The American pipit (Anthus rubescens), or buff-bellied pipit, is a small songbird found on both sides of the northern Pacific. It was first described by Marmaduke Tunstall in his 1771 Ornithologia Britannica. It was formerly classified as a form of the water pipit. Like most other pipits, the buff-bellied pipit is an undistinguished-looking species which usually can be seen to run around on the ground. It has lightly streaked grey-brown upperparts and is diffusely streaked below on the buff breast and flanks.
