Why Stay? If they have a good supply of food, there's no reason—no matter the temperature—for robins to go anywhere until their food is gone. Robins that don't migrate as far gain advantages. They don't use energy in long migratory flights. They're better placed to claim the best territories for spring nesting. That's why some stay!
