I had a great run at Wildwood but something changed and it was harder to find things.  It may have been that I didn't need anymore bird photos or it was time to get off the road and do some exploring.  I had shot for two or so years, shot in the heat of summer and cold of winter.  The cold never bothered me.  Loved snow.  You dress for success and up till now gloves were worn but never for fondling the small dials and buttons on a camera.  I had to loose the gloves.   Numbness sets in fast.  A bigger problem  is all the white and getting exposure without losing details.  This is where manual settings excel, why you should learn to use your camera that way.  A lot of white or black will confuse the camera.  Snow isn't the only white.  Many of the birds are white and very dark in spots. When I was using auto ISO  I lost a lot of detail with Egrets and Eagles setting or in flight.  I recall being told set your camera for what you want to shoot and not worry about getting everything.  The example was shooting Eagles in flight when they are up in the air where it is bright and when they are going in catching fish on the darker water.  Shoot for the water or for the flight after.  Maybe a better example is shooting a Green Heron foraging along the bank and an Egret close by snatches up a frog and you turn quickly to shoot the white bird.   This is another 10,000 click issue.  I lost a lot of pictures that would have been great shots but I had a hot subject.  By now I am getting closer to the experience needed to make faster adjustments without thinking.  The fingers are a little more automatic.   They did it in the film days when they had to wait to see how the film turned out.   This photo is a good example of white and good exposure.  I always use the spot meter on my camera to get the white right. 

I generally shoot 1/2 or so stop hotter when shooting white to compensate for the camera wanting to see grey.  That's my camera yours may be different. And remember the light changes fast in early morning and late afternoon so you may need to constantly change that setting.
