Birding proves to be good for the American economy

Some years back I put up nest boxes in my woodlot for the cavity-nesting birds. White-breasted nuthatches readily took to the boxes for raising broods, and for roosting. 
As our planet makes its autumnal tilt, a whole host of songbirds and raptors head south for warmer climes. But the woods are not vacant. The nuthatches live here year-round sharing the pinyons with mountain chickadee and juniper titmouse.
