From today's Public Domain Review newsletter:
100 years ago today, the very last Carolina parakeet passed away in Cincinnati Zoo. The reasons for its extinction are complex and somewhat mysterious, though evidence points to human activity playing a significant role.
The following image of the Carolina Parakeet is from the Public Domain Review's online store for fine art prints. The image appears in Mark Catesby's Natural History of Carolina (1731).
