Mama Sekali takes good care of her 3-month old.

There's nothing like the magic of new motherhood, when you find yourself spending hours marveling at the incredible being you helped create and gazing at their impossibly tiny and adorable features. It's sweet when humans do it, but seeing animals have those kinds of tender moments with their babies is so endearing.

Sekali, a Sumatran orangutan who lives at the Toronto Zoo, gave birth to a baby in April 2022. In a video shared by the zoo, the baby gets some "tummy time" while Sekali gently strokes and cuddles him. "Sekali continues to take excellent care of her little one, and he appears to be more alert and mobile," the zoo shared. "Keepers are seeing the baby standing up while holding onto mom and sitting up on his own now, so he is growing stronger each day."

The little guy is cute cute cute, but Sekali picking up his foot and "kissing" it is the sweetest darn thing ever.

People gushed over the video on the zoo's Facebook page.

"LOOKS LIKE ALL MOMMA'S COUNTING THOSE LITTLE TOES AND FINGERS.... SHE APPEARS TO BE SUCH A TENDER MOM!! 🙂❤ I LOVE THIS!!!! 🙂" wrote one commenter.

"Clearly his Mom just adores him so much," wrote another. "She is such a good Mom.........he's so sweet and bright-eyed .....a happy and content little guy."

"I’m going to get in trouble for saying this, but, that little one is cuter than a lot of babies!!!! Just look how gentle she is with baby!!!" shared another.

A few months later in August 2022, the Toronto Zoo announced in a press release that the baby orangutan had been christened "Wali," which means "guardian" in Indonesian. Dolf Dejong, CEO of the Toronto Zoo, noted that the name was chosen from a batch of suggestions from the Wildlife Care keepers. Though there were many great suggestions, one stood out as the "clear winner," said DeJong. According to the Zoo's press release, the name felt "fitting since Sumatran Orangutans are the guardians of the rainforests."

While the Sumatran orangutans are seen as guardians, the sad truth is that the species is in trouble.

In 2017, Sumatran orangutans were moved from the International Union for Conservation and Nature (IUCN) Red List of Threatened Species' "endangered" category to "critically endangered," with their habitat in the wild threatened by deforestation, primarily due to palm oil plantations replacing rainforests. According to the Sumatran Orangutan Conservation Programme in 2022, there were only around 14,000 orangutans left in the wild. According to the World Wildlife Fund (WWF), that number has dipped even lower as of 2025.

Orangutan breeding in captivity is not without its controversy, however. The purpose of captive breeding programs like the Orangutan Species Survival Plan is not to release the animals into the wild, but rather to maintain genetic diversity, enable research, and educate the public about these magnificent creatures. Zoos have come a long way in recent decades, creating habitats that look and feel much less like cages and more like the wild, and studies have shown that zoos have a positive impact on people's interest in conservation. Orangutans in human care, like Sekali, may help motivate more people to care about what's happening to the species in their home habitats.

“We are incredibly excited to welcome this new addition to the Toronto Zoo family,” said DeJong. “This orangutan baby is an important contribution to a genetically healthy Sumatran orangutan population in human care. Meanwhile, Sumatran orangutans are under increasing pressure in the wild due to habitat loss and the palm oil crisis, which we are working with partners to address. We are proud to play an important role in the conservation of this amazing species.”

Today, Wali is thriving with mama Sekali and dad Budi. A compilation of his "adorable antics" was shared on YouTube in early January, showing the public what Wali has been up to the last few years. Watch:

Here's the first ever footage of a baby sperm whale nursing from its mother

How baby sperm whales nurse has been a scientific mystery for decades.

We know that mammals feed their young with milk from their own bodies, and we know that whales are mammals. But the logistics of how some whales make breastfeeding happen has been a bit of a mystery for scientists. Such has been the case with sperm whales.

Sperm whales are uniquely shaped, with humongous, block-shaped heads that house the largest brains in the animal world. Like other cetaceans, sperm whale babies rely on their mother's milk for sustenance in their first year or two. And also like other cetaceans, a sperm whale mama's nipple is inverted—it doesn't stick out from her body like many mammals, but rather is hidden inside a mammary slit.

Most whale and dolphin babies nudge the mammary slit to expose the nipple, allowing them to "suckle." A sperm whale baby's head and mouth aren't really designed for suckling in the traditional sense, obviously, as its massive nose protrudes over its much smaller lower jaw. But even in the whale sense of mom shooting milk into a baby's mouth, it's been unclear how it works for sperm whales due to their oddly shaped heads. Photos and observations have led researchers to believe that the mother whale expresses milk into the water for the baby to ingests outside of her body, but the real mechanics haven't been clearly understood.

With the proliferation of underwater photography and filmography, it may seem strange that we don't have more nursing whale evidence to examine, but because baby whales can't breathe and nurse at the same time, nursing events are usually quite short. Even being in the right place at the right time to observe a whale nursing is rare, much less capturing it on film.

A four-part documentary series from National Geographic has provided, for the first time, film footage of a sperm whale baby nursing. It shows how the baby actually inserting its lower jaw into the mother's mammary slit, and the milk—which contains ten times more fat than human milk and is the consistency of yogurt—shooting directly into the baby whale's mouth.

