4 years. '

Mutations: Lutino and blue mutations and myriad variations have been produced in aviculture. Below is a photo of Tommy - a beautiful and rare mutation double headed amazon. According to his owners, he is a great pet. He likes attention and wants to be close to the action. He can be very vocal screaming "come here, come here!" Like just about all parrots, he likes to discipline by biting from time to time. Training is recommended to prevent undesirable behavior.

Yellow-headed Amazon (Amazona oratrix) or Double Yellow-headed Amazon Personality / Pet Potential:

These beautiful parrots are very intelligent and imaginative birds that are easily tamed as they enjoy human company. Therefore, they have grown to be very popular in the pet bird trade. They are considered very good talkers and singers.

Some become nippy and they may not be the right pet for the casual owner who doesn't want to take the time to learn about parrot behavior and training. They are generally known to be noisy, thus they may not be suitable for individuals who are intolerant to noise. As is the case with most mid-size to large parrot, they can be destructive unless their energy is redirected at chewing toys, natural and non-toxic branches, and training of tricks.
