With Alaska’s fat bears done packing on their winter weight and spooky season in full swing, it’s time to turn our collective animal-loving attention to a smaller mammal—bats. The Bureau of Land Management’s (BOEM) annual Bat Beauty Contest returns on October 24 and promises “plenty of batty puns.”

Beginning Saturday, October 24, BOEM will post photos of the competitors to their Facebook and Instagram accounts and ask you to vote for the best-looking one. All of the competing bats are part of wild populations that live on land managed by the public agency and are photographed by wildlife technicians. The winner will be announced (appropriately) on Saturday, October 31.

The bats in this competition are known for their squishy faces and clever names. In 2024, a hoary bat (Lasiurus cinereus) from Oregon named Hoary Potter took the crown. Other contestants included a long-eared myotis (Myotis evotis) named Honey Bunches of MyOtis, a myotis bat (Myotis myotis) named Robert Battinson, and western small-footed bats (Myotis ciliolabrum) named Batt Damon and Batlor Swift. The contest was not held in 2025 due to the 43-day-long federal government shutdown. 

The contest is not all bat puns and a way to keep the spirit of Fat Bear Week alive. It falls during Bat Week (October 24-31). Bat Week raises awareness about the Earth’s only flying mammal. More than just a Halloween symbol, bats play a critical ecological role as plant pollinators and through eating insects that can threaten crops and forests around the world. According to Bat Week, one bat can eat up to its body weight in insects every night. Only three species of bats eat animal blood, with two specializing in bird blood. Female lesser long-nosed bats even make tequila possible. Every spring, they migrate from south-central Mexico up to the southwestern United States, following “nectar corridors” of columnar cacti and agave plants. They pollinate agave plants, which are then used to make tequila and mezcal. When they feed on cactus fruits and nectar, they may also help disperse cacti seeds. Other bats eat pollen, nectar, or fruit.

Bats are increasingly threatened due to habitat loss, light pollution, and diseases like white-nose syndrome. This fungal disease infects the skin of the muzzle, ears, and wings of hibernating bats. In about 20 years, it has killed millions of bats across North America and affects about half of the species on the continent. Bats also are often misunderstood as carriers of diseases such as rabies. 

The planet is home to over 1,400 species of bats, and they make up almost 20 percent of all mammal species. Bats also can be found almost everywhere on Earth, even in desert and polar regions. To look up which bat species live near you, you can use Bat Week’s state bat database.

Stay tuned for more Bat Week updates!

Realized green hydrogen demand lags behind policy targets but could be accelerated by accounting for spatial spillovers, which refer to demand-side interdependencies where adoption by one user encourages further adoption by nearby users. Revising EU green hydrogen policies, including Hydrogen Valleys and European Hydrogen Bank auctions, to better account for these location-specific demand-side patterns could improve their effectiveness.

EU green hydrogen policies could be more effective if they accounted for spatial spillovers. These spillovers are a primary driver of diffusion, and spatially informed demand-side policies could improve cost-effectiveness by up to 41%.

October is officially Bat Appreciation Month. In the spirit of the season and conservation, a team of biologists in California recently spent time finding bats at Muir Woods National Monument and Samuel P. Taylor State Park. And while Halloween is fast approaching, the activity had nothing to do with spooky festivities and everything to do with tracking hoary (Lasiurus cinereus) and western red bats (Lasiurus blossevillii). 

The goal of their survey was to put GPS trackers on bats from the two migratory species. Hoary bats have grey-white fur and are the most widespread bat species in North, Central, and South America. Western red bats, also known as southern red bats, sport a reddish fur and are found in parts of South America. In redwood forests, bats like nesting within holes inside large trees. 

“When they migrate, those little guys can cover a LOT of ground!” the Golden Gate National Recreation Area writes, referencing both species. “By learning about these migratory patterns, we can better understand entire ecosystems like Muir Woods.”

Bats are important members of such ecosystems. They are pollinators, they spread seeds, and they help manage insect populations. To catch these helpful agents, scientists set up a sheer, delicate net called a “mist net” over a creek at dusk. All bats are nocturnal, and when they went searching for their next meal—bugs—they flew into the net. 

It was a bit of a trick for the winged mammals, but a treat for the human team. “Expert bat wranglers” carefully took them out of the nets, noted their weight and size, presumably attached the GPS tracker, and then returned them to the wild. 

The Golden Gate National Recreation Area’s shared pictures of tiny, disgruntled looking bats carefully pinched between gloved fingers. In one image, an expert holds a bat wing up to the light of a colleague’s headlamp. In fact, illuminated wing membrane patterns literally shed light on the bat’s age and developmental stage.

While this survey focused on two bat species, researchers at the Muir Woods National Monument have previously spotted 10 different species.

On the evening of March 18, as it was growing dark, I went to the window, not knowing what was drawing me. Next to the house stood a shadow, ghost-like, shrunken, at one with the dusk, almost translucent, and I recognized The Girl with the Broken Foot.

I walked out into the falling wet snow, slowly approaching her, and she allowed me to come close. Nine months old, she was the size of a fawn half that age. Starkly emaciated, her body seemed to be collapsing inward, her head held low. Literal hunger and a deeper starvation were palpable. She bore the haunted look of terminal solitude seen in souls driven to the margins of society, among the liv-ing, yet apart. She seemed so frail that I couldn’t imagine she would live more than another day or two.

