I have noticed this about hummingbirds as well. We have a feeder on our deck and if you are out there when they are feeding expect to receive an inspection. I like to think the thought in their brain is “are you a flower?”

I’ve also had a hummingbird come within a few centimeters of landing on my hand while mounting biking (stopped, of course). I credit my new-at-the-time bright red gloves for that interaction.
