Most rats live their lives entirely unseen by humans. As kings of the background, they often scurry through human environments just out of sight or after dark, looking for leftover morsels. But researchers believe rats might be picking up more than just our food crumbs — they could also be picking up on the beats in our music. A study published in 2022 suggests rats may have a humanlike sense of rhythm, which they express by bopping their heads to the beat. Scientists once believed that few animals were beat-sensitive (aside from some birds), but rats exposed to music made microscopic head movements that were picked up by tiny, wireless motion detectors. The researchers hypothesized that rats would prefer faster jams thanks in part to their rapid heartbeats, though surprisingly, lab rats synced up best with music in the 120 to 140 beats-per-minute range — just like humans.

Some rats can detect land mines.

It's a fact

Magawa, a trained African giant pouched rat, sniffed out more than 100 explosives in Cambodia before dying in 2022. Five years of mine-detecting work landed him a medal, though he wasn’t the only rat with a job; an organization called APOPO has trained hundreds to detect land mines.

Humans have long wondered if animals respond to music the way we do. Charles Darwin’s studies examined the relationship between animals and music, believing rhythm could be found throughout nature and may have been the precursor to music. Today, some experts believe only certain species have the ability to really respond to changing beats — notably bats, birds, dolphins, and elephants, which all have the complex ability to learn and repeat new sounds. However, some studies show other animals interact with music, too; one experiment found that pigs exposed to certain music became playful and wagged their tails. Additionally, many farmers report their cows are calmer when the radio is on, with a supporting study reporting that dairy cows produce 3% more milk while listening to slow tunes (fast music had no effect). And when it comes to our best pet companions, music is known to soothe anxious dogs in shelters and adoption centers, though felines — known for being a bit finicky — couldn’t care less about human music. However, they do respond positively to tailored tunes that use beats and frequencies similar to their own meows.

During his 82 years in the spotlight, the wildfire prevention mascot has kindled lots of goodwill. So much, in fact, that in 1964, the U.S. Postal Service created a unique ZIP code for Smokey Bear’s mail. Not bad for a mascot that started out as a purely fictional character. In 1944, working on a commission from the War Advertising Council and the U.S. Forest Service, Saturday Evening Post artist Albert Staehle and writer Harold Rosenberg crafted the reassuring, safety-conscious black bear, now the face of the country’s longest-running public service campaign, where he frequently shares his famous slogan: “Only you can prevent wildfires.”

Smokey Bear’s name used to be Smokey the Bear.

Smokey Bear has always been Smokey Bear. The confusion over his name likely stemmed from the song “Smokey the Bear,” written by Steve Nelson and Jack Rollins. They added “the” to fit the melody of the song, but it has never been an official part of his moniker.

In 1950, a 5-pound black bear cub rescued from a New Mexico wildfire by Taos Pueblo firefighters was christened “Smokey Bear” as a living homage to the popular protective figure. This bear spent the rest of his life at the National Zoo in Washington, D.C. There, he, his successor — Smokey II — and their alter ego received up to 13,000 letters, drawings, Christmas cards, and honey shipments each week. To help sort these deliveries, the bears were given their own Washington, D.C., ZIP code: 20252. Some of the mail was undoubtedly postmarked with Smokey Bear stamps, which were printed with the likenesses of the first two bears and released on the 40th anniversary of the character’s debut. From around 2007 to 2014, the ZIP code was decommissioned, but it was revived for the mascot’s 70th anniversary. The original bear also has his own Instagram account, where he shares fire prevention tips with the hashtag #OnlyYou — now a more vital message than ever.

Enlisting animals into military service isn’t entirely unusual — dolphins have been used for underwater surveillance and even camels have helped haul supplies. Those successes could be why a Coast Guard program meant to train pigeons for search and rescue missions was able to get off the ground in the late 1970s. Project Sea Hunt’s goal was to more easily (and quickly) find people lost at sea using trained pigeons to act as real-time spotters. Despite their reputation as nuisance fowl, pigeons are easily trainable creatures with outstanding eyesight; they (like many birds) may even have better vision than humans, thanks to their ability to see UV light.

There’s no scientific difference between pigeons and doves.

There’s not much difference between the birds beyond their name; the word “dove” has Nordic origins, while “pigeon” comes from French. Both birds belong to the Columbidae family and are often categorized by size, but the use of the terms is often subjective.

Pigeons selected for the program underwent six months of training to spot yellow, orange, and red objects in the ocean (the most common colors for flotation devices and rafts), and were then placed in special pigeon chambers underneath helicopters that had a view of the water below. When the trained birds spotted a bright color, they could signal to Coast Guard pilots above by pecking a special pedal that flashed a signal in the cockpit. Test runs found that the pigeons were able to spot targets 90% of the time, compared to the human success rate of just 38%. The pigeons were also faster than their human counterparts, spotting potential victims before humans did 84% of the time.

Despite these successes, Project Sea Hunt was shuttered due to federal budget cuts in the early 1980s. In the years since, the Coast Guard has combined flyovers, ocean-tracking software, and other methods to quickly and safely rescue those lost at sea.
