While not technically a food, alcohol is a poisonous food for parrots. Beer, wine and other alcoholic beverages depress a parrots organ systems, just like it does ours. However,m alcohol can be fatal to birds. Make sure that your bird stays safe by not allowing him to drink alcohol. Even a little sip to quiet him down! Some birds enjoy a walking onto the table and taking a nip, but alcohol and bird health don't mix!
2. Apple SeedsMany fruit seeds contain trace amounts of Cyanide. Not just apples, but peaches, cherries, apricots and pears have toxic seeds. While the fruit pulp is safe for your bird, the seeds need to be avoided. On top of poisonous seeds,fruit peel may have been sprayed with pesticides. Thoroughly wash and core all fruit that you share with your bird to avoid exposure to toxins.
3. AvocadoAlthough there is some debate regarding how toxic avocados are for parrots, it is generally advised to abide by a "better safe than sorry" attitude toward them. Don't allow your parrot to consume guacamole or other avocado products. Avocado skin and pits are suspected of causing cardiac distress and eventual heart failure in pet bird and parrots.
4. CaffeineCaffeine is known to be toxic to parrots so don't allow your parrot to consume any caffeinated beverages including soda, coffee, and tea. We had a Caique named Rascal for a number of years who would sneak swigs of coffee between scrambled eggs. It made him act like a maniac. We simply had to make sure he was caged as we drank our morning coffee. Caffeine causes cardiac malfunction in birds, and is associated with increased heartbeat, arrhythmia, hyperactivity, and cardiac arrest. What affects us with a boost in energy is potentially deadly to our pet parrots.
6. Dried Beans
While cooked beans are a healthy supplement to your daily bird food, raw, dry bean mixes are poisonous foods for parrots. Uncooked beans contain a poison called hemaglutin which is very toxic to birds. To avoid poisoning, make sure to thoroughly cook any beans that you feed your bird.
Mushrooms are a type of fungus that not only may result in digestive upset for our pet birds and may even induce liver failure.
10. Vegetable LeavesThe stems, leaves and vines of common garden plants such as tomatoes, potatoes and some other vegetables are poisonous to birds. Make sure that you only feed your parrot the actual fruit or vegetable part of garden plants and never the stems, leaves or vines.
