Since I had a Song Sparrow raise two hatchings of cowbirds last year, I checked the Song Sparrow nest a few weeks ago for Cowbird eggs. I saw what looked like one "larger" egg and removed it. The Song Sparrow abandoned the nest. Therefore I took the nest out for a closer look and found 2 more Cowbird eggs along side the 3 Song Sparrow eggs. If anyone would like to see the pictures of the eggs to see how close the Cowbird egg looks like the Song Sparrow egg, please e-mail me & I will forward them to you.
