what can cause sudden death in bird
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.
