Owners of free-flying parrots cast their birds into flight at the Singapore Polo Club yesterday. The flight was delayed by about half an hour as eagles were spotted flying in the vicinity, and owners kept their birds cool by spraying water droplets on them. The gathering of 170 bird owners and 150 parrots also saw them achieve the feat of 64 free-flying parrots in flight at the same time, which will be entered into the Singapore Book Of Records. It takes anything from two months to two years to train a parrot to reliably and repeatedly free-fly and return to its handler. It also takes dedication and commitment - six to 10 hours a week at the minimum - to consistently fly the parrot for a good portion of its life expectancy of 30 to 70 years. There are an estimated 5,000 to 10,000 parrot owners in Singapore, of whom 100 or so practise the art of free flight.
