Fonds reflects Gould's bird watching activities in the North Bay area over the course of nearly forty years. The fonds consists of records documenting his daily birding observations from 1941 to 1979, with some interruptions in 1954-1957. Records include monthly reports of sightings, annual statistics, bird and mammal species occurrence records, and lists of species sighted. The majority of Gould's observations were made in "a rectangle which extends roughly thirty miles east and west and twelve miles north and south of North Bay." Some of his usual observation places within this area included his home on McIntyre Street, Peninsula Road on Trout Lake, the shore of Lake Nipissing west of the Government Wharf, and Eloy's Farm. He also frequently carried out observations while on walks, drives, and boat rides in and around North Bay.
