Ecologist 'burst into tears' seeing endangered gliders using boxes designed to save them

A third of the greater gliders' remaining habitat was destroyed in the Australian wildfires, and researchers didn't know if their high-tech box idea would work.

Greater gliders are endangered in Australia and rely on old-growth tree hollows to make their nests.

When a team of Australian researchers started checking the high-tech boxes they'd installed to help save endangered greater gliders, they weren't sure what they were going to find. The hope was that the tree-dwelling marsupials would use them for nesting—a replacement for the tree hollows they normally nest in—but no one knew whether or not the creatures would take to them.

So when Dr. Kita Ashman, Threatened Species and Climate Adaptation Ecologist at WWF-Australia, found a glider in the second box she checked, she was thrilled.

"I just burst into tears, I was so surprised and so happy," she told ABC News Australia.

Greater gliders are nocturnal marsupials that live in old-growth forests of eastern Australia. They have large ears, fluffy fur, long tails, and they can glide up to 100 meters at a time. The species is only found in Australia.

"I grew up looking at greater gliders all throughout the Dandenong Ranges. So they have a really special place in my heart," said Dr. Ashman told ANU.

The special nesting boxes were designed and created through a partnership between Australian National University (ANU), Greening Australia and the World Wide Fund for Nature-Australia after bushfires destroyed a third of the greater gliders' remaining habitat. The tree hollows that greater gliders rely on to nest can take over 100 years to form, according to ANU, so it's not like they can just find some new trees to live in when their homes are destroyed.

Nesting boxes that are commonly used for wildlife aren't a good fit for greater gliders, as the thin walls and lack of thermal protection can result in gliders overheating. (Heat-stressed gliders will slow their eating, which can be life-threatening, according to ANU.) The high-tech boxes in this project are insulated and include a non-toxic, heat-reflective, fire-resistant coating to keep gliders safe.

"I've affectionately been calling this design the Goldilocks box because we hope it will keep greater gliders not too hot and not too cold and will help to increase the species' resilience in a changing climate," Ashman said in July 2022.

"Producing and installing high-quality nest boxes is costly," added ANU research fellow Dr. Kara Youngentob, "so this project is very important because it will help us understand if expensive interventions like nest boxes are the best use of funding in our urgent mission to save greater gliders."

It appears that their efforts are paying off.

"What we didn't know was whether these boxes worked and whether they have an impact on the glider population," Dr. Youngentob told ABC News Australia. "Much to our delight, within a few months of them going up they are already being used by gliders, so we know the individuals themselves like them and use them."

According to Youngentob, greater gliders are the largest gliding marsupial at risk of extinction. More than 200 nesting boxes have been installed in Victoria's East Gippsland and in Tallaganda National Park in New South Wales. Youngentob told ABC News Australia that this project will help researchers learn more about how many of the species are left in the wild.

The quiet, nocturnal marsupial faces threats from climate change and deforestation in addition to the wildfires that ravaged Australia in 2020. Their population has fallen by 80% in the past 20 years and the species reached endangered status in July of 2022.

"They're a treasure for this country." Dr. Youngentob told ANU. "And I think the more people know about them, the more that they will fall in love with them and want to protect them too."

I can't remember the last time I went to a store—say a Target, Walmart, or a big chain grocery store—and didn't encounter roving gangs of birds in the parking lot. Sometimes it's only a few pigeons picking at crumbs and discarded sandwiches, and sometimes it's hundreds of seagulls fanning out like you might sometimes see them on the beach. Sometimes it's even geese, who are notoriously the meanest of the bunch. I've always been curious about why birds love parking lots so much, but never gave it a lot of thought.

Then I realized this is a phenomenon that has been happening all over the country for years. Not just gatherings of birds, but in some cases literal takeovers! Stories out of Texas and Louisiana show crows and grackles invading large parking lots by the thousands, making for amazing viral social media moments.

What in the Alfred Hitchcock is going on here? I wish I could ask the birds what's so appealing about asphalt parking lots? Well, I can't; but I can consult with bird experts.

There are four main reasons birds gather in large numbers in parking lots. First? They look like bodies of water.

I've always thought it was weird that waterbirds like seagulls, ducks, geese, and grebes are so common in parking lots.

The Audobon Society (bigtime bird folks) writes, "To a bird flying at night, [parking lots] resembles bodies of water, especially if their surfaces are wet. Even more so if made to glisten by artificial light." Even during the day, it's easy to see how a big patch of asphalt could look like a lake or pond to a flying bird. It makes sense that they'd want to land there and check it out.

Did you know that some waterbirds like certain kinds of grebes, loons, and swifts have trouble taking off from land due to the composition of their bodies? That means the presence of these confounding-looking parking lots can, sadly, cause some waterbirds to get stranded.

Second: They are open and safe from predators.

Being out in the open when you're a small, vulnerable bird seems like a bad idea, but it might actually be brilliant.

