Anyone who thinks all the vertebrates of this world have been discovered and described should think again. This book chronicles the work of ornithologists in the mountains and jungles of Peru and elsewhere in South America as they hunt for new and often exotic bird species. Focusing mainly on the work of LSU ornithologists and in particular the accomplished John O'Neill, it provides a first hand view of such expeditions, describes many of the new birds species found, shows how ornithologists work (it's not just bird-watching either), and provides interesting discussions on issues relating to taxonomy, scientific credibility, collecting specimens, conservation, neotropical ecology, evolution, and even South American politics. I highly recommend it.
