Why Can Parrots Talk?

Did you know that birds are the only animals other than humans who can produce human language? Some species (SPEE-shees) or kinds of birds can copy sounds they hear in their environment, and even imitate a few words. Crows, mynah birds, ravens, and hummingbirds can all copy some of the sounds they hear. But the birds that are best at imitating human speech are parrots. They can learn to say hundreds of words, and they understand what some of the words mean. One amazing African Grey parrot named Einstein, who lives at the Knoxville Zoo in Tennessee, can say about 200 words. 

About half of the bird species sing. They learn these songs from other birds. They can do this because of a part of their brain called the "song system." Inside this song system is a part called the “inner core.” The inner core is essential (ee-SENT-chall) or really important to helping these birds learn how to make sounds. Parrots also have an extra part of the song system called an “outer shell.” Scientists think the outer shell helps parrots be really good at copying sounds. But they're not sure exactly how it works.  

Parrots are social animals, which means they want to fit in with the rest of their friends. In the wild, parrots usually make bird sounds because they are surrounded by other birds. But around humans, parrots often imitate human words because they see their owners as part of their new family, or “flock.” They copy human sounds to fit in with their human flock. But parrots are also really smart. African Grey parrots like Einstein are as smart as a 5-year-old human! With training, some parrots can learn the meanings of words, the names of their favorite foods, and even count up to eight.

Watch a Gulper Eel Inflate Like a Terrifying Balloon

Since launching in 2008, the Ocean Exploration Trust's Nautilus research vessel has live-streamed a purple orb, a transparent squid, and a stubby octopus from the bottom of the ocean. The latest bizarre example of marine life captured by the vessel is a rare gulper eel that acts like a cross between a python and a pufferfish.

As Thrillist reports, this footage was shot by a Nautilus rover roaming the Pacific Ocean's Papahanaumokuakea Marine National Monument 4700 feet below the surface. In it, a limbless, slithery, black creature that looks like it swallowed a beach ball can be seen hovering above the sea floor. After about a minute, the eel deflates its throat, swims around for a bit, and unhinges its jaw to reveal a gaping mouth.

The reaction of the scientists onboard the ship is just as entertaining as the show the animal puts on. At first they're not sure what they're looking at ("It looks like a Muppet" someone says), and after being blown away by its shape-shifting skills, they conclude that it's a gulper eel. Gulper eels are named for their impressive jaw span, which allows them to swallow prey much larger than themselves and puff up to intimidate predators. Because they like to lurk at least 1500 feet beneath the ocean's surface, they're rarely documented.

You can watch the inflated eel and hear the researcher's response to it in the video below.
