Birds, like people, can be allergic to a wide variety of foods, the most common being: peanuts; wheat, pocket option app for pc and soy products; eggs; any artificial or chemical product like colorings, flavorings and preservatives but they can also be allergic to strawberries, oranges and any other number of things that we would normally consider ‘safe’.
It is always recommended that birds eat a completely organic diet (this includes distilled, spring or purified water for drink and bath) but for presenting symptoms of FDB, it is imperative that all allergens be removed from their diet. Take into consideration that most commercial bird food like pellets, treats, pasta, cereals, etc have peanuts and/or wheat products so they should be eliminated from the birds diet and, each element slowly re-introduced until it is determined to be safe for the bird.

There is a number of products that are now being offered to treat food allergies, like Allergy Supplement™, Noni juice (Tahitian only), MSM , and Una de gato (cat’s claw), and, of course, antihistamine (hydroxyzine dosed to effect in the water).

High zinc or lead levels in the bloodstream have been recognized as causing feather abusive behavior. These metals enter the parrot’s digestive tract when the bird mouths certain items. Most of the cases of metal toxicity of which I hear concern cockatoos, who are exceptionally “beaky” birds by nature and are often fascinated by metal objects.

Zinc is present in many forms in the parrot’s environment. Many of the fasteners used to hold toys to the cage are galvanized metal, which is coated with zinc. Bells on toys can contain zinc. The powder coating on some of the less expensive cages has been shown to contain zinc. One feather picking Umbrella Cockatoo who exhibited very high levels of zinc in his blood had a habit of drinking from the bathroom faucet. While doing so, he would scrape the inside of the fixture with his beak. The most frequently cited sources for lead toxicity include the leading on stained glass windows and other items. This is quite soft and readily yields to the pressure of a curious beak. The small seed beads used to make jewelry often contain lead. Some parrots have increased levels of lead from ingesting the weights that are placed in the
