Jaws are absent.

Paired fins are generally absent.

Early species had heavy bony scales and plates in their skin, but these are not present in living species.

In most cases the skeleton is cartilaginous.

Only birds have feathers. Feathers are made of keratin. Feathers are critical not only for flight but also for warmth and protection against the elements; and in many species, for males to attract mates.]]> 2019-03-12 17:19:54 UTC https://padlet.com/misoto/lcpt8lzo6nrs/wish/340535584 misoto https://padlet.com/misoto/lcpt8lzo6nrs/wish/340537860 All birds have wings, although not all birds fly. Nor are wings confined to Aves; bats are flying mammals and most insects have wings. Birds' bodies are beautifully designed for flight, with strong chest muscles and just enough curve to their wings to provide lift.

Birds do not have true teeth. Beaks have sharp ridges along the edges of their beaks. Birds grind their food into pieces small enough to swallow. The shape of a bird's beak indicates the bird's general diet. Meat-eaters like hawks and owls have sharp, hooked beaks for ripping and tearing. ]]> 2019-03-12 17:25:49 UTC https://padlet.com/misoto/lcpt8lzo6nrs/wish/340539112 misoto https://padlet.com/misoto/lcpt8lzo6nrs/wish/340540415 All birds lay eggs, some very colorful or covered with spots. Eggs are not unique to birds, of course, as fish, reptiles, amphibians and insects also lay eggs. A bird egg has a hard shell made mostly of calcium and a layer of hardened mucus. Inside the egg, the developing embryo receives nutrition from the yolk and the albumin, the egg white. ]]> 2019-03-12 17:28:05 UTC https://padlet.com/misoto/lcpt8lzo6nrs/wish/340540415 misoto https://padlet.com/misoto/lcpt8lzo6nrs/wish/340541133 Most birds have lightweight skeletons with hollow bones.
