this could be the end of the story. Snow
fell last night and this morning. Just after
noon I walked over and had to dig around in
ca 1½" of powder snow to find the eggs. No adult
was in sight. I covered the eggs and left them.
2 July
Perhaps I spoke prematurely; today
the snow was gone and the nest was incubating!
If they hatch - it will be impressive - although
the fact that the eggs were fresh will
increase their chance of surviving. today
they have to endure steady rain.
