Whether they’re opening for takeoff, spreading wide for a lazy soar or flapping to brake for landing, bird wings make flying ...

Understanding these genetic interactions is crucial for unraveling how morphological novelties like proto-feathers emerged ...

Although it’s not uncommon for birds to communicate with each other by flapping their wings to make a desired noise, this was a particularly fascinating discovery because the two subspecies are in the ...

These small feathers on top of birds’ wings lay flat during normal flight but flare up in turbulence during landing. By attaching flexible plastic strips – “covert flaps” – to the top of ...

Birds are vertebrate animals adapted for flight. Many can also run, jump, swim, and dive. Some, like penguins, have lost the ability to fly but retained their wings. Birds are found worldwide and ...
