Welcome to my blog.
Researchers have observed that the female southern pied babbler, a small black-and-white bird found across the southern African savannah, gets less smart as it ages, a correlation tied to the number of chicks she has over the years.
A female zebra shark at Chicago's Shedd Aquarium brought some pups into the world by virgin birth, according to a new study appearing in the Journal of Fish Biology. It took a few years for the aquarium researchers to realize the shark had produced offspring via parthenogenesis, in which an egg develops into a viable embryo without the hassle of sperm fertilization.
There are only a few hundred pink iguanas on Earth, and all of them live on the slopes of Wolf Volcano in the Galápagos. Now rangers from the Galápagos Conservancy and national park have spotted nesting sites and hatchlings of this critically endangered species for the first time.
New York Governor Kathy Hochul has just signed legislation that will ban the sale of dogs, cats, and rabbits at retail pet shops throughout the state, a move intended to end the inhumane conditions rampant in the commercial breeder industry. The ban kicks in December 2024.
Researchers at the University of Adelaide have at long last discovered the female snake clitoris, which was long believed to not exist. The findings are published in the Proceedings of the Royal Society B.
When the Johnston-Grimes Metropolitan Fire Department responded to an alarm last week in Grimes, Iowa, they had nothing to do because there was no fire. A security camera revealed who had pulled the alarm.
The US House passed the Big Cat Public Safety Act in July, and last week the Senate gave its blessing for the legislation via unanimous consent. Now the bill waits for Joe Biden to sign it into law before we are all old and gray.
Since 2018, Elon Musk's medical-device company Neuralink has killed about 1,500 animals – monkeys, pigs, and sheep – in its attempt to develop a brain-computer interface. Now the US Department of Agriculture is investigating the company for possible animal-welfare violations.
Winners of this year’s Comedy Wildlife Photography Awards are in and we think they are in fact funny. The comic possibilities of wildlife tend to fall into set categories. There are the photos of slapstick in progress – a 3-month-old lion cub falling out of a tree, for example, which happens to be this year’s overall winner. “It was probably his first time in a tree and his descent didn't go so well,” said photographer Jennifer Hadley.
After more than two decades of incarceration in an Albanian restaurant, Mark the bear has been freed. The animal welfare group Four Paws negotiated the release of the last so-called “restaurant bear” in Albania, and he is now on his way to a bear sanctuary in Arbesbach, Austria.
For decades kids and their families have flocked to Griffith Park Pony Rides of Los Angeles without knowing they have engaged in animal torture. But the fun ends on December 21. Badgered by animal rights zealots, the city’s elders have ordered the park to shut – just in time for the holidays!
Animals that organize in social groups occasionally experience friction, as when competing for food, living space, mates. When conflicts arise between two group members, a third-party intervention can smooth things over to the benefit of all. Pigs appear to be pretty good at conflict mediation.
A lot of people in Utah are reporting wildlife sightings, especially of cougars that stray into town. The state’s Division of Wildlife Resources is getting so many calls that this week it asked everyone to relax: you needn’t report it every time you see a big cat.
Evolutionary biologists have something called the “island rule,” which posits that organisms that evolve on islands will, over time, become smaller than their mainland counterparts. A new dwarf dinosaur species discovered in western Romania – which long, long ago featured tropical islands – supports the theory.
We’ve known for some time that the Toxoplasma gondii parasite can infect the brains of rodents, forcing them via mind control into fatal encounters with predators. Now scientists have observed that wolves infected with T. gondii are also altering their behavior, in their case by taking more risks.
Turkeys don’t stand a chance this time of year, but one flock of gobblers is taking back what’s theirs (America) starting with one New England town. The human inhabitants of Woburn, Massachusetts, population 41,000, have been under attack by an obnoxious group of five wild turkeys, a thuggish gang led by a tom named Kevin.
The white ibis has a bad rap in Australia, where it is called “bin chicken” for its propensity to root through garbage. (Also “tip turkey,” “dumpster chook,” and “rubbish raptor.”) Now the bird is winning over its critics because it has developed a particular skill set: draining the hated cane toad of its poison.
The situation is going from bad to worse for Florida’s shrinking manatee population: the gentle aquatic mammals are dying by the hundreds, mostly from starvation. A coalition of conservation groups are now petitioning the U.S. Fish and Wildlife Service to list the manatee as an endangered species, as it once was, with the hope of improving the creature’s habitat.
