I put my hummingbird feeder up yesterday morning. Today, one of them already had lunch there and in the afternoon, two territorial males were fighting for the spot. This one’s having dinner, literally an arm’s length from our front step. They are not shy at all. One of them also hovers in front of my window and tries to see what’s happening on my screen (he’s probably planning to sneak in and check out some hummingbird porn!)
