The first half of the journal is labeled, “Journal,” and documents various field trips made during Wilbur Mayhew’s undergraduate and graduate studies at the University of California, Berkeley. The journal also records early trips made at the beginning of Mayhew’s career at the University of California, Riverside. Observations are focused primarily on Mallards which was the focus of his Thesis (Ph. D. in Zoology), “Spring rainfall in relation to mallard production, Sacramento Valley, California.” The second half of the volume dates from 1947-1953 and is labeled, “Mallard.” It includes field studies aimed at replicating John Earl’s Mallard 1948 study at Conaway Ranch, CA. Notes include humidity and temperature readings for nests. Notes also include incubation experiment data.
