I really love birds. Aviaries are the first enclosures that I visit when I go to zoos. I could spend an entire day sitting in an aviary, which is currently my volunteer retirement plan. I purposefully hike/walk in areas that attract birds. If I was a billionaire, I would open the world’s largest aviary, which is currently seated by Birds of Eden in South Africa. Other people in my family also love birds, so I think it must be genetic. 
I don’t think anyone on e4 could beat me in a bird spotting contest. But if they could, I would have a lot of fun losing to them.
