I love hummingbirds. They have not yet returned to my area. We usually put the feeders out on Mother's Day. The males come first to stake out their territory, then the females show up. I am sure they nest nearby but I have yet to see a nest. You took some great pictures. Do you also put up feeders for them?
I don't watch any on line nesting but I do enjoy watching it around my home. We usually have several Robin's nests and also Wrens.
