Horned Lark

Eremophila alpetris - Common in large fields, at the shore, and in other open places. Recognize adults by the black breast mark and facial design; immature shows these marks less distinctly. In normal flight, low and slightly undulating, notice the black tail feathers. Feeds in winter in freshly manured fields. Song, weak, high pitched, is repeated many times (9-13/minute) in a single flight overhead. Winter call, faint tinkling notes.
