In the past two decades, our understanding of the navigational and
physiological feats that enable birds to cross immense oceans, fly
above the highest mountains, or remain in unbroken flight for
months at a stretch has exploded. What we've learned of these key
migrations-how billions of birds circumnavigate the globe, flying
tens of thousands of miles between hemispheres on an annual
basis-is nothing short of extraordinary. Bird migration entails
almost unfathomable endurance, like a sparrow-sized sandpiper that
will fly nonstop from Canada to Venezuela-the equivalent of running
126 consecutive marathons without food, water, or rest-avoiding
dehydration by "drinking" moisture from its own muscles and organs,
while orienting itself using the earth's magnetic field through a
form of quantum entanglement that made Einstein queasy. Crossing
the Pacific Ocean in nine days of nonstop flight, as some birds do,
leaves little time for sleep, but migrants can put half their
brains to sleep for a few seconds at a time, alternating sides-and
their reaction time actually improves. These and other revelations
convey both the wonder of bird migration and its global sweep, from
the mudflats of the Yellow Sea in China to the remote mountains of
northeastern India to the dusty hills of southern Cyprus. This
breathtaking work of nature writing from Pulitzer Prize finalist
Scott Weidensaul also introduces readers to those scientists,
researchers, and bird lovers trying to preserve global migratory
patterns in the face of climate change and other environmental
challenges. Drawing on his own extensive fieldwork, in A World on
the Wing Weidensaul unveils with dazzling prose the miracle of
nature taking place over our heads.
