An air-filled sac within the birds' lungs is believed to increase the force the birds use to power flight muscles while soaring. Soaring birds -- like osprey, eagles, falcons, even vultures -- can ...

Wind turbines may seem innocuous enough, but they have the potential to reshape the air birds fly through. In a recent Scientific Reports paper, researchers found that a gliding bird's lift-to-drag ...

While it had been assumed that unstable gliding was the key to agility in bird flight, a collaboration between aerospace engineers at the University of Michigan and biologists at the University of ...

California condors are increasingly being spotted above Zion National Park in southern Utah, drawing startled reactions from hikers who see the massive birds gliding along canyon walls. The species, ...

Engineers are finding new ways to make wind turbines more efficient by stealing design cues from one of the world’s heaviest aerial birds, the Andean condor. This is according to new research ...

Soaring birds — like osprey, eagles, falcons, even vultures — can stay aloft in the air seemingly forever, rarely flapping their wings. They glide along rising air currents in a way that has ...

While it had been assumed that unstable gliding was the key to agility in bird flight, a collaboration between aerospace engineers and biologists has revealed that stability plays a role. While it had ...
