Just now (11:18PM) had my yard lifer BBCU (also a life yearbird) and SWTH (ditto) fly over the house. BBCU was low and came through clearly. Good thing I listen with my window cracked so I can count these things- they don't often give you a second chane. Also had CONI at dusk over Whitefish Lake (life yardbird and yearbird). It's no WHIM, but I'll take it.
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.
