Turns out the larger eggs are a match for wild turkey and the smaller ones a fairly good match for mallard. The finder of the eggs figured it out after I got only a few guesses from OBOL. Still a mystery is which bird first established the nest and which was attempting to parasitize.

Subject: Bird egg/nest mystery
Some volunteers at Rasor Park, a 10 acre city park that is being managed as a "nature park", found these bird eggs while clearing poison oak by hand. They immediately left the area and saw no adult birds. I went there today, a few days later, and again saw no adult birds. It appears that there are 2 nests side by side and the eggs look like they are from 2 different species, mixed in each nest. The larger eggs are about 3 1/8 inches long and the smaller ones 2 5/8 inches. The larger ones are cream-colored with brown speckles and the smaller ones have a blueish tinge. This park is on the Willamette River and the ducks/geese that have been recently seen in the park are mallard, gadwall and Canada goose. These eggs don't seem to fit descriptions and photographs for those species in my "Western Bird Nests" book or photos I've found online. Does anyone have any idea what bird or birds laid these eggs?
