There were several types of ancient reptiles that flew. Most famously the pterosaurs such as pterodactyl (Pterodactylus) were the 1st vertibrates to evolve flight.
Also it is quite likely that some species of the Dromaeosauridae family of theropod dinosaurs flew. They were later to evolve into birds. Infact the simularity between Dromaeosauride species and birds have led some scientist to argue for reclassification to birds.
The types of wings adapted for gliding on thermal updrafts are known as high aspect ratio wings. These wings are long and narrow, allowing for efficient soaring by maximizing lift generation and minimizing drag.
Soaring & gliding flight involve little wing movement. Birds soar & glide with their wings extended.
long broad and rounded wings
Probably better for gliding than flying. Depends on how the birds flap their wings, how big they are and how big their wings are.
Flight is a phenomenon that has long been a part of the natural world. Birds fly not only by flapping their wings, but by gliding with their wings.
Some creatures can fly without wings by using other methods such as gliding, jet propulsion, or buoyancy.
Gliding animals have indeed evolved structures that slow their fall. Their wings act as a parachute slowing their fall to the ground.
Pterosaur
it would be considered a reptile
Bats because they have wings they flap to get going unlike gliding squirrels!
birds have hollow bones and wings; reptiles don't.
Owls have large wings to improve lift and help in gliding. Speed is a product of thrust or gravity (altitude change). Think evolution gave them large wings so they can glide efficiently to the prey without making noise by flapping their wings.
