Good to know I won't be missing ALL of the 'common' species I still don't have for 2010 (BTBW, etc.). CORE is next, I suspect.
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.
