What are the characteristics and functions of an ostrich's wings?

The ostrich is the largest and heaviest bird in the world. Because it is inconvenient for it to forage in the air, it has no choice but to stay on the ground, and over time its wings degenerated so that it can no longer fly. So what are the characteristics and functions of an ostrich's wings?

What are the characteristics and functions of an ostrich's wings

They are mainly used for balancing the body. In spring, when seeking a female ostrich, it spreads them and dances, and the superior one wins. When fighting an enemy, it opens and closes its wings to give itself courage.

Why can't an ostrich fly?

The reason an ostrich cannot fly is not a matter of wing size or muscle capability, but because it lacks the flight feathers, tail feathers and uropygial gland needed for flight.

The ostrich's body weight is too great, and it often forages and moves on the ground. Over a long period of time, its wings began to degenerate, and among its feathers there are no longer the flight feathers and tail feathers needed for flight, nor even the uropygial gland, the feather-maintenance organ——this is the thing used to secrete oil to protect the feathers from deforming. Some parts of flying birds do not grow feathers, which are what are called feather tracts and bare areas, but the ostrich's feathers grow evenly distributed over the entire body surface, with no distinction between feather tracts and bare areas, so wanting to fly is naturally out of the question.
