One of my favorite pastimes is watching birds in my yard. I love to sit by the window or in the porch swing to watch them. I have mostly blue jays, finches, sparrow, robins and doves. I notice the doves are always in pairs. Blue jays are loners while the finches and sparrows are always in a group and don't seem to be in pairs. The robins may arrive two to four at a time; usually not just one, but not in a bunch like the finches or sparrows. Once in a while there will be a redheaded woodpecker. There are so many different kinds of birds that come and feed, that sooner or later you will see one that is not familiar. A good bird book is a handy reference to have.
