Dear student,
The following are a few of the characters of the class Aves:
Animals of class Aves have a spindle-shaped body and the forearms are modified into wings. 
Their bones have air cavities (to make them light-weighted). 
They are homeothermic (warm-blooded animals). 
They have a four-chambered heart (two atria and two ventricles).
They lay eggs.
They breathe through the lungs.
