I see passing reference in that cite to "now we know Altamont is unusual",
and the a "#12" link, which doesn't seem to work for me.

Is it incorrect to shut down the Altamont Pass turbines?  I know there are
several different generations of turbine there, and some are now
decommissioned permanently due to bird strikes.

One thing I did get out of reading the 200 page report
was that the larger windmills turn slower and never
have any bird kills. The conclusion was to make all
wind trubines larger to alleviate this problem.

Altamont is unusual",

turbines?  I know there are

some are now

Altamont is a unique situation. A wind farm was located smack dab in the
middle of a migratory path. It would have been the same problem if it
had been cell towers. Other wind farms have less bird kills than a radio
tower cluster.

 Thanx. Here is the quote involving, how many hundreds
or thousands of windmills?

"After dozens of studies spanning nearly two decades,
we now know that the Altamont Pass situation is unusual
in the U.S. The high raptor mortality there was the
result of a convergence of factors, some of which were
due to the bad siting in the local ecosystem while
others were due to the wind turbine and tower
technology used at the time. In fact, a very different
situation exists not far away at the San Gorgonio Pass
Wind Farms near Palm Springs. A 1986 study found that
69 million birds flew though the San Gorgonio Pass
during the Spring and Fall migrations. During both
migrating seasons, only 38 dead birds were found during
that typical year, representing only 0.00006% of the
migrating population. "






scenario" and quite unique for

of birds that happens to

what... every second?

don't line up, and anyone


in perspective:

Two or three, actually, in the turbines I know - but that's _really_ slow

None.  I've never known a bird that's incapable of dodging a slow moving

I like Flare's cite from San Gorgonio - 38 dead out of 69 million (I hope
they didn't actually make someone count all 69 million).  That many birds
probably die from sheer exhaustion, or even just old age.
