What type of birds build their nest on the ground?

There is a nest on the ground in my yard inbetween some fern leaves and it has 3 blue eggs in it. It was deffinately built there, it didn’t blow down from a tree, it is all intact. I live in NH if that helps. And before you tell me to leave it alone, I am not interested in disturbing it. I am just curious.

There are a number of ground-nesting birds in NH, from killdeer to gamebirds like pheasant, turkey, and quail, to the night birds like whip-poor-wills. But I know of none that lay blue eggs. Most are buff, brown, olive or white.

Also, ground-nesting birds do not construct nests the same way tree-nesting birds do. They just make a depression in the ground or lay the eggs among dead leaves.

If this is a nest, it had to come from a tree or shrub. Maybe it fell, and the mother repaired it and continued to use it on the ground? Robins would be the first bird I think of with blue eggs. Keep an eye on it and see what comes around that area. Maybe you’ll see a bird sitting on the eggs toward evening.
