Regional Differences

The Hawaiian subspecies (knudseni), also known as the Aeo, has more black on the neck and less white around the eye than stilts in mainland North America (mexicanus). A subspecies in South America (melanurus), sometimes called the White-backed Stilt, has a white collar across the upper back.
