What age can humingbirds fly?

If a lovebird is three years old, it's in the first fifth of its lifespan. If a blue and gold macaw is 10 years old, it is in the prime of its life, with 70 more years to go if cared for properly. http://news.bbc.co.uk/1/hi/uk/3410893.stm Charlie, a blue macaw bought by Churchill two years before the outbreak of World War II, is now entertaining customers at a Surrey garden centre with obscene anti-Nazi tirades. His owner, Peter Oram, says he believes Charlie is 104, making him the oldest parrot on record.
