Habitat and Birds
This is the only known breeding location for Black Swifts in Oregon. They nest behind the falls and can be seen flying high over the bowl, below the falls, and sometimes high in the sky to the south and west of the viewpoint. Vaux’s Swifts also fly over the falls. This has also been a reliable area during the nesting season for Townsend’s and Hermit Warblers. One pair of Northern Waterthrush occasionally nests in the marshy area along Salt Creek just east of the falls along Highway 58. American Dipper can be found here, especially at the car bridge above the falls.
This is a US Forest Service fee area. Permits can be obtained in the parking lot.
