I realize now that I neglected to include two other small projects coming next year: The Blunt-nose Leopard Lizard Conservation Center at Fresno Chaffee Zoo and the Kiwi Exhibit at Zoo Miami.
Thank you everyone for providing additional exhibits planned for the coming years, it can be tricky tracking down small developments in less-covered collections. I do ask that we focus on actual animal exhibits however; new hospitals and research centers are great, but those don't exactly classify as "exhibits" for the purpose of this thread.
