CONGERS, N.Y. — Of all the coyotes that roam Dr. Davies Farm, looking for prey on this apple-picking orchard less than an hour from New York City, manager James Higgins says one of the pack stands out: Bigger and with more gray fur than its mates, this wolflike canine is a reason, Mr. Higgins says, there are fewer deer nibbling at Dr. Davies’s stock.
“We love having him here,” Mr. Higgins said as he drove around the property on an ad hoc coyote safari. There were no sightings, but Mr. Higgins ventured a profile of the creature: aloof, calm, uninterested in people.
“Anytime he sees any kind of human activity, he bolts,” Mr. Higgins said. “As long as he stays in his space and we stay in ours, everyone works in harmony.” Continue reading
The birders among us say thank you, Noah Comet (and to the New York Times for providing the valuable real estate for this informative, charming essay):
ANNAPOLIS, Md. — Owls tend to be secretive. While there are a few American species that enjoy the daylight hours, most are nocturnal and spend their days behind thick greenery or uncannily blending into the bark of the trees they nestle against. Once they’ve found a secure place to snooze, they are likely to return to that spot daily, but even if you find evidence of their presence — scat and regurgitated pellets — good luck seeing the clandestine culprits.
I’m a seasoned birder with a particular interest in owls, and on my ventures to find them, even when I have specific information on where they’ve been seen just minutes before, I’ve failed to find them more often than not. Such elusiveness makes “owling” one of the great birding challenges. Being the first to find a particular owl is regarded by some as a badge of distinction, and those who find them regularly are viewed with awe-struck reverence. Continue reading
Members of our team have long been fans of bees and all bird species, with a particular soft spot for hummingbirds in particular. With their gemlike plumage and engaging personality, what’s not to love?
What’s small, buzzes here and there and visits flowers?
If you said bees or hummingbirds, you got it. And you wouldn’t be the first if you mixed the two up. In Medieval Europe, some called bees the smallest birds. In Chinese and Japanese, the words for hummingbird translate into “bee bird.” Today we call the smallest hummingbird — weighing less than a penny and only a bit larger than the biggest bee — the bee hummingbird.
And now a group of researchers say we should embrace our history of lumping the two together. The way scientists study bees could help them study hummingbird behavior, too, they argue in a review published Tuesday in Biology Letters. Continue reading
Conservationists have been sounding the alarm over invasive species for years, warning of the damage they can cause to habitats and native animals. But in Florida, an invasive snail might be helping an endangered bird species come back from the brink, researchers say.
The population of North American snail kites — birds that use curved beaks and long claws to dine on small apple snails in the Florida Everglades — had been dwindling for years, from 3,500 in 2000 to just 700 in 2007. Things began to look particularly bleak in 2004, when a portion of the Everglades was invaded by a species of larger snail that the birds had historically struggled to eat. Ornithologists assumed the shift would hasten the snail kite’s decline. Continue reading
Thanks to Ed Yong and his editors at The Atlantic for this story on one country’s approach to rats:
The nation wants to eradicate all invasive mammal predators by 2050. Gene-editing technology could help—or it could trigger an ecological disaster of global proportions.
The first thing that hit me about Zealandia was the noise.
I was a 15-minute drive from the center of Wellington, New Zealand’s capital city, but instead of the honks of horns or the bustle of passersby, all I could hear was birdsong. It came in every flavor—resonant coos, high-pitched cheeps, and alien notes that seemed to come from otherworldly instruments. Continue reading
Yesterday’s topic touched on a taboo of sorts, but in the interest of furthering our understanding of one of the most remarkable organisms on the planet; today, likewise, thanks to Steph Yin for her note on creatures sometimes considered creepy but whose environmental services are remarkably valuable:
I was raised by grandparents who spoke only Mandarin, so I did not speak English until I went to preschool in Philadelphia. There, guided by English-speaking teachers and surrounded by toddlers babbling in loose English, I adopted the new language quickly.
