Male Australian Black Swans’ eyes are usually red in color, but their eyes will turn white during mating season. If your swans’ eyes are white, then it means that they are getting ready to mate/nest. The eye color will change back to their normal red/brownish red coloring after mating/nesting season. Since this eye color change usually occurs in the male swans, it is quite interesting if your female swan is also exhibiting this white coloration. The Regal Swan
