Behavior/Health Concerns:  Hawk-headed parrot are prone to biting and excessive aggressiveness, usually due to being startled or feeling insecure. Move cautiously and let your hawk head learn to trust you through established interaction. Without proper socialization when they are young and hand-fed, the hawk-headed parrot can be difficult to deal with during adulthood. Hawk heads can become very territorial around their cage or aviary. Feed your hawk-headed parrot a diet consisting of both pellets and seeds as well as a wide array of fresh fruits and vegetables, such as papaya, grapes, oranges, apples, carrots and beets.
