Input (English): [header] How to deal with an aggressive amazon parrot [title] Check your bird's environment and diet to make sure they're correct. [step] Your parrot should eat enough to maintain a relatively constant weight. If your aggressive amazon often empties its food and water bowls completely, try giving it a bit more food and water next time you feed it. <sep> (A) [substeps] Avoid giving your parrot bird micropapers that contain viruses and bacteria that may cause behavioral changes, including penatory illnesses and injury. Do not give your parrot tiny white paper that holds bacteria or parasites. (B) [substeps] The amount of food a parrot needs may vary with the season. Since amazon parrots include dozens of species, each of which has a different average mass, it is impossible to generalize about how much your pet should weigh. (C) Otherwise, this could be the result of continued weight loss or existing behavioral problems. [substeps] If your aggressive amazon seems content munching on cardboard, make sure they've mastered the habit of eating in locations with the most easy access to solid food. (D) [substeps] Looking in the corners of the cage is another good place to start noticing a difference in your bird's behavior. If your bird starts squawking, growling, or yelling, gently remove it from your handling.
