Are all male ostriches black and white or is there a species of ostrich that male and females look alike?

Male ostriches are typically black and white, while females are usually a more muted brown color. However, there is only one species of ostrich, the common ostrich (Struthio camelus), which exhibits this sexual dimorphism. All male ostriches of this species have the distinctive black and white plumage, while females do not resemble males in coloration. Thus, there is no species of ostrich where males and females look alike in the same way.
