Mt. Tamalpais
This was the closest I’ve ever been to hummingbirds and the most I’ve ever seen in one place. I spent 5-10 minutes holding still, trying to get one to land on my finger but no luck. I could see their little tongues and had no idea how frequently they poop. Their poops are these tiny quick little squirts.
Try wearing bright colors. I had one get close while wearing a t-shirt with a big yellow smiley face on it
