Migrating birds fly high, fast and far from the United States and Canada to Central and South America. But on a cloudy night, the sight of a red light on a communication tower can draw them in and hold them spellbound.

Nearly 7 million migrating birds die a year, victims of the 84,000 towers that dot the North American skyline, according to a University of Southern California study, funded in part by Defenders of Wildlife.

During stormy weather, clouds obscure the stars and force birds to fly at lower levels without their navigational tools. Blinking tower lights don’t confuse them. It’s the steady-burning red ones. The birds end up circling the tower and run into the dozens of cables, known as guy wires, that prop up a tower.

Researchers found the taller the tower, the greater the threat. Of the 84,000 communication towers in North America, only 1,000 or so rise above 900 feet, but they account for 70 percent of the tower-related bird deaths. “That amounts to a staggering 4.5 million birds each year,” says Chris Haney, Defenders’ chief scientist.

The study does offer some solutions: Change the steady-burning lights on tall towers, share towers and build freestanding towers to reduce the need for guy wires. “Methods to reduce this lethal mortality are the best long-term solution,” adds Haney.

A bumble bee pollinates a purple coneflower in Indiana.

Far from a bumbler, the bee is a productive pollinator with a reputation for diligence. That’s fortunate for us because close to 75 percent of flowering plants rely on insects to help them produce fruit and seeds.

And none does it better than a bee. That’s because most have fuzzy, feathery body hairs that carry an electrostatic charge to snag pollen. It’s not intentional. As bees feed, court or gather nectar, pollen sticks to their bodies and rubs off accidentally as they buzz from flower to flower, pollinating on the fly.

We rely on pollinators like the humble bumble bee for a full third of our food supply. Wildlife—from songbirds to grizzly bears—rely on them even more. Without them, we’d have no apples, blueberries, chocolate, coffee or orange juice, to name a few delicacies we’d have to forgo.

Given the importance of bees, their dramatic decline in recent decades is particularly alarming. Native bees from California to Maine have been disappearing because of habitat loss or degradation, pesticides and the spread of diseases and parasites. Massive honey bee die-offs—coined “colony collapse disorder” after it was first noticed in 2006—still have scientists puzzled and searching for a solution.

To keep the world abuzz and blooming, we must protect these vital pollinators.

Here’s what you can do to help bees:

• Provide nesting sites in your yard (untilled, unmulched, partially bare ground with leaf pieces or mud for nesting materials).
• Avoid pesticides.
• Advocate for bees with neighbors and local policymakers.

Sea otters frolic off the coast of California.

With their expressive faces and soft, furry bodies, sea otters exude charisma. But when it comes to survival, cute and cuddly doesn’t always cut it.

As few as 2,800 sea otters call California’s waters home. The population descends from a single remaining colony of about 50 hidden amid the crags of Big Sur, out of sight from fur hunters who nearly wiped out the world’s entire population by the early 1900s. Today they are at risk from pollution-caused disease, oil spills and fishing gear.

But even in such small numbers, these marine mustelids—related to weasels, ferrets and minks—have a profound influence on the marine ecosystem, keeping crucial kelp forests healthy by eating urchins that can overgraze. The otters’ diverse diet includes clams, crabs and mussels, which they cleverly crack open with a rock—every otter keeps one tucked away in a chest pouch.

Unlike most of their blubbery brethren, sea otters have fur—the densest of any mammal at up to 1 million hairs per square inch—to keep the chilly waters at bay. Because they can’t afford a bad hair day, much time is spent grooming their “do.” If their fur becomes soiled, it’s no longer waterproof and they can freeze to death. That’s one reason oil spills are so lethal.

Despite these amazing adaptations, California sea otters still need our help to keep their heads above water—so they can frolic and we can be charmed throughout this century and into the next.

Chimps…so cute, so funny…so full of character. Television advertisements, movies and even greeting cards rely on their antics to entertain. But the public sees them so frequently that many people don’t realize these great apes actually face extinction in the wild, according to a new study published this month in PLoS One, the journal of the Public Library of Sciences.

Using composite images to test respondents’ reactions to chimpanzees in different circumstances, researchers with the Lincoln Park Zoo in Chicago found that many people believed that chimps were thriving in the wild.

The media’s exploitation of chimpanzees can make people believe that the species doesn’t need protection, says Steve Ross, the study’s lead author and assistant director of the zoo’s ape center. And this could be undermining important conservation efforts for a severely endangered species that could go extinct in the wild in 10 to 50 years without more help.

The other sad reality is that a chimp’s “acting” career is over after only a few short years. As adults, they become too large and strong, unmanageable and dangerous. The lucky ones end up in sanctuaries. The star-crossed end their careers as roadside attractions in unaccredited zoos or in backyard cages or breeding compounds, according to the Florida-based Center for Great Apes. Michael Jackson’s former friend Bubbles is housed at this sanctuary, as are four of the chimps used in commercials that aired during the 2005 Super Bowl, Emmy Awards and Academy Awards. Chimps can live 50 to 60 years.

The good news is that in the last several years, at least 15 advertising agencies—including 10 of the top ad firms in the world—have agreed to pitch out the idea of using chimps as actors rather than pitch it for a new campaign.

What Can You Do?

Don’t let them entertain you. Avoid greeting cards that bear their photos, and don’t buy products or use the services of companies that exploit these endangered species.

Encourage others to do the same by spreading the word about this great apes’ plight.
