Species make up your life list, your year list and your field guides, but they are also key units of evolution and units of conservation and scientists do not always agree on what is and what is not a species (and sometimes they even flip flop).  John Bates, Associate Curator of Birds at the Field Museum will discuss the issues, challenges and value of defining species (or not) with examples from around the world.
