Budgie Diet
You need to check your pet budgie's cage every day to make sure he or she has plenty of food and water. Especially when the days are hot, change the water every day to keep it fresh. It is important to keep your budgie's diet, as a seed-only diet will not provide a certain kind of nutrition. At least every other day try to provide your budgie with a fruit or veggie to munch on. Don't leave fresh foods in the cage too long, perhaps a couple hours at the most. Budgie favorites include carrot tops, dark leafy greens, and strawberries. You will learn what your particular budgie has a preference for. Just make sure to keep his diet the same to keep your budgie's health and longevity healthy.
Vegetables and Fruits
As I was saying, budgies come from the wilderness so they hunted fruits and vegetables. Some budgies ate other things because not all budgies lived in the wilderness they lived in other places too. They lived in rainforests, woods and other hot places too. They ate lots of fruits and vegetables to make them better at flying and to have more talents at other things they need to do to survive. That was the time when people decided to catch these birds to have a better life with a mate they never met while being in their main home. That's when they forgot about fruits and vegetables and in their cages they ate diferent seeds and pellets.
