The Wandering Tattler (Heteroscelus incanus) or 'Ulili was a common winter visitor in Kaelepulu Pond. It arrives in Hawaii in August and leaves for Alaska's breeding grounds in April. In the winter, it is dark gray above and light gray below. Its bill is long, thin, and black and its legs are yellowish. In breeding, its under parts are finely bare or striped with dark gray.

It also gives a single call note when startled. Tattlers are generally solitary, but are sometimes found in pairs or small flocks. Its diet consists of mollusks and invertebrates. They find their food by probing or searching in mud and under rocks. While hunting, they usually bob their tails. In Hawaii, tattlers inhabit mud flats, sandy beaches, rocky coastline, and streams.
