What Do Ants Do With the Leaves They Carry Around?

If you’ve ever seen a line of leaf-carrying ants marching by, you may think that they’re heading somewhere quiet so they can chow down on their salads in peace. But the ants have no intention of eating those leaves—their plans are far grander (and smarter) than that.

The video above, which comes to us via KQED’s “Deep Look,” examines the ingenious habits of leafcutter ants, who actually use the leaves for the purposes of farming. The ants cut and carry the leaves to their underground colonies. (As mentioned in the video, an ant carrying one of these leaves is the equivalent of a human hauling 600 pounds above his or her head.)

In their nests, the ants prepare and arrange the leaves before fertilizing them with their own fecal matter. Fungus begins to grow on the leaves, and soon the ants are tending to a fungus farm that grows nutritional food for the colony.

Check out the video above for more on the fascinating world of leafcutter ants, including a rundown on their various roles, which the narrator says amounts to “the most complex division of labor of any [species of] ant.”

Watch This Live Stream to See Two Rare Penguin Chicks Hatch From Their Eggs

Bringing an African penguin chick into the world is an involved process, with both penguin parents taking turns incubating the egg. Now, over a month since they were laid, two penguin eggs at the National Aviary in Pittsburgh, Pennsylvania are ready to hatch. As Gizmodo reports, the baby birds will make their grand debut live for the world to see on the zoo's website.

The live stream follows couple Sidney and Bette in their nest, waiting for their young to emerge. The first egg was laid November 7 and is expected to hatch between December 14 and 18. The second, laid November 11, should hatch between December 18 and 22.

"We are thrilled to give the public this inside view of the arrival of these rare chicks," National Aviary executive director Cheryl Tracy said in a statement. "This is an important opportunity to raise awareness of a critically endangered species that is in rapid decline in the wild, and to learn about the work that the National Aviary is doing to care for and propagate African penguins."

African penguins are endangered, with less than 25,000 pairs left in the wild today. The National Aviary, the only independent indoor nonprofit aviary in the U.S., works to conserve threatened populations and raise awareness of them with bird breeding programs and educational campaigns.

After Sidney and Bette's new chicks are born, they will care for them in the nest for their first three weeks of life. The two penguins are parenting pros at this point: The monogamous couple has already hatched and raised three sets of chicks together.

Bleat Along to Classic Holiday Tunes With This Goat Christmas Album

Feeling a little Grinchy this month? The Sweden branch of ActionAid, an international charity dedicated to fighting global poverty, wants to goat—errr ... goad—you into the Christmas spirit with their animal-focused holiday album: All I Want for Christmas is a Goat.

Fittingly, it features the shriek-filled vocal stylings of a group of festive farm animals bleating out classics like “Jingle Bells,” “Rudolph the Red-Nosed Reindeer,” and “O Come All Ye Faithful.” The recording may sound like a silly novelty release, but there's a serious cause behind it: It’s intended to remind listeners how the animals benefit impoverished communities. Goats can live in arid nations that are too dry for farming, and they provide their owners with milk and wool. In fact, the only thing they can't seem to do is, well, sing. 

You can purchase All I Want for Christmas is a Goat on iTunes and Spotify, or listen to a few songs from its eight-track selection below.
