My hummers are Dumb!

For the 3rd time, I have had a hummingbird in my garage all day long. He just flies around the top and can't find the big huge OPEN door. I even took the car out and left the door open each time I left today. He has had no food all day and has surely used all his reserve, but I can't get him out. I even went to try to buy a butterfly net, but I couldn't find one. I'm leaving the door open tonight and the car out hoping he will find his way out. The other two that did this eventually found their way out. I never saw them get out and it might have happened after they fell to the ground and saw their way out. I give up. I don't know what else to do.
