I came home from a shopping excursion the other day to find a wild bird, which appeared to be a Grackle, flying around the inside of my house. She slammed into every window she could find in an attempt to escape. After several attempts to steer toward an open window, she finally flew out. I remember thinking that there were no obvious ways a bird could have gotten into our house, but weird things happen from time to time. I gave a sigh of relief and chalked it up as a sign of something to figure out later.
