By the Numbers 
What does it take to come home from New Guinea with images of all 39 species of birds-of-paradise? Summing it up in two numbers—18 expeditions and 8 years—tells only part of the story. Numbers like 544 days, 109 blinds, and 39,568 photos give a little more perspective. Take a look at more numbers from the project to sense some of the energy and dedication that were required behind the scenes.