"Most of the bird species mentioned (e.g. Canada geese, seagulls, grackles) tend to find safety in numbers, and in parking lots, as well as open fields, it is easier for the group to be aware of predators, since there are not a lot of places to hide," says Dr. Allison Sacerdote-Velat, Curator of Biology and Herpetology and VP of Conservation Research at the Peggy Notebaert Nature Museum.

That helps explain not just birds' presence in parking lots, but their sometimes extremely large numbers! In a big group, they can help lookout for one another.

Well-lit parking lots are also a safe place for birds to hang out at night. Crows, for example, are a common food source for owls—a predator with notoriously excellent night vision. Crows don't operate as well at night so they sometimes descend on parking lots with bright artificial lights for better visibility and protection.


Three: They're full of free food.

Oh, do we humans love to litter in parking lots! They seem to make an excellent place to toss half a hot dog, a gristly chicken nugget, or dump out our toddler's snack bowl.

That makes parking lots relative buffets for birds who like to scavenge for food. It's a lot easier to wait for humans to drop something than it is to go hunting around for insects and seeds. Parking lots, though, just so happen to have a lot of that kind of food too—most big box parking lots have trees, shrubs, and bushes around the periphery which gives cover and access to natural food sources for birds.

Parking lots also collect puddles which can be used as a water source or a way to grab a quick bath.

Four: Their usual habitats are disappearing thanks to humanity and climate change

Probably the saddest reason that birds love to gather in parking lots is that they often don't have another choice.

"Habitats such as mudflats, plains, and old fields would provide a similar resource," as parking lots, according to Sacerdote-Velat, but those natural ecosystems are getting harder and harder to come by. If you live in an urban or suburban area (with plenty of parking lots) you've probably seen rapid expansion that's cleared out fields and trees to make room for more development. This habitat destruction has been a major factor in the overall bird population in the United States declining by almost 3 billion since 1970—a staggering, heartbreaking number.

Some people get annoyed or even frightened by large numbers of birds in parking lots. To be fair, grackles—big-time parking lot birds—can be fairly aggressive, as can geese. It's not fun navigating your way around a flock of stubborn and feisty birds when you're just trying to grab a shopping cart and run your errands!

But remember, they're just looking for a safe space to not get eaten by an owl. It's not their fault all the open fields and mudflats are gone—it's ours. The least we can do is respectfully share the back half of our Walmart parking lots with them. Just don't feed them old French fries or even bird seed. They're crafty foragers, these parking lot birds, and they'll do just fine with a couple hundred of their brethren helping them keep a lookout.

A wild goose was taken to an animal hospital. His mate knocked on the door to find him.

"We opened the door and gave Arnold his flow-by oxygen in the doorway. His mate immediately calmed down and began to groom him through the door."

Ahh, love.

As if a Canada goose named Arnold isn't endearing enough, his partner who came looking for him when he was injured is warming hearts and having us root for this sweet feathered couple.

Cape Wildlife Center in Barnstable, Massachusetts shared the story on its Facebook page in 2021, in what they called "a first" for their animal hospital.

"We often have people ask if they can visit the patients they dropped off, but today we had our first animal visitor!" they wrote. "For the safety of our patients we do not accommodate visitation requests, but in this case we had to make an exception!"

Arnold is a Canada goose that lives on a pond near the facility and is part of a mated pair of wild geese that have been together for several years. The center said the geese usually keep to themselves, but one of their staff noticed that Arnold was walking with a "significant limp" and kept falling over. They were able to capture him and bring him into the hospital for examination.

"Upon exam our veterinary team found that he had two open-fractures on his foot," they wrote. "This means that the tissue and skin has been pulled away leaving the bone exposed. Our best guess is that a Snapping turtle or other predator attacked him while swimming."

To save his foot and help him survive, the staff knew they had to amputate one of the digits and suture the other wound closed. They gave him antibiotics and pain meds and prepped him for surgery the following morning. Then his mate came knocking.

"Today, as we prepared to sedate Arnold and get him ready for surgery, we heard a faint tapping at the clinic door," the center wrote. "We turned to see that his mate had waddled up onto the porch and was attempting to break into our clinic! She had somehow located him and was agitated that she could not get inside. She remained there throughout the entire procedure, watching us work, never moving from the doorway."

Aww.

Surgery went well, and once Arnold woke up the staff decided to let him recover by the doorway so he and his mate could see each other.

"We opened the door and gave Arnold his flow-by oxygen in the doorway. His mate immediately calmed down and began to groom him through the door. They both seemed much more at ease in each other's presence."

AWWWW.

"Arnold will likely need several weeks of treatment in our hospital before he is ready to rejoin his mate in the wild," they added. "He will need to be kept inside for the majority of this time in order to keep his wound sterile and prevent infection. We will do our best to get him back out quickly and will perform bandage changes and treatments in view of the doorway when possible so that his mate can check up on him. ❤️"

While attempting not to anthropomorphize too much, it's so sweet to see animal partners show such genuine care for one another. Canada geese mate for life, and they are known to mourn in seclusion when they lose a mate. Seeing Arnold's mate coming to find him and comfort him during his treatment is just too lovely.

