Introduction
In 2004, Cornell University Lab of Ornithology scientist Edwin Scholes and field biologist and National Geographic photographer Tim Laman set out to complete the first comprehensive study of all birds-of-paradise. After 8 years and 18 expeditions they have amassed photographic and video coverage of all 39 known species and documented several new behaviors. Found only in New Guinea and parts of Australia, the birds-of-paradise are a case study in the evolutionary power of sexual selection. Their fantastic plumes and bizarre courtship displays are a result of millions of years of sexual selection at work in an environment with plentiful food and no natural predators.
