I want to know the answer to the following question:
Other than orchids and birds, what else is housed in the Orchid House?
All the background I'm provided with is that "Some points of interest are the Tropical House, the Cactus House, the Canary House and the Orchid House, which hosts one of the world's biggest collection of orchids, and free-flying birds and butterflies.". Is that enough to answer the question?
Answer: yes
