"Songbird Journeys pulls together in one readable book much of the
latest research on the fascinating lives of the songbirds. Anyone who
has been impressed or inspired by these tiny feathered jewels will be
more so after reading this book." —David Allen Sibley
One of the world’s most extraordinary wildlife migrations passes unseen
within hundreds of feet of our own neighborhoods—the night flights
of millions of songbirds. By dawn, these colorful migrants descend to our
backyards, urban parks, and forests, either to replenish themselves for the
rest of their trip or to settle in for the summer and raise their young.
Until recently, little
was known about the lives of songbirds during their travels from autumn until
spring. Aided by modern technology, however, scientists have documented mass
migrations over the Gulf of Mexico, identified the voices of migrants in the
night sky, and showed how songbirds navigate using stars, polarized light, and
magnetic fields.
Miyoko Chu explores the intricacies underlying the ebb and flow
of migration, the cycle of seasons, and the interconnectedness between distant
places. Songbird Journeys pays homage to the wonder and beauty of songbirds while
revealing the remarkable lives of migratory birds and the scientific quest to
answer age-old questions about where songbirds go, how they get there, and what
they do in the far-flung places they inhabit throughout the year.
• According
to the U.S. Forest Service, 70 million Americans go out at least once a
year to watch birds.
• Almost half the 10,000 bird species on Earth are songbirds,
including thrushes, swallows, warblers, sparrows, tanagers, blackbirds,
finches, crows, and jays.
• For migratory songbirds, life is short, and their journeys
dangerous. For some songbirds, more than 85 percent of annual deaths occur
during migration.
• A thrush can travel 3,000 miles from Panama to Canada,
its wings beating more than 600 times per minute or 3.2 million beats from
start to finish. It averages about 158 miles per night of flight, expending
just 0.3 calories per mile, including flights and stopovers.
