In 1877, he made a second trip West, again writing articles for periodicals on his experiences. 1879 found him visiting Colorado and writing on mining operations. That year he also began his work describing shellfisheries for a joint project of the United States Fish Commission and the United States Census Bureau. That project lasted until 1881. His reports treated modern fisheries, and also discussed shellfish utilization much earlier by Native Americans and early societies worldwide.
Ingersoll was an early advocate of protection of wildlife and natural habitats, and preferred field notes and photographs to taking specimens. These views he presented in popular lectures around 1888. From the 1890s to 1905, he updated guide books for Rand McNally. He took up residence in New York City in 1900. At that time he was writing a weekly column for a Montreal paper. Letters he received from readers indicated a need for material on bird identification, and he did a series of articles presenting a list of Canadian birds with descriptions. He did a similar list for Canadian snakes, which his daughter Helen helped write and illustrate. Helen also helped illustrate some of his books. He stopped writing the column in 1938, when he retired. Ernest Ingersoll was 94 years old when he died in a Brattleboro, Vermont, nursing home after a four-year illness.
He married Mary Schofield (1853-1920) in 1873. They had two children: Helen (b. 1874), and Geoffrey (b. 1889).
