The Fat Bird Week Contest celebrates Wisconsin’s native bird species and also aims to educate the public on ways to help them, said Emma Schatz, the digital communications coordinator at the Natural Resources Foundation of Wisconsin. “We thought Fat Bird Week could be a fun way to engage the community in a light-hearted thing, but then also incorporate that educational piece of learning the different ways to help protect Wisconsin’s birds,” Schatz said. In 2024 the foundation partnered with SOS Save Our Songbirds, a conservation organization that aims to protect birds, and started Fat Bird Week.
