I've had two similar experiences with birds.
One was a sparrow that I found on the floor of my workplace. I first thought it was a hummingbird but later was told it was a sparrow. I scooted it on a piece of thin cardboard and took to the desk of a coworker. Someone said that it must be cold laying on the desk so my coworker removed a beret that he was wearing and placed the birdie on it. I had to leave the area but later my coworker later told me that the bird recovered after he had fed it some birdseed that our company sold. It flew away well fed I presume. I never would have thought that it was starving.
The other was a bird that flew into my house because I had my screen door open. It was frantically trying to get out without realizing that the door to my bedroom was open. I turned the light out thinking that it would have been attracted to the light through my open door but it was still fluttering around. I then realized it must have been was afraid of my presence so I left my bedroom and it finally flew out through the door that it came in through. A good recommendation to those who experience the same would be not to use a broom but to leave the presence of an open door or maybe window preferably with sunlight.
