"Illuminating. . . . Flight Paths does what only the best science books do: It adds to our knowledge of the world without diminishing its wonder."—Wall Street Journal

The captivating, little-known true story of a group of scientists and the methods and technology they developed to uncover the secrets of avian migration.

For the past century, scientists and naturalists have been steadily unravelling the secrets of bird migration. How and why birds navigate the skies, traveling from continent to continent—flying thousands of miles across the earth each fall and spring—has continually fascinated the human imagination, but only recently have we been able to fully understand these amazing journeys. Although we know much more than ever before, even the most enthusiastic birdwatcher may not know how we got here, the ways that the full breadth of scientific disciplines have come together to reveal these annual avian travels.

Flight Paths is the never-before-told story of how a group of migration-obsessed scientists in the twentieth and twenty-first centuries engaged nearly every branch of science to understand bird migration—from where and when they take off to their flight paths and behaviors, their destinations and the challenges they encounter getting there. Uniting curious minds from across generations, continents, and disciplines, bird enthusiast and science writer Rebecca Heisman traces the development of each technique used for tracking migratory birds, from the first attempts to mark individual birds to the cutting-edge technology that lets ornithologists trace where a bird has been, based on unique DNA markers. Along the way, she touches on the biggest technological breakthroughs of modern science and reveals the almost-forgotten stories of the scientists who harnessed these inventions in service of furthering our understanding of nature (and their personal obsession with birds).

The compelling and fascinating story of how scientists solved the great mystery of bird migration, Flight Paths is an unprecedented look into exciting, behind-the-scenes moments of groundbreaking discovery. Heisman demonstrates that the real power of science happens when people work together, focusing their minds and knowledge on a common goal. While the world looks to tackle massive challenges involving conservation and climate, the story of migration research offers a beacon of hope that we can find solutions to difficult and complex problems.

      How do birds manage to fly thousands of miles each fall and spring, spanning continents and oceans? As science writer and self-proclaimed bird nerd Heisman explains, in recent decades dedicated scientists have thrown themselves into answering that question, investigating takeoff and landing points, flight paths, and the challenges along the way. For all those bird watchers out there; with a 60,000-copy first printing.

      Starred review from January 30, 2023
      Science writer Heisman debuts with a winning examination of the seasonal movements of birds, tracing how scientific understanding of bird migration has evolved and detailing the technologies that ornithologists employ to study them today. Highlighting improbable theories proposed throughout history, she notes that Aristotle believed some “winter and summer residents were in fact the same birds in different plumages,” a 16th-century Swedish priest thought swallows hibernated at the bottom of lakes, and an English minister postulated that birds wintered on the moon. Contemporary scientists, the author notes, track flocks via radar and search for clues about where a bird traveled from by analyzing deuterium (“a very special type of hydrogen atom”) isotopes in feathers and matching them to regional variations in deuterium levels. She profiles the ornithologists behind these advances and tells how, for instance, evolutionary biologist Thomas Smith built on genome-sequencing technology to map genetic variation in warblers, finding that distinct genetic groups follow different migratory routes. Heisman pulls off the impressive feat of making technical discussions of genome sequencing and isotope analysis accessible, and the profiles offer revealing glimpses into the process and production of scientific knowledge. Admirers of Scott Weidensaul’s A World on the Wing will find this a treat.

      An in-depth look at how scientists track bird migration. Modern technology for tracking migratory birds can sound like something out of science fiction--e.g., analyzing the hydrogen isotopes of a single feather can indicate the breeding range of a particular species. Weather data can show their migration patterns on radar, and minuscule devices can be implanted under feathers, using the movement of the sun to determine their location. Earlier techniques, on the other hand, bordered on the mystical: moon-watching parties, for example, where ornithologists would spend hours with a telescope, waiting for a bird to fly across the full moon. In her debut book, Heisman, who studied zoology in college and has worked with a variety of bird-related groups, including the American Ornithological Society, "the world's largest professional organization for scientists who study birds," creates a skillful and accessible narrative about how we research and understand bird migration, from the first birds ever to be banded to current methodologies. As the author shows, community science, where people who track birds as a hobby contribute essential data, is more important than ever in the current era of dramatic climate change. "Although tiny transmitters, mass spectrometers, and Doppler radar stations are great," notes Heisman, "if you have a smartphone in your pocket, you already have all the equipment you need to join the cause of studying and conserving migratory birds." With apps like eBird, it's easy to track bird species and locations, providing valuable insight into migration patterns and disruption. In North America, bird populations have declined by nearly 30% since 1970, so initiatives for better understanding migration patterns are more important than ever. As Heisman asserts, "in the Anthropocene, even birds capable of the most extreme physiological feats will need human help to survive into the future." Understanding and tracking bird migration is the first step. A fascinating treat for avid bird-watchers.
