Birds in Space Traditional Cache

We wanted to create a fun cache, and place it where it would not be muggled. With this cache, you will have to make sure to bring your own pen(cil) as there is no room for one in the container. Cache has new coordinates after being replaced for a third time. Cache was being destroyed by the wind, and has been moved about 32m North of original home.

Riddle:

NASA was considering sending canaries into space to study them under zero gravity.  The project was scrapped when someone realized that in spite of having sufficient water supplies, they would die of dehydration within a few hours.  Why?

Answer:

Birds, unlike humans, need gravity to swallow.  Humans can swallow, even while hanging upside down.

This riddle left us wondering where birds would live if they lived in space.