Young bats may not be so different. Continue reading
A fascinating story appears in the Science section of the New York Times this week. It is a reminder of the progress made over the last century in cleaning up the air in North America. Birds are key to the evidential trail in telling the story. The title is one of the most unappealing we have seen in ages, but science is not all sweetness and light:
Tucked away in the drawers of natural history museums across America’s Rust Belt, thousands of dead birds carry dirty secrets from America’s polluted past.
The specimens that were put away around the start of the 20th century are far grimier than the ones from more recent decades. And now, climate scientists and historians can thank museum curators for not having tidied them up before storing them. Continue reading
This feature story suggests that even as we stress nature on a global scale, there are creative scientists working on fixes for particular challenges:
As reefs die off, researchers want to breed the world’s hardiest corals in labs and return them to the sea to multiply. The effort raises scientific and ethical questions. Continue reading
Thanks to Jonathon Shaw and Harvard Magazine for bringing our attention to this book:
The microbial earth, brought into view
IN ROCKS AND SOIL, air, ponds and oceans, life is dominated by creatures that humans cannot see. Microbes thrive everywhere, from gardens and kitchens to the harshest environments on the planet: under polar ice, in hydrothermal vents at the bottom of the sea, in hot springs that spew acid. A single gram of soil teems with billions of them, and their genetic diversity is equally impressive, dwarfing that of all the plants and animals on Earth. Life at the Edge of Sight: A Photographic Exploration of the Microbial World (forthcoming from The Belknap Press of Harvard University Press), brings the planet-shaping diversity of these single-celled, microscopic organisms into view through stunning images. Co-authors Roberto Kolter, professor of microbiology and immunology, and Scott Chimileski, a research fellow in microbiology and immunology at Harvard Medical School, share their passion for the subject in part by magnifying what cannot be seen unaided, in part by revealing large-scale microbial impacts on the landscape. Kolter has long been a leader in microbial science at Harvard, while Chimileski brings to his scholarship a talent for landscape, macro, and technical photography…
Read the whole article here, and if you happen to be in Cambridge (MA, USA) this exhibition might be of interest:
The minuscule ecosystem within a single drop of water is home to an astonishing diversity of organisms busily living out their lives and interconnected by myriad complex relationships. The photographic exhibit World in a Drop is an aesthetic journey into this microbial world, as revealed through cutting-edge imaging technologies. With expertly executed photography, videography, and poetic narration, Scott Chimileski and Roberto Kolter capture the intrinsic beauty of a mysterious world that is seldom recognized.
Thanks to Carolyn Beans and the salt colleagues at National Public Radio (USA) for this:
The parrots of Southeastern Peru crave an earthy delicacy: dirt. At the Colorado clay lick, a cliff face rising above the Tambopata River in the western Amazon Basin, parrots — often hundreds at a time from up to 18 species — gather each day to feast on sun-hardened clay. Continue reading
Once again eBird data and the Cornell Lab of Ornithology studies highlight the importance of forest conservation for species survival, as seen in Climate Change Or Habitat Loss? Study Weighs Future Priorities For Conserving Forest Migrants:
Birds are among the first to let us know when the environment is out of whack. But predicting what might happen to bird populations is tricky. Studies often focus on a single issue or location: breeding grounds or wintering grounds, changes in climate, loss of habitat. But in the real world, nothing occurs in isolation. A new study just published in the journal Global Change Biology pulls the pieces together. Continue reading
Thanks to Brent Crane writing in the Elements section of the New Yorker’s website:
Five years ago, George Heimpel, an entomologist at the University of Minnesota, travelled to Trinidad in search of insect larvae. He was after several kinds in particular—Philornis downsi, a fly whose parasitic young feed on the hatchlings of tropical birds, and various minuscule wasp species whose own offspring feed on those of the fly. Continue reading
Mention Alaska, and we are in. Wolves, ditto. An academic publication called Wildlife Monographs? You had us at Alaska and wolves:
Within the 2.5 million acres of the Yukon-Charley Rivers National Preserve in central Alaska, wolves and other majestic animals are protected. But animals like wolves do not respect lines drawn on a map. And a recent study suggests that efforts to limit populations of these predators outside those borders is having negative effects on wolves living within the preserve. Continue reading
Thanks again to the New York Times for highlighting the global nature of this scientific “call to arms” to save not only data, but genetic and organic material as a back-up plan for future generations. From the Svalbard Global Seed bank in Norway, to sperm banks for coral, endangered wildlife, and even glacial ice – these archives are meant to provide both a life line to the future and answers about the past.
