Regional Roundup: All About Birds

On the latest regional roundup, the annual Audubon Christmas Bird Count starts December 14, and around the region, groups of bird counters are participating in this important community science event. We'll have a few bird-related stories, plus an interview with the author of 'Killdozer,' which tells the story of Marvin Heemeyer, who in 2004 modified a bulldozer with concrete and steel and demolished numerous buildings in Granby, Colorado.
