What am I a bird in a nest?!

I stayed in a giant nest 50 feet off the ground this week. Runnermom called it a Lookout. I was too freaked to even go up the first flight of stairs. Once I was carried up top to the nest I was fine though. But no way was I coming out the door to the catwalk around the outside! Its not that I'm scared of heights but what am I a bird or a runnerdog?!
