I know it looks like there is no more hummingbird nectar in the feeder, but there is some at the bottom. It's really hard to refill and I make my own nectar, so I only do it when it's completely empty. Plus hummingbirds LOVE snacking on all of our other flowers — zinnias, honeysuckle and more. I love seeing them. Maybe I can capture a photo of a ruby-throated hummingbird sometime? Apparently its the most common type of hummingbird in the eastern half of North America, so it might not be as hard as I think.
