Jerry and I were so tickled a bit ago when we saw two hummingbirds at our feeder. I commented that one was much smaller and Jerry commented they were sharing. Then the larger bird flew over and fed sugar water down the throat of the little one! She did it several times and the little practiced drinking on her own as well. Then they flew away. I wonder if this is the pair I saw the other day, and the parent was teaching the little guy aerial stunts and advanced flying?
