According to the American Bird Conservancy, the best estimates of the number of birds killed by wind turbines in the U.S. each year are based on three significant studies published in 2013 and 2014. Because each study was unique in its methods, estimated results vary from an average of 234,000 to 573,000 bird deaths per year. These bird deaths are caused by collisions with wind turbines and other structures such as power lines as well as by the disturbance and displacement of birds when wind facilities are built.

Broadcom MASTERS and Society for Science announce the top 30 finalists in the 11th annual Broadcom MASTERS

The top 300 Broadcom MASTERS are an interesting and diverse group of young people who not only excel in science, technology, engineering and math, but they also participate in a wide array of other activities. While it might not be surprising that 76 MASTERS are involved in science club, 129 participate in their local science or math Olympiad and 136 say they are involved in robotics, it is exciting to learn that nearly a third (96) are involved in student council, 65 participate in an art club and 36 are involved in a school publication.
