In 1912, Dr. Leonard Cutler Sanford proposed a larger two-year expedition (that ended up taking five years) to South America for Rollo and Ida, and financed by Mr. F. F. Brewster. They traveled up into lakes and highlands of the Andes, along the coast, and out at sea to the Falkland Islands and Juan Fernández Islands, sailed around Cape Horn in a 12-ton cutter, and up into the Caribbean. This work and these collections proved invaluable to Robert Cushman Murphy, who later published The Oceanic Birds of South America based in part on the Brewster-Sanford Expedition collection of Rollo Beck.
