Dead Bird

I am watching another old guy. I don't think he should attempt migration, but of course he will:eagerness:. He should stay with me and the free food and clean water. He could last beyond his time.

I don't know the stats, but they must be something like:
--100 birds are born in 2000.
--100 are born in 2001.
--etc
--etc

Many will die in Al Gore Windmills but as this is a theoretical post, lets just deal with the 100 each year who survive and die of old age.

At or near the life expectancy of the bird, on average, 100 will die each year of natural causes.

To that end if a few hundred migrate to my yard, many will never make the return trip. Finding an occasional dead bird is not cause for alarm. You seldom do as a dead bird is food for many critters.

The same paradigm can be applied to all living critters, including humans.
You live - you die.
