On today's Take Note, we'll talk with bird researcher and Pulitzer Prize nominated author Scott Weidensaul. The eastern Pennsylvania based writer was in town for BookFestPA and talked with WPSU’s Emily Reddy before his visit about his best-known book, Living on the Wind: Across the Hemisphere with Migratory Birds. Then WPSU's Patty Satalia will interview ClearWater Conservancy's Katie Ombalski and landowner Sally Rothwell about a stream restoration project on the Rothwell Farm in Centre County. Ombalski says the improvements impact water quality all the way to the Chesapeake Bay.
