Spots of two shades in a ring about large end.

June 26. 

C. has found a wood pewee’s nest on a horizontal limb of a small swamp white oak, ten feet high, with three fresh eggs, cream-colored with spots of two shades in a ring about large end. Have nest and an egg.

H. D. Thoreau, Journal, June 26, 1855

Spots of two shades in a ring....  Modern field guides say,  "3 [eggs], sometimes 2, rarely 4. Whitish, with brown and lavender blotches often concentrated toward larger end" (Audubon) and "White or creamy with a wreath of brown or purple speckles." (Cornell.)
