Tracks in the Sky : Wildlife and Wetlands of the Pacific Flyway, photographs by Tupper Ansel Blake, text by Peter Steinhart (San Francisco, CA : Chronicle Books, 1987). Out of print, but available used.
"The Pacific flyway is a reflection of the water below the sky. It is a chain of wetlands stretching from the Arctic to the tropics." -- from Tracks in the Sky : Wildlife and Wetlands of the Pacific Flyway
Although a bit dated, Tracks in the Sky : Wildlife and Wetlands of the Pacific Flyway is worth returning to each year. As we look to the skies and wetlands for migrating birds, it is a reminder of both the spectacle of migration and its fragility. The book ranges the Pacific Flyway, from the Arctic to Central America, stopping along the way to inform readers about wetlands and the wildlife that depends on them.
The photographs of Tupper Ansel Blake and the words of Peter Steinhart convey the beauty and mystery of the flyway -- "the river of birds."
Each Fall," Steinhart writes, "[the river of birds] moves like a falling veil over the north, as if some God had turned a basketful of creatures and watched them tumble over the horizon. Each spring, birds move in wedges and ribbons, pairs and clusters, from lake to lake, skulking over the upland forests, leapfrogging along the coasts. They are as much a part of the sky above us as the clouds and stars. And when they bump into our conscious minds, they startle us with the idea that there is life and will moving outside us.
Steinhart believes that seeing the beauty of migration encourages us to look for ways to save our diminishing wetlands.
Steinhart writes about the beauty of migration and wetlands, but he is also clear about what is being lost. He is unyielding in writing about what we are doing wrong. For instance, Steinhart spends an entire chapter explaining "the kindness of mud.." Mud, unpopular with humans, is what gives life to wetlands. "It is what makes the flyways work," Steinhart explains. "At least 75 percent of our bird species depend at some time on wetlands for breeding, staging, feeding, or loafing. Without mud, the great river of birds that passes back and forth across our skies in fall and spring would dry up." Mud is needed for flood control, groundwater recharge, and maintaining water quality. It affects the weather and global warming. "It is what keeps rivers and lakes and estuaries lively. It breathes oxygen, birds, and insects into the sky." Steinhart hopes that people will learn to let it be, to allow mud to "ooze and desiccate and slump and mumble at its own pace." If we learn to leave mud alone, Steinhart concludes, "there is hope for us as a species." If we don't, our wetlands and bird populations will continue to decrease.
There is cause for hope and discouragement in the history that unfolds in Tracks in the Sky. In March, 1903, Theodore Roosevelt began the National Wildlife System by "reserving and setting apart...Pelican Island as a preserve and breeding ground for native birds." By the end of his presidency, he had "created a total of fifty-three units of the National Wildlife Refuge System in seventeen states and territories." This sounds encouraging, but from the very beginning a lack of funding thwarted proper care of our wetlands. While attempts to protect migratory birds and wetlands has been ongoing, with some successes, Steinhart believes that we continue to "strangle the flyway." This is particularly true in California, "where 60 percent of the migratory birds of the Pacific flyway winter and where water "is funneled...into ditches and canals, and husbanded...narrowly to human purposes." "We are slowly strangling the flyway, Steinhart warns. "One day, we may look out over an endless plain of concrete and asphalt and glass and find that we have drained the skies."
Perhaps, some headway has been made since the 1987 publishing date of Tracks in the Sky. There seems to be a better understanding of the importance of wetlands. Some of the projects waiting for funding at the time Tracks in the Sky was published are now operating. Local groups come together to save local watersheds. Here, in California's Central Valley, there seems to be an attempt to increase our wetland areas, but at the same time more and more valley land is being urbanized. Steinhart's warnings seem current. "We talk," he writes, "of the value of lost wetlands in economic terms. We must also talk of values to our heart and minds." Tracks in the Sky : Wildlife and Wetlands of the Pacific Flyway is a book to return to each winter, as the migrating birds move along the Pacific and other flyways. It is a book to remember when you visit a wetland or watch a "v" of geese fly overhead.
"The arrival and departure of geese and sandpiper, swallow and eagle, open for us seams in the cosmos, pose for us the possibility of a dimension beyond our own reality, a destination we, our boots nailed to our floors, are powerless to leap into." -- from Tracks in the Sky : Wildlife and Wetlands of the Pacific Flyway
"...looking is one of life's great pleasures. To be aware of the light and line and color around you, to look long and thoughtfully at something, to read in a shorebird's plumage the marks of wind and water and time, is one of humankind's gifts. Simply being in a wetland offers us vast opportunities to see." -- from Tracks in the Sky : Wildlife and Wetlands of the Pacific Flyway
