Birds keep a layer of soft, fluffy down feathers to regulate body temperature

Birds keep a layer of soft, fluffy down feathers to regulate body temperature Feathers are a sleek, intricate evolutionary innovation that makes flight possible for birds, but in addition to their stiff, aerodynamic feathers used for flight, birds also keep a layer of soft, fluffy down feathers between their bodies and their outermost feathers to regulate body temperature. Using the Smithsonian s collection of 625,000 bird specimens, Sahas Barve, a Peter Buck Fellow at the Smithsonian s National Museum of Natural History, led a new study to examine feathers across 249 species of Himalayan songbirds, finding that birds living at higher elevations have more of the fluffy down the type of feathers humans stuff their jackets with than birds from lower elevations.

High-altitude birds evolved thicker jackets

High-altitude birds evolved thicker jackets By Victoria Gill image copyrightAditya Chavan A study of 250 species of Himalayan songbirds has revealed how their feathers evolved for higher altitudes. The birds in colder, more elevated environments had feathers with more fluffy down - providing them with thicker jackets . The insight reveals how feathers provide the tiniest birds with such efficient protection from extreme cold. It also provides clues about which species are most at risk from climate change, the scientists say. image copyrightVictoria Gill It was just zipping around catching bugs. Dr Barve s fingers went numb as he tried to take notes.

Higher elevation birds sport thicker down

A new study examines feathers across 249 species of Himalayan songbirds, finding that birds at higher elevations have more of fluffy down than lower elevation birds. Finding such a clear pattern across many species underscores how important feathers are to birds ability to adapt to their environments. Furthermore, finding that birds from colder environments tend to have more down may one day help predict which birds are vulnerable to climate change simply by studying feathers.
