David Sibley is never one for much fanfare, so we find, tucked into an exchange on his new Facebook page, that he is currently revising the big guide for release some time in 2013. Terrific. While my big guide largely lives at home, my small Eastern is beginning to accumulate duct tape.
If you don't already follow it, his blog has lately been a treasure trove of tricky ID tips (I would bet some of this material is part of his revision). His post today follows up on yesterday's New York Times article on the Snow Owl "invasion."
