In 1917, R. Bruce Horsfall, a nationally recognized naturalist and bird artist with ties to the Oregon Audubon Society, painted a magnificent series of 33 water colors depicting Western Bluebirds. These dramatic and charming works of art, along with the story text by his wife, Carra E. Horsfall, and the original pen and ink drawings have lain forgotten for more than a half century. In the course of a recent cleaaning at Portland's Audubon House, the drawings, text and paintings came to light.
