Terry,

There are two answers to this question;

(a) The oldest known Grey Butcherbird recorded from banding and
recovery is 18 years 9 months.

(b) The average life expectancy of butcherbirds is probably about1.5 -
2 years with an annual mortality of between 40-50%.

 Generaly the larger the bird to greater the longevity.

Does anyone know the life span of Butcherbirds?

I have a request for information from a luddite friend.  The story
behind
the request is the stuff that inspires people to write magazine
articles, if
not books.  Will fill anyone in who likes to reply directly.
