Take a look at Magee Marsh, a 2,000-acre wildlife refuge on the Ohio shore of Lake Erie. “I look at them and go, ‘Thank you for working for us.’ ”. Farmers would be well advised, the report noted, to flood their fields and create wetlands for these avian wayfarers. Researchers noticed the birds’ necks drooping in the wild, a sign of debilitating weakness. They transported messages that helped the Allies capture German submarines, and that saved the crews of downed seaplanes and a sunken minesweeper. “There haven’t been very many rigorous tests—we still need more information on whether birds are going to well represent other components of biodiversity,” he says. • Seabird guano—rich in nitrogen, phosphorus, and other nutrients—“provides an important source of fertilizer and income to many people living near seabird colonies,” according to Utah’s Sekercioglu. Matt Johnson, a professor of wildlife habitat ecology at California’s Humboldt State University, has studied the birds in Jamaica’s Blue Mountains—a steep and meandering landscape that produces some of the world’s priciest coffee—and in the more rolling terrain where Kew Park is located. Fish and Wildlife Service calculated that, based on a 2006 survey, birders spend $12 billion annually on travel, plus an additional $24 billion on equipment like binoculars, camping gear, and nest boxes. Its large seeds feed grizzlies and black bears. Some might not realize the tangible value of birds, but it would be foolish to underestimate how tough life would be without them. And their canopy shades the snowpack, ensuring a protracted melt rather than a sudden springtime flush. Birds are very varied and they can eat anything from fruit to other birds and live anywhere from hedges to church steeples. There are no safe pesticides that kill the insects, and attempts to control them with parasitic wasps show, at best, limited success. A 2012 report by the Maine-based Biodiversity Research Institute (BRI) calls the birds “excellent sentinels of threats impacting aquatic ecosystems. In the 1990s a New York Zoological Society biologist computed that in the jungles of Peru “a single free-flying large macaw might generate $22,500 to $165,000 of tourist receipts in its lifetime.” Around the same time, researchers estimated the annual value of flamingo viewing in Kenya’s Lake Nakuru National Park at $2.5 million to $5 million. Tinkering with the environment disrupts these relationships. When birds are dependent on the habitat functioning in specific ways, the population trends of birds can tell us about how well the ecosystem functions. Johnson and his team set up nylon nets to keep the birds off individual plants (or small clusters). • Birds possess skills that historically made them useful to militaries. “The people were in despair. The durian munjit, a wild fruit that is collected and eaten in northern Borneo, relies exclusively on spiderhunters, members of the sunbird family. Without vultures around, feral dogs have taken over carcass disposal. “They will not stop manufacturing multi-dose vials voluntarily.”. “You know you have a healthy system,” she says, “when you have not just one species but 20 different species of birds.”. Or take action immediately with one of our current campaigns below: The Audubon Bird Guide is a free and complete field guide to more than 800 species of North American birds, right in your pocket. “Unfortunately,” Sekercioglu writes, guano production “is one of the most threatened of avian ecosystem services, due to the rapid decline of seabirds worldwide.” Among the culprits are fishing longlines, which entrap birds such as black-browed albatrosses. He calculated that the sites generated $26 million and created 283 jobs in 2011. In 2006, after a bird-friendly alternative drug was identified, India banned the veterinary use of diclofenac. The tiny insects take over individual berries and spend almost their entire life cycles inside, rendering those beans unsellable. There are many others: • After every harvest, California’s rice farmers must get rid of a waste product called rice straw. Can This Critically Endangered Bird Survive Australia's New Climate Reality? “I don’t think anyone knows what that would look like if vultures weren’t around to clean up a big portion.” Though scientists have long valued scavenging birds for their sanitation services, he says, “it’s pretty recently that we’ve begun to discover how that translates into human health.”, Some of that discovery has come the hard way—from a natural experiment playing out today in South Asia. Yet the local impact of birders can’t be fully measured in dollars. A ferry service now offers migration cruises. “After skinning, vultures would come, and within half an hour they would finish everything that is perishable from a carcass. But bird enthusiasts don’t add up to a social consensus. “It’s such a plus to find something in Mother Nature that is a total asset,” he says.

Birds are a group of warm-blooded vertebrates constituting the class Aves / ˈ eɪ v iː z /, characterized by feathers, toothless beaked jaws, the laying of hard-shelled eggs, a high metabolic rate, a four-chambered heart, and a strong yet lightweight skeleton.Birds live worldwide and range in size from the 5 cm (2 in) bee hummingbird to the 2.75 m (9 ft) ostrich.
