      When you consider the furvival of birds in the subarctic, you realize that birds survive much harsher conditions than in or around Anchorage.  In the interior of Alaska, from Fairbanks to the tree line in the north, there is very little daylight and very low temperatures. At the Arctic Circle the sun does not even climb above the horizon for a few days and at best, only a few minutes of dim daylight with the temperature often at -70° below or colder for long periods of time.  Now that leaves 23-1/2 hours for a Chickadee to cope with no food and severe cold.  If the wind is blowing also, you can imagine what the birds are going through.
       
      In addition to Chickadees, year round residents also include Redpolls, Gray Jays, Red Crossbills, Pine Grosbeaks, Ravens, Great Grey Owls, Boreal Owls, Great Horned Owls, Northern Hawk Owls, Ptarmigan and Grouse.
