You think your morning commute’s a beast? Try traversing the continent twice a year ... under your own steam.
Billions of birds do just that, migrating between warm winter climes and breeding grounds, often in the far North. And thanks to a growing human footprint, migratory birds face unprecedented threats with every journey.
At least 40 percent of all bird species are migratory. In North America more than 300 bird species migrate. Here are just a few amazing facts about the planet's migratory marvels:
High flyers — Bar-headed geese routinely traverse the Indian Himalayas, reaching altitudes of nearly 30,000 feet.
Far flyers — Arctic Terns are the globetrotting champs. Their annual round-trip transit amounts to nearly 50,000 miles per year.
Fast flyers — Great Snipes routinely maintain speeds of 60 mph or more on their 4200-mile migrations. And that’s without tailwinds.
Tireless flyers — the Bar-tailed Godwit exhibits world spanning feats of non-stop flight, able to cover 7,000 miles across the central Pacific without food or rest.
Fat flyers — feats of migration take a lot of calories, and birds often gorge themselves in preparation for the journey. Blackpoll Warblers, for instance, nearly double their body weight before embarking on their nonstop 2300-mile trip.
Navigating a Gauntlet of Death
Migrating birds face a host of natural dangers. Many die along the way. And ever-greater numbers are succumbing to unnatural dangers as well — habitat loss, tall buildings, pollution and climate change. For instance, in this country alone, window strikes are estimated to kill upwards of a billion birds every year.
“Earth provides enough to satisfy every man's needs, but not every man's greed.”