The documentary series containing this footage, "Secrets of the Whales," was conceived of by National Geographic Explorer and photographer Brian Skerry and follows the stories of five different whale species—narwhals, humpbacks, belugas, sperm whales, and orcas. It was filmed in 24 locations around the world and took three years to make. Produced by award-winning filmmaker and conservationist James Cameron (of "Titanic" and "Avatar" fame) and narrated by award-winning actress and conservationist Sigourney Weaver, the series is sure to please whale lovers and nature lovers alike.

In addition to sperm whale babies breastfeeding, the docuseries shows how beluga whales name themselves so groups can keep track of each other, how baby belugas share their moms' call signs, how 30,000 humpbacks travel together from Australia to Antarctica and use breeches to talk to each other, and how a beluga pod adopted a narwhal into their bod—apparently the first ever cross-species adoption ever recorded.

Executive Producer James Cameron called the series a "challenging, daunting project" in a SXSW Conference panel last month."It's also so important for people to understand and for this film to illuminate how these creatures think, how they feel, what their emotion is like, what their society is like," he said, "because we won't protect what we don't love."

The series premiers on streaming service Disney+ on Earth Day, April 22.

The filmmakers hope that by sharing with people the unique identities of the whales they followed, they can inspire people to think about how these magnificent mammals can be better protected.

"It's inescapable that they're being poisoned by us, that they're being deafened by us, or their behaviors, all of their feeding strategies and mating strategies and reproductive strategies are being dismantled by all of this noise from shipping channels and military sonars and all that," Cameron said. "They're going to continue to decline. The right whales are down to about 300…We barely understand these animals, so I think we have to, as a society, we have to think about doing it better."

Indeed we do.

Science

A juice company dumped orange peels in a national park. Here's what it looks like now.

12,000 tons of food waste and 21 years later, this forest looks totally different.

In 1997, ecologists Daniel Janzen and Winnie Hallwachs approached an orange juice company in Costa Rica with an off-the-wall idea. In exchange for donating a portion of unspoiled, forested land to the Área de Conservación Guanacaste — a nature preserve in the country's northwest — the park would allow the company to dump its discarded orange peels and pulp, free of charge, in a heavily grazed, largely deforested area nearby.

One year later, one thousand trucks poured into the national park, offloading over 12,000 metric tons of sticky, mealy, orange compost onto the worn-out plot. The site was left untouched and largely unexamined for over a decade. A sign was placed to ensure future researchers could locate and study it.


16 years later, Janzen dispatched graduate student Timothy Treuer to look for the site where the food waste was dumped.

Treuer initially set out to locate the large placard that marked the plot — and failed.

"It's a huge sign, bright yellow lettering. We should have been able to see it," Treuer says. After wandering around for half an hour with no luck, he consulted Janzen, who gave him more detailed instructions on how to find the plot.

When he returned a week later and confirmed he was in the right place, Treuer was floored. Compared to the adjacent barren former pastureland, the site of the food waste deposit was "like night and day."

"It was just hard to believe that the only difference between the two areas was a bunch of orange peels. They look like completely different ecosystems," he explains.

The area was so thick with vegetation he still could not find the sign.

Treuer and a team of researchers from Princeton University studied the site over the course of the following three years.

The results, published in the journal "Restoration Ecology," highlight just how completely the discarded fruit parts assisted the area's turnaround.

The ecologists measured various qualities of the site against an area of former pastureland immediately across the access road used to dump the orange peels two decades prior. Compared to the adjacent plot, which was dominated by a single species of tree, the site of the orange peel deposit featured two dozen species of vegetation, most thriving.

In addition to greater biodiversity, richer soil, and a better-developed canopy, researchers discovered a tayra (a dog-sized weasel) and a giant fig tree three feet in diameter, on the plot.

"You could have had 20 people climbing in that tree at once and it would have supported the weight no problem," says Jon Choi, co-author of the paper, who conducted much of the soil analysis. "That thing was massive."

Recent evidence suggests that secondary tropical forests — those that grow after the original inhabitants are torn down — are essential to helping slow climate change.

In a 2016 study published in Nature, researchers found that such forests absorb and store atmospheric carbon at roughly 11 times the rate of old-growth forests.

Treuer believes better management of discarded produce — like orange peels — could be key to helping these forests regrow.

In many parts of the world, rates of deforestation are increasing dramatically, sapping local soil of much-needed nutrients and, with them, the ability of ecosystems to restore themselves.

Meanwhile, much of the world is awash in nutrient-rich food waste. In the United States, up to half of all produce in the United States is discarded. Most currently ends up in landfills.

"We don't want companies to go out there will-nilly just dumping their waste all over the place, but if it's scientifically driven and restorationists are involved in addition to companies, this is something I think has really high potential," Treuer says.

The next step, he believes, is to examine whether other ecosystems — dry forests, cloud forests, tropical savannas — react the same way to similar deposits.

Two years after his initial survey, Treuer returned to once again try to locate the sign marking the site.

Since his first scouting mission in 2013, Treuer had visited the plot more than 15 times. Choi had visited more than 50. Neither had spotted the original sign.

In 2015, when Treuer, with the help of the paper's senior author, David Wilcove, and Princeton Professor Rob Pringle, finally found it under a thicket of vines, the scope of the area's transformation became truly clear.

"It's a big honking sign," Choi emphasizes.

19 years of waiting with crossed fingers had buried it, thanks to two scientists, a flash of inspiration, and the rind of an unassuming fruit.
