At the south end of the zoo, you’ll find South Pond, which features a Nature Boardwalk that introduces you to prairie and marsh plants, as well as migrational bird species and other local animals that can be found here year-round. The islands in the center host a rookery for the rare and endangered Black-crowned Night Heron, which you’ll see congregating in enormous nests built in the treetops. On the left of this photo is the gorgeous Cafe Brauer, where you can grab some food and take in the vista.
