At BYU he was an instructor from 1926 to 1929.
In 1929 Cottam became a junior biologist with the U.S. Division of Biological Survey in Washington, D.C. In 1934 the Division of Biological Survey was reorganized as the Bureau of Biological Survey. Jay Norwood "Ding" Darling, the bureau's director, gave Cottam much of the responsibility for duck hunting regulations. During the early years of his federal government career, he was also a part-time student at George Washington University, where he graduated in 1936 with a Ph.D. In 1939, the Bureau of Biological Survey was removed from the U. S. Department of Agriculture and assigned to the U. S. Department of the Interior. In 1940, the Bureau of Biological Survey and the Bureau of Fisheries were combined to form the U. S. Department of the Interior's Fish and Wildlife Service. In the Fish and Wildlife Service, Cottam was from 1940 to 1942 a senior biologist in charge of food habits and from 1942 to 1944 was in charge of economic wildlife investigations in the Division of Wildlife Research.

He provided her with valuable documentation on existing DDT research. In her 1962 book Silent Spring, she cited his investigations of the harmful effects of insecticides.
For the academic year 1954–1955 Cottam returned to BYU as a professor of biology and dean of the College of Biological and Agricultural Sciences and then went on leave of absence from 1955 to 1958, when he resigned from BYU.
