The Hummingbird feeders were empty. I’m in the process of making a double batch of nectar. Since the twelfth, I’ve filled feeders a couple of times!! Perhaps too few flowering plants for Hummingbirds to feed upon? In Livingston, Texas (and North Carolina), I had flowering plants specifically for Hummingbirds, butterflies, and bees. The rose bushes in my yard (Waco) obviously do not provide nectar.
