Not only is this the calmest hummingbird I've ever seen, but the bravest as well.
For some reason it really takes a shine to the woman who shot this video. Via her YouTube page:
I watched this little guy flying around, and he sat on the feeder and to my surprise let me get close and then hold him. He stayed for a long time and I wasn't sure if he was scared so I was trying to encourage him to fly away. His friend hovered nearby and makes a few appearances in the video as well.
When she tried to FaceTime her friend her new buddy flew away.
