Petinha-fulva Anthus rubescens

Slender and drab songbird of open country. Usually grayish above and streaked below, but some lack streaks in breeding season. Distinguished from similar-looking (unrelated) sparrows by thin bill and lanky appearance with long legs. Walks on the ground with jerky motions and frequently bobs tail. 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. Song, given from a perch or in flight, is an often impressively lengthy series of repetitive, high-pitched notes.
