Its food consists of the smaller crustaceans, worms, snails, insects and their larvae. These are captured from the surface of the water, on the shore or are probed for, with the long, sensitive bills, in the soft soil of the banks or under shallow water. When feeding it moves in an easy and graceful manner. Its grace and dignity well merit the saying that "it is one of the most beautiful of the birds sought by the sportsman."

Neltje Blanchan has very aptly described the habits of this bird. She says: "It is not the intention of the Godwit to give anyone a near view of either plumage or bill. The most stealthy intruder on its domains — salt or fresh water shores, marshes or prairie lands — startles it to wing; its loud, whistled notes sound the alarm to other martins hidden among the tall sedges, and the entire flock flies off at an easy, steady pace, not rapid, yet not to be overtaken afoot. A beautiful posture, common to the plovers, curlews, terns and some other birds, is struck just as they alight. Raising the tips of the wings till they meet high above the back, the martins suggest the favorite attitude of angels shown by the early Italian painters."