According to CBS News, Arnold was released to the wild and his mate, whom the hospital lovingly named Amelia, just a few weeks later. Feel good story of the day, indeed.

London man finds a mysterious egg, incubates it, and launches a Pixar-worthy journey of love

When Riyadh found an abandoned egg, he had no idea that it would change his life.

When Riyadh found an egg, he had no idea how much it would change his life.

The story of Riyadh and Spike starts like the opening to a children's book: "One day, a man was walking along and spotted a lone egg where an egg should not have been…" And between that beginning and the story's mostly sweet ending is a beautiful journey of curiosity, care, and connection that has captivated people all over the world.

Irish author Riyadh Khalaf was out walking in Devon, England, when he came upon an egg. "We just found what we think is a duck egg," Riyadh says in a video showing the milky white egg sitting in a pile of dirt. "Just sitting here on its own. No nest. No other eggs."

Thinking there was no way it was going to survive on its own, Riyadh put the egg in a paper cup cushioned with a napkin and took it home to London, which entailed two car rides, a hotel stay, a train ride, a tube ride, and a bus ride. He said he used to breed chickens and pigeons, so he had some experience with birds. Knowing the egg could survive for a while in a dormant state, he ordered an incubator on Amazon, and the journey to see if the egg was viable began.

Even though it was "just an egg," Riyadh quickly became attached, and once it showed signs of life he took on the role of "duck dad." Every day, the egg showed a drastic change in development, and Riyadh's giddy joy at each new discovery—movement, a discernible eye, a beak outline—was palpable. He devoured information on ducks to learn as much as he could about the baby he was (hopefully) about to hatch and care for.

Finally, 28 days later, the shell of the egg began to crack. "I could see this very clear outline of the most gorgeous little round bill," Riyadh said—confirmation that it was, indeed, a duck as he had suspected. But duckling hatching is a process, and one they have to do it on their own. Ducklings instinctively know to turn the egg as it hatches so that the umbilical cord detaches, and the whole process can take up to 48 hours. Riyadh watched and monitored until he finally fell asleep, but at 4:51am, 29 hours after the egg had started to hatch, he awakened to the sound of tweets.

"There was just this little wet alien staring back at me," he said. "It was love at first sight."

Riyadh named his rescue duckling Spike. Once Spike was ready to leave the incubator, he moved into "Duckingham Palace," a setup with all of the things he would need to grow into a healthy, self-sufficient duck—including things that contribute to his mental health. (Apparently ducklings can die from poor mental health, which can happen when they don't have other ducks to interact with—who knew?)

"My son shall not only survive, but he shall thrive!" declared the proud papa.

Riyadh knew it would be impossible for Spike to not imprint on him somewhat, but he didn't want him to see him as his mother. Riyadh set up mirrors so that Spike could see another duckling (even though it was just himself) and used a surrogate stuffed duck to teach him how to do things like eat food with his beak. He used a duck whistle and hid his face from Spike while feeding him, and he played duck sounds on his computer to accustom Spike to the sounds of his species.

"It's just such a fulfilling process to watch a small being learn," said Riyadh.

As Spike grew, Riyadh took him to the park to get him accustomed to the outdoors and gave him opportunities to swim in a small bath. He learned to forage and do all the things a duck needs to do. Throughout, Riyadh made sure that Spike was getting the proper balanced nutrition he needed as well. Check this out:


After 89 days, the day finally came for Spike to leave Riyadh's care and be integrated into a community of his kind "to learn how to properly be a duck." A rehabilitation center welcomed him in and he joined a flock in an open-air facility where he would be able to choose whether to stay or to leave once he became accustomed to flying. Within a few weeks of being at the rehabilitation center, his signature mallard colors developed, marking his transition from adolescence. Spike has been thriving with his flock, and Riyadh was even able to share video of his first flight.

This is the where "And they all lived happily ever after" would be a fitting end to the story, but unfortunately, Spike and his fowl friends are living in trying times. The rehabilitation center was notified by the U.K. government in December of 2024 that the duck flock needed to be kept indoors for the time being to protect them from a bird flu outbreak and keep it from spreading.

Building an entire building for a flock of ducks is not a simple or cheap task, so Riyadh called on his community of "daunties" and "duncles" who had been following Spike's story to help with a fundraiser to build a "Duckingham Palace" for the whole flock. Riyadh's followers quickly raised over £11,000, which made a huge difference for the center's owners to be able to protect Spike and his friends.

All in all, Riyadh and Spike's story is a testament to what can happen when people genuinely care. If Riyadh had left that egg where it was, it may not have made it. If Spike hadn't survived and been moved to the rehab center, the ducks there would be in greater danger of the bird flu due to the costs of building an indoor shelter for them. Despite the ongoing bird flu threat, the story really does have a happy ending.

Thank to Riyadh for sharing Spike's journey with us. (You can follow Riyadh on Instagram here.)
