Wind Turbines Don't Make Birds Fly the Coop

A study finds that, despite concerns, offshore wind farms are largely not harmful to seashore or migrating birds. The presence of wind farms affected only one in twenty-three species. Although researchers warn not to extrapolate these results to inland birds, there seems to be little fear. The article mentions, in passing, that the wind farms are, however, dangerous to bats.

Researchers have developed a computer algorithm that can identify some plant species according to their unique sonar echoes. The experiments were meant to help biologists understand how bats find their favorite fruits or insects, but the research might also help engineers design high-speed systems to identify everything from widgets on conveyor belts to faces in crowds. 
Six New Prehistoric Bat Species Discovered in Egypt

The new species were found by experts who analyzed 33 fossils—including teeth and jawbones—that had been unearthed over a period of decades in El Faiyum, an oasis region 50 miles southwest of Cairo 
Bat's powerful lift is illuminated by fog

Bats have a clever aerodynamic trick to make flying easier, researchers have found: the sharp edge at the front of their wings cuts through the air in such a way as to create a vortex on top of the wing, producing up to 40% of the lift needed to stay aloft. 
Ancient bat flew without echolocation

Among those who study the evolution of bats, the question of whether the bats developed echolocation and then flight, flight and then echolocation or developed both traits in tandem is a matter of great debate. A discovery in Wyoming not long ago has tossed some more gas on that fire.
The 52.5-million-year-old bat unusually had a claw on all five digits of each limb, earning it the nickname "20-clawed bat." Its anatomy shows that it captured its prey without the use of echolocation. The echo-first campers have yet to respond.

Bats and birds use their wing-flapping powers differently, a video study of the night flyers reveals. Bats leave a more complicated pattern of swirling vortices in their wake, and work harder on their upstroke than birds. This, the researchers say, may be the secret to their super-maneuverability. And it means that they fly a bit like a bee.

Many people doubted that even a big flying mammal like Nyctalus lasiopterus could feed on birds. The feathers in the bat droppings ought to have been a clue.
