In 1990, a group of Cambridge scientists arrived at the Plains of Nechisar in Ethiopia. On that expedition, they collected more than two dozen specimens, saw more than three hundred species of birds, and a plethora of rare butterflies, dragonflies, reptiles, mammals, and plants. As they were gathering up their findings, a wing of an unidentified bird was packed into a brown paper bag. It was to become the most famous wing in the world.This wing would set the world of science aflutter. Experts were mystified. The wing was entirely unique. It was like nothing they had ever seem before. Could a new species be named based on just one wing? After much discussion, a new species was announced: Nechisar Nightjar, or Camprimulgus Solala, which means "only wing." And so birdwatchers like Vernon began to dream.Twenty-two years later, he joins an expedition of four to find this rarest bird in the world. In this gem of nature writing, Vernon captivates and enchants as he recounts the searches by spotlight through the Ethiopian plains, and allows the reader to mediate on nature, exploration, our need for wild places, and the human compulsion to name things. Rarest Bird is a celebration of a certain way of seeing the world, and will bring out the explorer in in everyone who reads it.
