Why can’t ostriches fly?

Ostriches are the largest living birds in the world. They can grow to 10 feet in height, can weigh as much as 400 pounds and are a member of the ratite order of flightless birds. They are believed to have descended from flying birds that lost their adaptation for flight. Though too heavy to be lifted by their wings, ostriches have strong, powerful legs that make them adept runners capable of reaching speeds up to 40 mph.

Ostriches, by the way, don’t really bury their heads in the sand. Some believe this myth originated with the ostrich’s self-preservation technique of dropping to the ground and extending its neck to avoid being seen.

Relatives of the ostrich include emus and kiwis.
