Golden eagles can be killed by colliding with a number of human-made objects, including wind turbines. USGS research wildlife biologist Todd Katzner describes his studies of golden eagle flight. This research is being done to model flight behavior which might help managers understand how placement of wind turbines might pose significant risks to golden eagles.

Dust Cloud from the Sahara Desert Moving across the Atlantic Ocean
From the USGS:
You’d often be surprised at how interconnected our global ecosystems can be. Take dust, blowing in the wind. You may have heard that dust from the Sahara can reach the United States. Well, not only can it reach us, that dust might have implications for our coastal waters.
Research led by the University of Georgia, Florida State University, and USGS shows that nutrients like iron found in Saharan dust can, under certain circumstances, lead to rapid growth of bacteria species like Vibrio. Vibrio is the genus that includes Vibrio cholerae, the bacteria behind cholera, so you can see why this is an important research area.
To be clear, we did not look at whether or not there were dangerous levels of pathogenic Vibrios anywhere in our coastal waters. But the discovery that Saharan dust can affect Vibrio population levels in Atlantic Ocean waters does warrant further investigation.
