Some birds have learned to seek the security of a cage at night. Inside the aviary, provide a covered cage or similar retreat that these birds can enter and exit at will. Do not cut the birds' wing feathers. Instead, let them enjoy flying. Eliminate hazards like ceiling fans, pots of water, open toilet bowls, places where they could get stuck, sprayed vegetables, electrical wires, large glass windows and mirrors, etc.
Peanuts can contain aflatoxin, which is also fatal to birds.
Pencil lead can be fatal if eaten. Chocolate, avocados, and parsley are poisonous to birds. Make sure that none of your plants is poisonous to the species of bird living in your home. Food and Water Change the birds' water twice daily. Keep food and water containers above perches, high enough not to get soiled with droppings.
