Size
6–8 in long (15–20 cm) — a slim, walking songbird (typical for the family)
Habitat
Open grasslands, prairie, pasture and hayfields.
Diet
Seeds and insects gathered from grasses and the ground.
Range
Recorded on 57 Breeding Bird Survey routes across 8 states, most concentrated in the Southern Rockies / Colorado Plateau.
Family
Motacillidae · Grassland birds

American Pipit Conservation Status

Our route-weighted index shows it up about 1901% since 1976. Grassland birds are North America's steepest-declining group, down roughly 50% since 1970 as prairie and pasture were lost.
