The Environment in Focus
About This Show
The Environment in Focus, hosted by Tom Pelton, is a weekly perspective on the issues and people changing Maryland's natural world. There's a story behind every bend of the Chesapeake Bay's 11,684 miles of shoreline, in every abandoned coal mine in the Appalachian Mountains, in every exotic beetle menacing our forests and in every loophole snuck into pollution control laws in Annapolis.

Kevin Omland, a biology professor at the University of Maryland, Baltimore County, stands below a highway overpass towering above a wooded stream valley in the Patapsco Valley State Park, just southwest of Baltimore.He aims his binoculars up at a scraggly nest of sticks that ravens built in the steel beams beneath Interstate 195. “Give yourself a second and you can see three young,” Omland said. “They are hanging out there quite peacefully. Not flapping, maybe stretching a little bit.” “Wow!" I replied. "Three large, black, sinister looking dudes sitting up on their nest under the bridge -- kind of ominous."“Tom, you’re squinting incorrectly. Those are beautiful creatures,” Omland said. “They are going to have marvelous iridescent plumage in just a few days.”