The fragility of each project is evident as Science itself has come under attack from current public policy, which doesn’t appear to see the irony of their denial in the face of facts about climate change.
It was a freakishly warm evening last October when a maintenance worker first discovered the water — torrents of it, rushing into the entrance tunnel of the Svalbard Global Seed Vault, a storage facility dug some 400 feet into the side of a mountain on a Norwegian island near the North Pole. A storm was dumping rain at a time of year when the temperature was usually well below freezing; because the water had short-circuited the electrical system, the electric pumps on site were useless. This subterranean safe house holds more than 5,000 species of essential food crops, including hundreds of thousands of varieties of wheat and rice. It was supposed to be an impenetrable, modern-day Noah’s ark for plants, a life raft against climate change and catastrophe.
A few Norwegian radio stations and newspapers reported the incident at the time, but it received little international attention until May, when it was becoming clear that President Trump was likely to pull the United States out of the Paris climate agreement. Suddenly the tidings from Svalbard were everywhere, in multiple languages, with headlines like “World’s ‘Doomsday’ Seed Vault Has Been Breached by Climate Change.” It didn’t matter that the flood happened seven months earlier, or that the seeds remained safe and dry. We had just lived through the third consecutive year of the highest global temperatures on record and the lowest levels of Arctic ice; vast swaths of permafrost were melting; scientists had recently announced that some 60 percent of primate species were threatened with extinction. All these facts felt like signposts to an increasingly hopeless future for the planet. And now, here was a minifable suggesting that our attempts to preserve even mere traces of the bounty around us might fall apart, too.
Thanks to Thomas McNamee for his opinion on these matters:
In March 2016, the United States Fish and Wildlife Service proposed removing the Yellowstone grizzly bear population from the list of threatened species. The uproar was ferocious. Conservationists, scientists, 125 Indian tribes and some 650,000 citizens expressed concern about the move.
The more time we spend at Chan Chich Lodge the more we see the seasonality of birth patterns in the wild. There clearly seems to be a “baby season”, that starts with the cats and moves down the food chain to their mammalian prey, as well as birds. Although no photo captures, several jaguar cubs were sighted earlier in the year, followed by dozens of fawns and baby collared peccary. Even the Gallon Jug Farm has welcomed 4 baby horses to the fold, with a fifth on the way…but we’ll talk about that another day.
This unusual news from Panthera.org, an important Big Cat Conservation NGO who uses our 30,000 acres as part of their Jaguar Corridor research, perhaps makes a little bit of sense within the context of those patterns.
We thank Susie Weller Sheppard for sharing these field notes.
Earlier this week, Panthera President and Chief Conservation Officer Dr. Luke Hunter received photos from our partners at KopeLion with some astonishing content: the first-ever evidence of a wild lioness nursing a leopard cub.
Taken on Tuesday by a Ndutu Lodge guest in Tanzania’s Ngorongoro Conservation Area, the images show a 5-year-old lioness, known locally as ‘Nosikitok,’ suckling a leopard cub estimated to be just 3 weeks old. Continue reading
Camera traps, in the interest of science, and of conservation, are no longer a novelty. The story accompanying the photo above is new, for us. At first glance it looks like an act of aggression, which the history of whaling has taught us to expect. But this story has a much better outcome than the old obsessions:
This is how you put a video camera on a whale.
Hop into an inflatable boat and head out to where they’re feeding. Stand in a pulpit with a 20-some-foot pole in your hands. Then watch and wait until you spot a whale. Plan your angle of approach with the driver of the boat. (Never approach directly from behind). Get close. Get closer. Get within 16 feet of this sea giant — which is more than twice the size of your boat if it’s a humpback — and as soon as it surfaces, tap the whale on its wet tire of a back with the pole. If you’re lucky, the detachable suction-cup on the end of the pole — which has a camera and sensors — will stick. Continue reading
