OK Dweebs. Just made my first entry into the spreadsheet and am up and running with 13 species for 2010. Best bird so far: Brown Creeper which came to the trees near the feeder with chickadees this afternoon (first in months, actually!). Big misses: Eastern Bluebird (seen in the subdivision this AM but not in my yard), Turkey (Dec 28), House Finch, House Sparrow.
If you're all OK with it I will invite Skye Haas to join us (Marquette, MI), who has an interesting yard with quite different diversity than us.
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.
