This is actually a pretty amazing story about a baby hummingbird that these people found on a sidewalk. He couldn't fly, so they took him under their wing. At night, he would come home to their house for safety. During the day, he was in the backyard of the house near where they found him. About 4 days after they found him, he was being held in cupped hands when his mama came by to feed him. She had seen them around, I guess, because she just flew over, perched on the hand and then fed him. This happened a number of times, so they called a friend who was good with a video camera, and he came over to film some of the amazing goings-on.

There's a lot more to this story, but that's enough info to give you some context for the video they posted on YouTube. Here's the link:
