Alveus is a non profit sanctuary with a lot of good cameras that can be better for AI recognition (I think). While I think a Zoo stream would be good too i think it could be better to collab with an actually entity like Alveus and set up something there rather than going out into the public world with an AI Vtuber. Im okay with a Zoo stream I am just suggesting an alternative. It also limits the stream time to about 2 to 3 hours because its not that big. It can also be a lesson for chat. 
They can also ask Maya questions about each animal.

This is a very low on the list suggestion because you have to upgrade the vision AI to a point she can recognize specific animals.
