Animal migration is a powerful sight: a mile-long blanket of cranes emerging from a Nebraska river and filling the sky; millions of wildebeests marching around the Serengeti; a blaze of orange as hundreds of thousands of monarch butterflies unfold their wings to take flight. Nature’s nice migrations have captivated numerous spectators, none extra so than optimum ecologist David S. Wilcove. under no circumstances domestic, his awe is palpable—as are the transforming into threats to migratory animals.
 
We should be witnessing a loss of life phenomenon between many species. Migration has continuously been hard, yet today’s tourists face unparalleled risks. Skyscrapers and cellphone towers entice birds and bats to premature deaths, fences and farms block herds of antelope, salmon are stuck en path among ocean and river, breeding and wintering grounds are paved over or plowed, and worldwide warming disrupts the synchronized schedules of predators and prey. the result's a dramatic decline within the variety of migrants.
 
Wilcove courses us on their treacherous trips, describing the boundaries to migration and exploring what compels animals to maintain on hiking. He additionally brings to existence the adventures of scientists who examine migrants. usually as daring as their matters, researchers velocity wildly alongside abandoned roads to trace birds hovering overhead, discover glaciers looking for frozen locusts, and outfit dragonflies with transmitters weighing under one one-hundredth of an ounce.
medical discoveries and complex applied sciences are aiding us to appreciate migrations greater, yet by myself, they won’t cease sea turtles and songbirds from going the best way of the bison or passenger pigeon. What’s required is the dedication and cooperation of the far-flung international locations migrants cross—long sooner than extinction is a chance. As Wilcove writes, “protecting the abundance of migration is vital to preserving the respect of migration.” No method domestic deals strong suggestion to maintain these wonderful journeys.
