The red berries which Darius Ecker noted the Crossbills were eating (see his earlier report), I believe, are Winterberries (Ilex verticillata) our native deciduous holly. A little after noon, four White -Wings appeared at the same place, i.e, the west end of the pines. Also, Red-Breasted Nuthatches and Pine Siskins were around during the morning. Thanks to all who alerted us to this Crossbill invasion. Ralph Wall Great Falls, Va. Jan 10th.
