longevity of birds

["John Leonard" <>]

The other thing to remember about longevity is that with birds almost all 
individuals die in the first year, or few years of life. Once a bird has 
survived this period it has acquired all the skills it needs, and has every 
chance of living to the near the longest possible span for that species.
All the birds we see around, except for the period after breeding, are the 
old, smart ones.
Human societies used to be like that too!
