SCIENCE STUDIO: Animal Behavior

In a rebroadcast from Aug. 30, 2009, Keith talks with Matthew Anderson from the Department of Psychology, St. Joseph's University, Philadelphia.  He talks about animal behavior, specifically that of flamingos.  Why do flamingos stand on one leg?  Do they prefer the left leg over the right one?  And why are flamingos pink?  Could they be another color?  Aired March 24, 2013.
