The Puaiohi or the Small Kauai Thrush is a rare thrush that is endemic to Kauai. Puaiohi are small, drab birds that have long, slender blackish yellow bills. They have pink feet, legs and some white thigh feathers. The adult birds are highly similar and are olive-brown on top, while the belly is light grey. A white eye ring around the eye is a major trade mark of the species, which distinguishes it from its larger cousin, the Kamao. The chicks are brown, with a pattern interchanging white from brown. The bills of the young are more yellow and the belly is more brown then grey. The Puaiohi is some what tubby, however is not as tubby as it larger relative that lives on Hawaii, the Omao. It songs sound like water gurgling.
