1. Caffeine-containing drinks: Caffeine parrots cannot metabolize, and chocolate will poison parrots. This is because people and parrots have different digestive abilities, and the result of digestion leads to poisoning. Bread chocolate and dark chocolate are more toxic than milk chocolate. So don't feed your parrot any kind of chocolate.

2. Milk: The sugar in milk is called lactose. Mammals digest milk sugar because they digest yeast and lactose. Parrots obviously lack lactose, so they can't digest any dairy products, including lactose. If the lactose content in the diet reaches 10 to 30%, it will cause parrot diarrhea. If the product contains dried milk lumps or dried whey, people may not be able to digest these things, which is called lactose discomfort.

3, alcohol: alcohol will damage the parrot's liver, alcoholic drinks will reduce coordination, leading to death. So parrots should avoid touching any alcoholic products. Some seeds or stones can also cause poisoning. The core of apple contains cyanide, so the core should be removed before feeding. Cherry, plum, almond and peach can all be provided to parrots, but the seeds in the stone will produce cyanide (release cyanide).

4. Salt (sodium chloride): Parrots cannot excrete salt in human food. Eating a lot of salt in human food will poison parrots. Pathogen: parrot's feed contains too much salt, or eats a lot of salt by mistake, which will cause salt poisoning. The main reason is that the water balance of various tissues of the body is destroyed, and excessive sodium ions in salt cause the kidneys and intestines to be unable to discharge excessive water from the blood.

5. Apple seeds: A small amount of cyanide in apple seeds will poison your parrot.

6. Solanaceae plants, such as tomatoes and potatoes, contain solanine in green parts such as leaves, stems, vines and buds; Solanine can cause severe stomach pain, nausea and vomiting in birds.

7. Edible mushrooms belong to fungi. Birds are very sensitive to fungi. There are no enzymes that can decompose many different compounds in edible fungi. After eating, they can cause food poisoning, indigestion, abdominal pain, diarrhea and vomiting. In severe cases, they can lead to liver failure and death.
