We had a mama hummingbird set up a nest in the bush two feet outside our office window. What fun it was to watch from the two tiny eggs, to the two little "plucked chicken" looking skins, to the two tiny beaks being fed, and best of all was watching the first one start spreading its wings. Once that started mama would come back with food but fly stationary in front of the nest as though to say "look kiddo, this is the way to fly." We were fascinated by the whole process!
