I love old science and nature magazines and books. Although some of the information in them is outdated, the illustrations are often better than those found in newer magazine. Among my collection of old books and magazines are several issues of Michigan Conservation from the 1950s and 60s. One of the best things about the old issues of Michigan Conservation are the cartoons by Oscar "Ozz" Warbach. Ozz was a trained biologist who used his cartoons to teach people about nature and wildlife. Among other positions, he worked as a "conservation illustrator" for the Michigan Department of Conservation from 1954 to 1977. The Michigan Department of Natural Resources still sells a book of Ozz's illustrations titled Mother Nature's Michigan.
This cartoon about feeding birds appeared in the January-February 1961 issue of Michigan Conservation.
