This is a report about birds in general Very good!
Birds are some of the most amazing animals on earth. Most have the ability to fly.
Some use ground travel. Some use claws, others use only their beaks. Birds come in many
varieties of colors and sizes.
Birds are warm-blooded, egg-laying creatures from the aves class. Along with the
obvious feathers and wings, birds have other adaptations for flying such as a wide keel on
the sternum, with large wing muscles attached, air spaces and sacs throughout the body
and bones, to decrease their weight, and they have various bone fusions and reductions to
strengthen and streamline their body.
