it is under considerable threat. Unscrupulous bird traders may sometimes bleach or dye the feathers of more common parrot species, such as the white-fronted amazon in order to pass them off for sale as (more expensive) yellow-headed amazons. This cruel treatment is often fatal for the birds involved. As pets Though only captive-bred yellow-headed amazons may be owned, these are widely available (if somewhat expensive) and their personalities make them highly desirable pets; they have been kept as such for centuries because they are among the parrots that "talk" best. Their vocal abilities are generally bested only by the grey parrot and matched by similar species, such as the yellow-naped parrot. Yellow-headed amazons in captivity appear to have an affinity for both singing and the learning of song - and a naturally powerful, operatic voice. As in most amazons, nervous plucking of plumage is rare among this species. A generally recognized disadvantage of the yellow-headed amazon and its close relatives (such as the yellow-naped amazon) is hormonal aggressiveness, most notable among males in the breeding season. It is a member of the "Hot Three" (referring to the male bird's "hot" temper), along with the yellow-naped and blue-fronted. Yellow-headed amazons are known for being "one person birds" - bonding to one human, to whom they become fiercely loyal. It is possible, albeit difficult, to mitigate this behavior by ensuring that the bird receives regular and equal attention from other members of the household. Captive yellow-headed amazons are known for having a large appetite and an appreciation of a wide variety of foods. They are prone to obesity and nutritional deficiencies if the parrot's owner fails to provide adequate opportunities for play and exercise, and overindulges the parrot with treats and table scraps. The World Parrot Trust recommends that yellow-headed amazons be kept in an enclosure with a minimum length of 3 metres at a temperature no lower than 10°C.
