An update to my species list from 2019. Since that time two new exhibit areas have opened: a Black Rhino/mixed savanna complex and an Australian complex. Additionally, the Sonoran/Palm Oasis Aviary has been revamped; some of its inhabitants (egret and herons) were moved to the small walk-in aviary on the North American loop, while some of its new inhabitants (owls and raven) are from the carousel of small American aviaries. Seen species are in bold; each bullet is a separate enclosure unless otherwise noted.
