From the tropics to the tundra, birds display a seemingly unrivalled diversity of life histories and behaviors. Thanks to the efforts of amateurs and scientists we have an increasingly solid grasp on birds’ geographic distribution worldwide and can start to map out, better understand, and more effectively conserve this fascinating variation. Professor Jetz will illustrate examples of his group’s research on the multifaceted global diversity of birds and how they attempt to assess its threats in a rapidly changing world.
