Somehow I have not yet observed a Swainson's Thrush in Michigan for 2009, yet my second Gray-cheeked of the year has already shown up in my yard. This species is normally outnumbered probably 10 to 1 by Swainson's here!
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.
