Introduction
Between 1899 and 2024, Audubon (dating back to its beginnings as Bird-Lore) published more than 730 issues—and we catalogued the covers of nearly all of them. Birds, of course, featured prominently. We counted at least 243 identifiable avian species, with bird subjects appearing a total of 487 times. The magazine also showcased plenty of other wildlife and their habitats: Mammals graced our cover 79 times (representing at least 46 different species); fish, insects, and other animals, 25 times; specific plants, more than 50 times, and landscapes, more than 70 times.
Here, we illustrate these data in two ways—on the left, how broad categories of wildlife and their environments showed up over time, and on the right, the how those categories break down into species (circle size represents frequency).
