Platte River Status: A rare migrant and summer resident, Rosche (1979) reported that one was mist-netted at the Cedar Point Biological Station, Keith County, on 9 August 1978.
Breeding Range: Apparently most numerous during the nesting season in the lower North Platte River Valley in Garden and Keith Counties; one record from Dawson County.
Breeding Population: The population in 1979-1980 was estimated at 70 breeding pairs.
Habitat: We found the highest mean nesting density in lowland forest (0.5 pairs/km2), and in river channel island (0.2 pairs/km2). Rising (1974) stated only that Contopus sp. flycatchers were local summer residents in woodlands of western Kansas. Stewart (1975) found that western wood-pewee in North Dakota was restricted largely to stands of cottonwood with partially open canopy along the floodplain of the Little Missouri River.
Effect of Habitat Alteration: Habitat alteration has probably not produced any impact on this species in the study area because of the small number of breeding individuals occurring here.
Nesting Data: We have no confirmed records of nests or eggs from the study area. Short (1961) suggested that hybridization between eastern and western wood-pewee may occur in western Nebraska. Egg dates from South Dakota range from 1-21 June (Johnsgard 1979).
