How Long Do Parakeets Live? Parakeets tend to live 10 to 14 years, if in good health. Not all will live that long, however, since parakeets can fall ill even with proper care. Improper care can shorten their lifespan to a mere 4 years or less. Consider these parakeet care tips.
Quick Answer. Parakeets, also known as budgerigars or budgies, can live up to 20 years, but 12 to 14 years is more likely. English parakeets and those that are kept in captivity tend to have shorter lifespans and may only live 5 to 8 years. Just like with any other animal, the lifespan depends on a variety of genetic and environmental factors.
