Reptilian scales and bird feathers are made of the same substance; keratin. Bird feathers evolved from degenerated dinosaurian (coelurosaurian?) scales. The feathers were probably first used for insulation or were perhaps used en massealong the arms to form 'traps' for catching insects.
''A small minority of researchers have claimed that the simple, filamentous "protofeather" structures are simply the result of the decomposition of collagen fiber under the dinosaurs' skin or in fins along their backs, and that species with unquestionable feathers, such as oviraptorosaurs and dromaeosaurus' are not dinosaurs at all, but true birds unrelated to dinosaurs. However, a majority of studies have concluded that feathered dinosaurs are in fact dinosaurs, and that the simpler filaments of unquestionable theropods do in fact represent simple feathers. Some researchers have demonstrated the presence of color-bearing melanin in the structures which would be expected in feathers but not collagen fibers. Others have demonstrated, using studies of modern bird decomposition, that even advanced feathers appear filamentous when subjected to the crushing forces experienced during fossilization, and that the supposed "protofeathers" may have been more complex than previously thought. Detailed examination of the "protofeathers" of sinosauropteryx prima showed that individual feathers consisted of a central quill (rachis) with thinner barbsbranching off from it, similar to but more primitive in structure than modern bird feathers.''

Penguins are birds. They have feathers and lay eggs.
The flight feathers are the feathers located on the wings and tail. There are primary flight feathers that on the bird would be equivalent to our hand. A bird also has secondary flight feathers which when comparing to a human would be our forearm. If you unfold the wing of a bird you will see the flight feathers.
The birds feathers are used for, insulation , this is for when they fly and when thier on the ground, it also helps pretect the skin, from getting damaged.
Birds do not have hands or paws on their wings. Contour feathers along the wing are called flight feathers, and are specialized for lifting and gliding. Feathers are a strong and adjustable surface for pushing against air.
All birds have feathers and birds are the only animals that do!
As with other birds, the wing of a blue jay is covered in feathers.
No. Only birds have feathers. Kangaroos are mammals, not birds.
Yes. Kingfishers are birds, and all birds have feathers.
Pretty much all birds have feathers
no they have feathers
There are no animals that have feathers besides birds.
Cassowaries are birds so, like all birds, they have feathers. Only mammals have fur.
Mammals are not covered with feathers. Mammals grow hair, but do not have to be covered with hair. Birds are covered with feathers.
NO!! because they have feathers
Yes, especially because they are birds. :)
Cute question! Birds like to get high. Feathers allow birds to fly.
