Elephants are mammals, ostriches are Flightless Birds.
Mammals are warmblooded vertebrates that, with few exceptions, give birth to live young and feed them milk from mammary glands after birth. The exceptions are the monotremes (the platypus and two species of spiny anteaters) that, like the ostrich, lay eggs. However, an ostrich does not suckle its young.
