Trash, much of it believed to be debris from the 2011 Japanese tsunami, litters the beach on Montague Island, Alaska, on Jan. 26.

Refrigerators, foam buoys and even ketchup bottles are piling up on Alaska's beaches. Almost two years after the devastating Japanese tsunami, its debris and rubbish are fouling the coastlines of many states — especially in Alaska.

At the state's Montague Island beach, the nearly 80 miles of rugged wilderness looks pristine from a helicopter a few thousand feet up. But when you descend, globs of foam come into view.

The last few years have been especially tough in South Florida for wading birds such as egrets, herons, ibises and wood storks that feed and nest in the region's wetlands.

The problem is there are fewer wetlands, and the last few years have been dry, reducing water levels in critical areas.

Stand aside Beyonce, there's a new sound in town. More than 9,000 sounds, to be more precise. The Macaulay Library at the Cornell Lab of Ornithology has just finished digitizing its huge archive of wildlife sounds and made it available online.

"It represents the voice of the world — all the voices of the world," Greg Budney, audio curator for the archive, tells NPR's Scott Simon. Among the vast collection are birds, mammals, insects and amphibians, Budney says, all made available "to anyone who has an interest in nature, in conservation and in the world around them."

Birds May Use 'Sound Maps' To Navigate Huge Distances

Originally published on Fri February 1, 2013 7:17 pm

MELISSA BLOCK, HOST:

Now the curious case of the homing pigeon and the mystery of just how they do what they do: navigate over huge distances to find their way home. We know they use the sun and the Earth's magnetic field. Well, Jonathan Hagstrum of the U.S. Geological Survey believes the birds also use sound maps. His study was recently published in the Journal of Experimental biology. And he joins us now to explain how he thinks this works. Welcome to the program.

DR. JONATHAN HAGSTRUM: Thank you.

I don't blame professional footballers for suing the NFL for supposedly having failed adequately to protect them from head injury.

That's the way we do things in our society. We see a problem and start suing; it's our way of trying to figure out what changes need to be made and whose insurance companies are going to pay for them.

Are We Losing The Race Against Climate Change?

China burns nearly as much coal as the rest of the world combined--and has 300 more coal plants in the works. But China also leads the world in solar panel exports and wind farms, and has a national climate change policy in place. Is the U.S. falling behind on climate? Ira Flatow and guests discuss how the world is tackling global warming--with or without us--and what it might take to change the climate on Capitol Hill.

Has the recession made you fat?

To the long and growing list of risk factors known to increase the risk of obesity, scientists recently added a new one: scarcity.

People given subtle cues that they may have to confront harsh conditions in the near future choose to eat higher-calorie food than they might do otherwise, a response that researchers believe is shaped by the long hand of evolution.
