Since
a bird problem first emerged at the Altamont Pass Wind Resource
Area in California, we have learned much about the impact of wind
turbines on birds.
Though it now appears that the problem in the Altamont is an anomaly,
the fact that birds can be impacted is an important consideration
in siting and operating wind power plants.
Research
at wind power sites across the United States is helping us
to understand the magnitude of the problem, and to recognize how
problems can be avoided.
Birds
avoid colliding with wind turbines in most instances. Certain
behaviors may increase birds' risk of collision.
Certain
topographic features may increase the chance of bird collisions.
Some
types of turbines
may present greater risk than others.
Night
migrating birds rarely collide with wind turbines, contrary
to some beliefs.
Low
bird mortality has been found at European wind power sites,
with the exception of some coastal sites frequented by migrants.
To
date, impacts on bird populations have not been demonstrated
at wind power sites.
What
kills birds?
The answer to that question will probably surprise you. Here
is a list of the gravest dangers birds face
every day.
