The snow geese are starting to return to Middle Creek Wildlife Management Area in Pennsylvania.  Every winter, they head north to their breeding grounds, stopping at Middle Creek along the way.  Mid-February to mid-March is usually when they visit, but timing is dependent upon the amount of ice covering the water and the amount of snow on adjacent fields.  The geese feed in the fields during the day and roost on the water overnight, so ice and snow cover keeps the birds away.  I’m looking forward to a few visits to Middle Creek this year…it’s become an annual photography excursion for me.  This image is from last year on a day when there were over 100,000 snow geese at Middle Creek!
