Van, Cowbird eggs do look quite similar to cardinal eggs, and both have a fair bit of variability in the markings. Cowbird eggs are usually a little smaller; this difference, however, is slight.

So far, there are 2 eggs. Both eggs look remarkably similar to a cowbird egg that we confiscated from a prothonotary warbler nest earlier in the season. Short of DNA profiling, is there any way to tell the eggs of the two species apart?
