When a bird isn’t flying, it folds its wings neatly and tucks them against its body, out of the way. What’s more, when the wings are closed, the feathers that are most important for flight are ...

You can know a lot of things about birds just by the shape of their wings. A seafaring albatross, stretching out its sail-like airfoils, lives a very different life from a ground-dwelling antpitta ...

"So what you get for a bird wing is an airfoil made up of airfoils, and the bird has muscle control over all of those feathers, so it can constantly adapt and change the position of feathers and ...

The vane on the leading edge — or “forward,” in the direction of a bird’s flight — is narrower and the fibers are generally ...

Rows of flaps inspired by bird wing feathers improve airfoil performance by boosting lift, reducing drag and mitigating stall. Skip to content. Subscribe or renew today ...

To study this observation, Wright and her team built a remote controlled plane with wing loading and airfoil characteristics similar to a bird, plus variable wing sweep. Preliminary results are ...

Check out this gorgeous "bird wing" filament eruption today. Thus far, it looks like it will mostly miss us, but we could get the wake of the structure passing by Earth sometime May 16." ...

Owl wings enlighten ... “Nocturnal owls produce about 18 decibels less noise than other birds at ... It is generated when airflow passes along the back of an airfoil, such as the wing or ...

The fixed wings of Gossamer Albatross are certainly too lightly constructed to be flapped -- they are also far too light to be safe. If flapping wings move too slowly there will be little gain.

Birds originated from a group of small, meat-eating theropod dinosaurs called maniraptorans sometime around 150 million years ago. Recent findings from around the world show that many ...

In comparison to modern birds, the prehistoric Archaeopteryx and bird-like dinosaurs before them had a more primitive version of a wing. The findings, reported on Nov. 21 in Current Biology, a ...
