Relative Detectability: Easy to detect by its song, but fairly difficult to confirm breeding.

Challenge: Determine if this species breeds more widely than shown within the Columbia Basin (Wasco, Sherman, Gilliam, northern Morrow Counties) and in northern Klamath, northern Lake, eastern Deschutes, southern Crook, and central Malheur Counties.
