Siberian pipit Anthus japonicus

Slender and drab songbird of open country. Brownish above with heavy streaking below. Distinguished from similar-looking (unrelated) buntings by thin bill and lanky appearance with long legs. Walks on the ground with jerky motions and frequently bobs tail. Breeds in tundra, while in winter and during migration, found in cultivation, moist grassland, and wetlands. Flocks are often heard as they pass overhead or flush from a barren field; listen for sharp, high-pitched call notes and look for flashing white outer tail feathers.
