Horsfall was born in Clinton, Iowa, in 1869 to John Tomlin and Anne Buttersby Horsfall. He studied at the Cincinnati Art Academy and later at art schools in Munich and Paris. From 1904 to 1914, he did scientific illustrations for the Princeton Patagonian Report, and lived at Princeton University for most of that time. He married Carra Elisabeth Hunting in 1906 and had two sons (one adopted). The family moved to Oregon in 1914, where Horsfall was an instructor at Reed College. In 1923 he moved to New York, where he worked as an artist for Nature magazine. He died on March 24, 1948, in Long Branch, New Jersey.

Horsfall enjoyed painting wildlife, and contributed to a number of field guides, scientific publications, and conservationist works. He was a member of the American Ornithologists' Union, the Cooper Ornithological Club, the Northwest Bird and Mammal Society, the American Society of Mammalogists, and the American Museum of Natural History. Horsfall's paintings were first exhibited in Chicago in 1886, and later at the Chicago World's Fair in 1893. At the time of his death in 1948, there were permanent exhibitions of his work at the Peabody Museum of Natural History at Yale University, the Kent Scientific Museum in Grand Rapids, Michigan, and the Zoological Museum at the University of Minnesota. Two portraits he painted were also hung in Guyot Hall at Princeton University. In 2023, the Oregon Historical Society showcased 55 of Horsfall's watercolor bird paintings in the exhibition Birds of the Pacific Coast: The Illustrations of R. Bruce Horsfall.
