Similar species Sprague's Pipit is similar but slightly lower with more complex or more arched notes. Also, Sprague's does not give a double note or multiple notes run together. Instead, excited birds will give a fast series of separate single notes.
Behavior Primarily a nocturnal migrant but engages in resumed migration. Flight calls are given primarily by birds in flight and only rarely by perched birds. Flight calls uncommonly heard from nocturnal migrants.
