Not like this compares to the previous posts, but for what it's worth I had a Black-and-white Warbler (pic below) and 2 American Redstarts in the yard today. Oh, and I added Scarlet Tanager and Red-eyed Vireo to the fall list.
2013 and beyond
It's pretty simple: the most birds seen or heard from one's yard during 2013 will be the "winner". Want in? O.k....then do it despite that.
2013 promises to be a lot less mean but still a carbon-free birding competition, even if slightly less exciting than a MEGA x EPIC hybrid.
