Wind Turbine Blade
This photo shows one of the three 135-ft blades of a turbine before installation. Although the blades of wind turbines appear to move quite slowly to the human eye, blade tips often move at speeds faster than 100 mph. ...

Hoary Bat
A hoary bat (Lasiurus cinereus) roosting on the branch of a tree. About half of all bat fatalities documented in North America involve hoary bats, a migratory species that roosts in the foliage of trees....
Location: USA
Hoary Bat Victim
A hoary bat (Lasiurus cinereus) found dead beneath a wind turbine, an apparent victim of a blade strike or near-contact barotrauma (lung failure from severe and abrupt pressure change; here, caused by the spinning blades). Prior to the problem of bat fatalities at wind turbines, biologists rarely en...
Location: USA
Bats and Wind Energy
USGS biologist Paul Cryan examines the carcass of a hoary bat (Lasiurus cinereus) found beneath a wind turbine. By examining the casualties, biologists hope to learn more about why migratory bats are so susceptible to wind turbines. ...

Bats and Wind Energy
USGS biologist Paul Cryan. Biologists hope to learn more about the scale and causes of bat fatalities at wind turbines by searching for carcasses of bats beneath turbines and carefully documenting the conditions under which they are found....
Location: USA
Wind Turbine
The species of bats that are most susceptible to wind turbines all roost in trees throughout the year, leading some scientists to speculate that they may be visually mistaking wind turbines for trees in which to roost....
Location: USA
Wind Turbines
Some of the larger wind energy facilities in North America are composed of hundreds of wind turbines dispersed across tens of thousands of acres, like this one in Colorado. ...

Climate Map for Northern African Python: Areas Potentially Suitable for Invasion
The Northern African Python ( Python sebae ) occurs naturally in a diverse collection of localities in central Africa. The climate-matched portions of the U.S. include peninsular Florida, extreme south Texas, Puerto Rico (right inset), Hawaii (left inset), and the other island territories (not show...

Implanting a Radio Transmitter in a Burmese Python
Researchers implant a radio transmitter in a 16-foot, 155-pound female Burmese python (Python molurus) at the South Florida Research Center, Everglades National Park. Radio-tracking builds understanding of where pythons spend their time and therefore where they can be controlled in practice. Photo c...

Black-Tailed Prairie Dog
Black-tailed prairie dogs are quite susceptible to sylvatic plague, but a new plague vaccine put in their food shows significant promise in the laboratory. The prairie dogs transmit the disease to endangered black-footed ferrets, who eat the prairie dogs and are also quite susceptible to the disease...

Amakihi Honeycreeper
During the past decade populations of this honeycreeper have begun to rebound at lower elevations on most of the main Hawaiian Islands, in spite of high prevalence of infection with avian malaria. Natural selection for resistance to avian malaria is the leading explanation for this rebound and rece...
