Hummingbird cake, that's a new one on me too. How many hummingbirds does it take to make one? Is it the entire hummingbird, or just its eggs?
A hummingbird surprised me once. I was on an outside balcony at work, 9 floors above street level. There were some flower planters near the railing. A hummingbird came straight up about 2 feet away from my face and went after the flowers in the planter. It was a fascinating 20 seconds.
