When you enter the Tropics Hall via the 'tree structure', you first come through a dark corridor where some old agricultural tools and machines are exhibited. Then, you enter this area, which holds the indoor housing for the block of aviaries I showed earlier in this gallery. The real 'greenhouse' part of the Tropics Hall is on the right. Above this area is the second level of the Tropics Hall, which houses a series of cages holding birds and small monkeys.
