@Erythrogaster do you have any insight into the (sub)specific designation of red-billed hornbills in US zoos? I remember seeing a nominate at the Smithsonian National Zoo in 2012 but that's the only time I've seen one listed specifically.
Also, if the private Yellow-Casqued Hornbill you're referring to is the female kept at Emerald Forest, I was told it died last summer. They also keep Silvery-Cheeked.
Bronx keeps Von der Decken's and Southern Ground Hornbills, the latter off-exhibit.
