Here I have attempted to make a complete list of lagomorphs present in American and Canadian collections. Only information 2017 or newer was used. Domestic species are excluded. Information missing holders or species, as well as information on subspecies or populations is welcomed.
As you can see, lagomorphs aren't very popular in North American zoos. The most common species are Desert Cottontail (4 holders) and Eastern Cottontail (2 holders).
Desert Hare (1 holder)
Dallas World Aquarium
Snowshoe Hare (1 holder)
Cleveland Museum of Natural History
European Rabbit (1 holder)
Great Vancouver Zoo
Desert Cottontail (4 holders)
Buffalo Zoo

El Paso Zoo
Springs Preserve

Daurian Pika (1 holder)
