I've added a few fall yardbirds the past week: Northern Flicker, Common Grackle, Killdeer, etc., but no fall migrants yet. I am luring in the BCCH flock daily to make sure nothing is lurking quietly in the canopy.
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.
