Parakeets need a varied but balanced diet and plenty of water. Dehydration can kill your bird quickly, so always make sure there's water in her cage. Instead of buying a standard bird seed, look for a seed mix that is designed specifically for parakeets. These often contain dried fruit and other nutrition your bird needs, such as calcium -- low blood calcium can cause sudden death. Give her some small pieces of fresh, raw fruits and vegetables to help round out her diet. Don't leave fruit in her cage all the time, though.
One reason is because most birds donât die from old age, theyâre killed and eaten by predators such as other birds and other animals, especially cats. Another reason is that birds migrate, and many die along the way and end up in rivers, lakes, and oceans.Of course, some ex-birds do end up on your lawn.If you find one before the neighborhood predator does, donât touch it with your bare hands. Birds, even dead ones, often carry viruses and bacteria that can make people sick. To deal with a dead bird, wear plastic or some other type of protective gloves to touch the bird.iven that birds migrate, itâs difficult to come up with an exact number for any one location, but itâs safe to say that the number of birds in the United States numbers in the billions. Although some birds have long lives, most birds that you see, like sparrows and finches, live only a few years.
