Thankyou
One for the FAQ, Stephen?
Earlier answers from Chris Mead:
> CAN ANYONE TELL ME HOW LONG A BLACKBIRD LIVES IN TH UK
Most dies very young. Indeed the average age of a newlky hatched
Blackbuird at death may be about two months. Some do live several
years and about one in a thousand gets to about eight years.
On Great Tits:
One adult will survive to breed next year and one of the chicks - on
average.
The concept of average age makes little sense with birds as they die
off rapidly from the egg. We tend to die off much later so average
age in Humans is a worthwhile concept. With Stalings I would expect
7-% of fledglings to die before the next breeding season. Half (or
slightly less) of the remainder to die ub the bext year and so on.
This means a three year old will not be too rare. a five year old a
bit unusual and a ten year old VERY exceptional. Oldest ringed bird
is 20 (I am not so sure I believe it but it is not far out).

Yes, it does seem to come up fairly often, doesn't it? I've added it to
the list of things to tackle sometime.

This is because the extremely fast heart rate - which gives rise to
their fidgity, eratic movements and flight. During the 18 months,
their hearts beat the same number as a 70 year old human's.
So in bird years, they are comprable to us.
