Adult males are uniformly slate gray in color. During breeding, their legs and cere, or base of the bill, can turn bright reddish orange.

Adult females are brown in color with varying amounts of white streaking. Their legs typically are yellowish in color throughout the year.

Juveniles look somewhat like females, but have more of a reddish tint to their color than do adults, and the streaking tends to be buffy in color, rather than white as is more common for adult females. Juveniles also have brown eyes.

In contrast to juveniles, both sexes have deep red eyes as an adult. Snail Kites also have a sharply hooked bill that is used to sever apple snails from their shells.
