American robin

Lovely

Based on the color of the eggs, I would guess that they are Robin eggs. i found this info: Female robins choose the nest sites, which are typically on one or several horizontal branches hidden in or just below a layer of dense leaves. Nests are typically in the lower half of a tree, although they can be built as high as the treetop. American Robins also nest in gutters, eaves, on outdoor light fixtures, and other structures. In western prairies, American Robins may build their nests on the ground or in thickets, while in Alaska they sometimes nest on buildings or cliffs.

Could be a Robin. I found this (scroll for replies) http://prairieecologist.com/2012/05/02/ground-nesting-robins/ Though this is the case for areas with very little trees. Bluebirds and Starlings make there nests in cavities.
