Professor Emeritus Roger Lederer specializes in biological sciences, teaching courses in ornithology and ecology for the past four decades. He has published more than twenty scientific publications and has six books he either wrote or coauthored.
The latest addition to his repertoire is his new book titled "Beaks, Bones & Bird Songs." Below are some facts Lederer wrote about.
