Birding gets a digital upgrade
Starting in 1882 and continuing for almost a century, the United State’s Bird Migration Program collected two-by-five notecards from bird watchers around North America. Today, these long preserved cards ? did we mention that there were over six million of them? ? are being dusted off, in the hopes that they can tell us something about a bird of a different feather: climate change. Jessica Zelt, coordinator of the newly established North American Bird Phenology Program where she is in charge of digitizing the cards, joins the show to tell us more.
