Can a mustang (horse) be a female?

Mustangs are descendants of Spanish, or Iberian, horses that were brought to the Americas by Spanish explorers in the 16th century. The name was derived from the Spanish word mustengo, which means "ownerless beast" or "stray horse." Many people think that mustangs are simply wild horses rather than a specific breed... Like other mammals, mustangs have live births. Their babies are called foals. Mares carry their foal for an 11-month gestation period. Mustangs typically give birth to their foals in April, May, or early June, according to the American Mustang Handbook.