Going inside and returning with a bowl of apples, I cut them into pieces and placed a few on the ground between us. She was raven-ously hungry and I gave her a few more apples, and still more, until she had eaten a total of eight. After she had finished eating, she stayed with me. We stood about a foot apart. She showed no fear of me, a fact which I would later come to recognize as meaningful. The moment had the compelling quality which has been present at the onset of many enduring connections in my life, of being un-bound by linear time.

“I am watching over you,” I said softly. “If you come here, I will take care of you. You are not alone.”

It was fully dark when we parted, having been together for an hour. I expected that she would recede into the woods, yet the next morning she was sleeping against the house, directly beneath the window closest to where I sit all day to work. Save for the wall separating us, she could not have gotten any closer to me.

When I went around to the front of the house, she struggled to her feet and approached. In the morning light, I was better able to assess the state of her health. Months of solitary survival had taken a severe toll. Her body seemed hollowed, her ribs and pelvis sharply visible beneath her skin, and it felt a miracle that she was alive. On her right flank was a hemispherical mass the size of a cantaloupe, which I took to be a tumor, yet it had an open, running wound at its center, which she periodically craned her neck to lick. Her eyes were running and had congealed masses at their inner corners.

I bent to get a look at her injured foot. From not being walked on, the backward-facing cloven hoof had grown to an abnormal length and was curling upward. The wrist, which unnaturally bore her weight, had a flattened forward surface, an oval about two inches across, worn raw, without hair or skin, only pale pink–grey flesh, which, at its center, appeared to have been further abraded to the bone. Her right front foot, forced to compensate, was splayed and rockered, her right scapula protruded, and her front quarters were substantially lower than her hips.

I again placed apple pieces on the ground between us. I spoke very gently to her, saying, “You are the best one of all the deer. You are the most beautiful. You are good.” I continued to talk to her while she ate her apples, and when she had taken all she could, she returned to her resting spot under the window. I went inside to work, keeping periodic watch, pleased that she seemed to have claimed a place. But in a few minutes, from around the corner of the house came the twins, followed by their mother who immediately and ag-gressively charged at her. The Girl with the Broken Foot lurched upright and hobbled down the embankment, across the road and into the woods.

She was once again alone, but a step had been taken. Since the previous evening, things had changed. Even before her second feed-ing she had recognized me on sight. She had approached and had again allowed me near.

Although I had seen her fewer than half a dozen times in the preceding months, from the night of our first connection, she began to come to the house every day. She slowly gained strength and I would watch for her and thrill to the sight of her slow approach. It was our private time. We stood together, and I placed her food on the ground between us. After she ate, she would stare into my eyes for long periods, seemingly entranced. I told her stories. I sang softly to her. I told her she was my beauty.

So began our journey, and one of the greatest loves I have ever known.

One cold December day in 2021, Colorado carnivorous plant grower Jeremiah Harris shared some pictures of wild Amazonian giant water lilies (Victoria amazonica) plants in the Inírida River in Guainía, Colombia to Instagram. There’s just one problem. No known Victoria water lily species grow there. 

When water lily expert Carlos Magdalena saw the post on Instagram, he suspected a new plant species could be involved. To investigate the matter, he used satellite imagery to remotely search the Inírida River and its surrounding lakes and confirmed the presence of Victorias.

And yes, you can see these enormous plants from space. Victorias grow the world’s second largest single plant leaf. 

Magdalena is a botanical and scientific research horticulturist at the Royal Botanic Gardens, Kew in the U.K. Along with his colleagues, the team went on a five-day expedition to Inírida. The team included members of the Indigenous reserves del río Atabapo, one of whom had seen the lilies during his childhood. 

However, the trip didn’t exactly go according to plan. By their last night, they had found only two water lily plants, neither of which had flowers. This was a problem, because botanists need a flower to differentiate species. As if that wasn’t bad enough, the water lilies they found seemed to be struggling with a late rainy season. 

But when Magdalena described their situation to the expedition’s boat captain, Gustavo Melo, he said he knew where they could find more of this water lily. They didn’t have much time to do so, with the team’s flight back to Bogotá was at 9:00 a.m. the next morning. Thus at 1:00 a.m., Melo, a member of the Indigenous Tucano community, led them to a small lake. There, they found five more Victorias, one of which was blooming. 

“This is one of those extraordinary stories where indigenous and horticultural knowledge with the help of social media and technology came together to uncover a truly extraordinary botanical achievement,” Magdalena said in a statement. 

The  researchers were able to collect what they needed to start the official scientific description of the new species: Victoria colombiana. They even managed to make that early flight. In their recent study published in the journal Phytotaxa, he and his colleagues also announced the discovery of another new Victoria species, Victoria mattogrossensis. 

The team estimates that there are only between 30 and 50 wild V. colombiana plants, and is extremely vulnerable to extinction. They are currently working to get the plant officially categorized as Critically Endangered by the IUCN Red List. 

“Now that we know this water lily exists, our responsibility is to understand it better and protect it. With so many plants in the wild threatened with extinction, we simply cannot wait any longer to take action,” Magdalena added. Experts are considering starting a naturalized population in a more accessible lake in Indigenous territory and researchers also are hoping to cultivate the species in Bogotà.
