關於和尚的壽命

In a June 1995 article, Bird Talk magazine placed the Quaker Parakeet on its top ten list of the best talking birds. The Quaker is a very hardy bird. Quakers can live to be 25 to 30 years of age and perhaps even longer. There are several mutations in the Quaker, although they are not commonly available. The blue mutation has become more established in the US, and many blue Quakers are now being kept as treasured companions. Lutinos, pieds, albinos, cinnamons and cinnamon-blues are are still rare. 以上是友站Robort所發表 可知和尚是蠻會講話的(前十名) 可是書上不是說和尚只有15年壽命嗎?怎會有25年呢?
