Bat Fatalities at Wind Turbines

The general impact of wind turbines on the environment is likely far less than that of conventional power sources. However, recent evidence shows that certain species of bats are particularly susceptible to mortality from wind turbines. Bats are beneficial consumers of harmful insect pests, and migratory species of bats cross international and interstate boundaries. Dead […]

Bat deaths mount near wind farms

At a wind farm in Alberta, researchers noticed a disturbing trend – the turbines harvesting the wind sweeping across the Canadian prairie were also killing hundreds of migratory bats. Dead silver-haired and hoary bats piled up beneath the turbines. Necropsies indicated bleeding in the lungs. Since they were first reported in the late 1990s, bat deaths at […]

There’s a place for birds and wind

I am bothered by an ongoing controversy between bird lovers and energy developers that is taking place on the shores of Lake Erie near Port Clinton. As most people who have any connection to the outdoors surely know, that part of the Ohio north coast is an internationally known bird migration area. It takes in […]

Migratory Bats Hit Hardest By Turbines

Of Wyoming’s 15 resident bat species, three of them are most susceptible to the deadly effects of wind turbines: the hoary bat, the silver-haired bat and the eastern red bat. They are Wyoming’s only tree-roosting bats, said Douglas Keinath, senior zoologist with the Wyoming Natural Diversity Database. Because they roost in trees, they can’t protect […]

Hawk Watch at Mount Hood puts raptors in close view of visitors

The excitement of a sprung bow net quickly turned into a moment of deep chagrin this autumn at the raptor banding station near Mount Hood. “We just killed an adult male Cooper’s hawk,” said Dan Sherman  of Portland, a note of shock in his voice as he carried the body of the bird back into […]

Wind Turbines Endanger Frisky Bats

Tens of thousands of bats are killed by industrial wind turbines in North America each year. Three common species — hoary bats, red bats, and silver-haired bats — are estimated to constitute almost 89% of these deaths, and scientists are quite curious as to why. Since the vast majority of turbine-caused bat fatalities occur during […]

Master Naturalists: Hawk Watch 2012

Winter comes to the Great Plains and the Eastern U.S. Small birds run out of food – insects hibernate, seeds are scarce. As it has for eons, migration begins to warmer climes and food in Central and South America. With and behind the small birds come their predators: raptors. Raptors include hawks, eagles, falcons, kites, […]
