Willow Flycatcher
Easy to detect by its song, but difficult to confirm nesting. Some of the early-season reports of apparent fledglings may actually be males feeding adult females - a courtship ritual characteristic of the species.

Challenge: Refine knowledge of nesting distribution in Wasco, Sherman, eastern Umatilla, Deschutes, southern Jackson, Klamath, northern Lake, eastern Harney, and western Malheur Counties.
