Birds have quite a long life expectancy. A bird kept in a zoo lived up to 80 years old. This is longer when compared to how long some people live. In captivity, it is not unusual to find 20 or 30-year-old pet birds, perhaps even older. Generally, the larger the bird, its lifespan is usually longer. So, for instance, common pet cockatoos will have a longer life expectancy than sparrows. If you own a bird, you will likely want to maximize its lifespan as much as you can.
Unfortunately, the main problem of pet birds would be their diets. Bird owners unintentionally purchase unhealthy, low-priced food that will not offer every nutrient that is needed for the animal to prosper. Or, owners might also share some table scraps with their pets, adding up gradually over time. You may, on occasion, offer a bit of your quesadilla to your pet bid. And like humans, small treats and snacks compound over time, causing issues at a later time.
This is not saying that you must never offer your pet bird small portions of your food. Instead, your pet’s main diet must include fresh vegetables and fruits, as a human would too. Carrots and lettuce could be offered to your pet in addition to top-quality bird food. Offer treats sparingly.
A sudden change in your pet's appetite and/or eating habits should warrant a visit to your vet McHenry, IL.
