While I wish we had a greater variety of hummingbirds here in the Ozarks, the little Ruby Throats keep me amused and busy filling their feeders. For some reason they have been very active and in a feeding frenzy just before sunset for the past three evenings. Last night all four ports were occupied on the deck feeder, two hummers were waiting their turn and another was hovering at the glass door where I was standing. I though it said they needed another feeder.
