Filmed during the Brooklyn Museum's Peruvian Littoral Expedition, 1919-1920. Robert Cushman Murphy, who was then a curator of the Department of Natural Science at the Brooklyn Museum, led this expedition and narrates the film. The expedition went to study the guano-producing birds on several Peruvian islands, including the islands of Santa Rosa. Some of the footage in this film was purchased from the National Guano Administration of Peru.
