  • The golden eagle - a large, powerful bird - is at the center of an effort to balance environmental protection and energy in the western United States.
  • 2
  • Government policy protects golden eagles.
  • 3
  • But it also supports the building and growth of wind farms.
  • 4
  • Wind farms are groups of huge windmills that produce electricity from the wind.
  • 5
  • The problem is that windmills are often responsible for killing golden eagles.
  • 6
  • The center of the conflict is Wyoming, a state where many golden eagles live.
  • 7
  • It is also home to a lot of large wind farms.
  • 8
  • In April, a Florida-based power company pleaded guilty in federal court in Wyoming to criminal violations of wildlife protection laws.
  • 9
  • Its wind turbines killed more than 100 golden eagles in eight states.
  • 10
  • The case was the third conviction of a major wind company for killing eagles in 10 years.
  • 11
  • Federal officials have tried to cut wind turbine deaths while avoiding any slowdown in the growth of wind power.
  • 12
  • Some consider wind power to be a better choice than carbon-based fuels that release carbon gasses into the air.
  • 13
  • Fossil fuel reductions are a big piece of President Joe Biden's climate-related plans.
  • 14
  • Bryan Bedrosian is the conservation director at the Teton Raptor Center in Wilson, Wyoming.
  • 15
  • He said, "We have some of the best golden eagle populations in Wyoming, but it doesn't mean the population is not at risk."
  • 16
  • He added, "As we increase wind development across the U.S., that risk is increasing."
  • 17
  • Golden eagles do not reproduce until they are about five years old.
  • 18
  • They have one baby bird, or chick, every two years.
  • 19
  • As a result, adult eagle deaths have large effects on the population, Bedrosian said.
  • 20
  • There are about 40,000 golden eagles in the U.S.
  • 21
  • Scientists say deaths from collisions at wind farms could drive down golden eagle numbers.
  • 22
  • Despite the deaths, scientists like Bedrosian say more turbines are needed to fight climate change.
  • 23
  • The U.S. Geological Survey (USGS) says the number of wind turbines nationwide more than doubled over the past 10 years to almost 72,000.
  • 24
  • Wind development projects often overlap with golden eagle living areas in states including Wyoming, Montana, California, Washington and Oregon.
  • 25
  • USGS scientists said in a recent study that increased turbine-caused deaths could cut golden eagle populations almost in half over 10 years.
  • 26
  • That could happen if predicted growth in wind energy continues, the scientists warned.
  • 27
  • But, the lead writer of the study, Jay Diffendorfer, said no population-wide decreases have been seen in recent years.
  • 28
  • This suggests that some predictions might not be correct.
  • 29
  • Climate change is also a great threat to golden eagles.
  • 30
  • The National Audubon Society warns rising temperatures could reduce golden eagle breeding areas by more than 40 percent within about 80 years.
  • 31
  • The federal government estimates that illegal shootings are the biggest cause of golden eagle deaths, killing about 700 golden eagles each year.
  • 32
  • More than 600 die each year in crashes with cars, wind turbines and power lines.
  • 33
  • About 500 are electrocuted and more than 400 are poisoned.
  • 34
  • Federal wildlife officials are pushing wind companies to take part in a permitting program that lets companies kill eagles if the deaths are offset.
  • 35
  • Offset means to create an equal balance between things.
  • 36
  • Companies with permits could pay utility companies to replace power poles, so that lines are spaced far enough that eagles cannot be easily electrocuted.
  • 37
  • Every 11 poles that are changed means one less eagle death each year.
  • 38
  • Nationwide, 34 permits that were in place last year permitted companies to "take" 170 golden eagles.
  • 39
  • That means 170 birds could be killed by turbines or lost through effects on nests or living areas.
  • 40
  • For each loss, companies are responsible for ensuring at least one eagle death is avoided somewhere else.
  • 41
  • Using conservative estimates that method could even mean a gain of eagles over time, said Brian Millsap.
  • 42
  • Millsap heads the U.S. Fish and Wildlife Service's eagle program.
  • 43
  • He said: "This sounds crass but it's realistic. Eagles are going to be incidentally killed at wind farms...We've got to reduce other things that will allow wind energy development."
