Though I'm not an expert on bird flocks and geographic loyalty, it has always seemed to me that the gigantic flocks of blackbirds move about from year to year. They may roost in the same location for several years, and then for whatever reason, abandon that place for another. It may have to do with availability of foods (large cultivated grain fields post harvest are favorite feeding areas), which are also ephemeral. You are certainly right about our care for the planet.
