Electrical cords are a year-round hazard for birds who are not properly supervised in the home and allowed to wander about freely on their own. Christmas tree bubbling light fluid contains methylene chloride which is a very toxic solvent which can cause irritation to eyes and mucous membranes. Your bird can get lost under piles of wrappings, get tangled in ribbons, and be stepped on or asphyxiate before anyone realizes. Parrots cannot excrete salt the way humans can, so highly salted treats such as chips and French fries should not be fed. Also avoid foods high in fat or sugar.
Parrots easily develop bad eating habits, so it is unwise to encourage unhealthy snacking.
