We just had a hummingbird in our house! It flew in through an open door. I had been cleaning my back patio and left the screen open for a few moments when I was putting stuff away.
The hummer flew upstairs and into our bedroom. After I discovered where it was, I closed the doors to all the other rooms and tried to shoo it out with a broom. Trying to "herd" a hummer is worse than trying to "herd" cats or teenagers!
I finally had to wait for it to get so tired it passed out grasping a screen on a window. I thought it was dead. It's tiny little claws were still clinging to the screen. Gently as possible, I pried them loose from the screen.
I picked it up, cupping it in both hands, and took it outside. Although it was still warm, it didn't move at all in my hands. But when I opened my hands it flew away!!!
It was quite an experience to hold a hummingbird in my hands, if even for only a few seconds.
