Most bird species migrate some with the seasons, but this migration pattern comes in different flavors.  Consulting various authorities, I have identified eight flavors (variations), with the first being that many of the bird species that nest in our area just go south in the fall. I deal here with the seven other variations within which at least a few members of certain species overwinter in eastern KS. I gathered a list of ninety-plus bird species for which at least a few of each spend the winter with us. Not all of these species are mentioned here.
