I've been having problems the last few years with hummingbirds going into my shed and then never making it out. It is a pole shed that I have a clear ridgecap on, so once they get in past the overhead door, they go all the way to the top because it looks like it is open and then they get stuck up there until they die. We don't have feeders out anymore because of this and don't really have much for flowers around either. I did notice them going in to check out the emergency release handle on the overhead door, because it was red, so I spray painted it brown. Short of keeping the overhead door closed, is there anything I can do to deter them from going in? We probably get about 1/2 dozen over the course of the summer that get stuck in there.
