It’s been nearly 40 years since killer whales off the west coast of North America were spotted wearing dead salmon on their heads. No one knows why this whacky trend began or why it ended, but we do know it’s back.
Five years ago a bottlenose dolphin strayed far from his usual habitat and ended up in the chilly waters off the Danish coast. He hung around, the locals named him Delle, and marine biologists at the University of Southern Denmark began studying the 17-year-old loner.
There are plenty of anecdotes about animals getting squiffy on fermented fruits in the wild, but we tend to think of these drunken episodes as rare and accidental. New research, which appears in Trends in Ecology & Evolution, challenges this assumption.
Humans have been kissing each other – for one reason or another – for thousands of years. Evolutionary psychologist Adriano Lameira wants to know why, so he’s been spying on our kissing cousins (other apes) to see if they offer any clues that might reveal the purpose, if any, of a good smooch.
Sphen the gentoo penguin has died in Australia, aged 11. He is mourned by his partner, Magic, along with much of the rest of the world, which had celebrated the unusual union since 2018, when the pair met and fell in love at the Sea Life Sydney Aquarium.
Spider-gazing researchers in China say that the orb-weaving spider (Araneus ventricosus) entices male fireflies into its web, then it gets freaky. Somehow the spider manipulates its prey into mimicking a female firefly’s flashing light, which lures more amorous males into the deathtrap.
The smell of human stress affects dogs’ emotions – and their decision-making – according to a study conducted by the University of Bristol, Cardiff University, and the British charity Medical Detection Dogs. Their research appears in Scientific Reports.
There is something about ginger cats. They tend to be more confident, more outgoing, and generally more cheeky – especially the toms. BBC News asked biologist and cat behavior expert Roger Tabor if there was a reason for ginger adventurousness.
The Australian animated series Bluey has pre-school fans all over the world. Plenty of adults love the show too, and so do their dogs for some reason. People magazine consulted with Amanda Farah, the National Training & Behavior Coordinator for Best Friends Animal Society, to break down why the show has become known as “dog entertainment.”
A family-friendly zoo in England has an R-rated problem: five African grey parrots that curse a blue streak. The foul-mouthed birds are spicing up the proceedings at Lincolnshire Wildlife Park in Friskney.
In August 2017, a total solar eclipse dazzled and baffled animals across much of the country. Even the US president at the time lost his head (momentarily?), and stared directly at the sun without using ocular protection.
Something funny is going on with our closest relatives – chimpanzees, bonobos, orangutans, and gorillas. Like humans, our cousins seem to revel in comedy – slapstick mainly, but comedy nonetheless. The Max Planck Institute of Animal Behavior is looking into the fun.
Researchers at the University of California, Berkeley, have found that great apes and chimpanzees can recognize mates they hadn't seen for years — in some cases for more than two decades — evidence of the longest-lasting nonhuman memory ever recorded.
When it comes to power naps, the chinstrap penguin is king. Researchers in Antarctica have determined that the species will doze off for four seconds per nap, up to 10,000 times a day. Their study appears in the journal Science.
In western Thailand just outside Kanchanaburi, an elephant sanctuary is home to a few dozen rescued domestic elephants. They’ve had a difficult time, either born into a brutal life of logging or retirees from the slightly less degrading tourism trade.
The orcas were still at it off the coast of Spain on Halloween when a small but persistent pod of the killer whales harassed a boat for a solid 45 minutes, causing enough damage to sink it.
Researchers spent many hours watching and filming domestic cats in a Los Angeles cat cafe, and they determined that the felines can conjure nearly 300 facial expressions. The research is published in the journal Behavioural Processes.
Since 2007, marine biologists and interested amateurs have been observing a curious behavior of humpback whales called “kelping,” in which the giant cetaceans seem to be playing with seaweed. Now researchers from Griffiths University in Australia have looked into the phenomenon; their study appears in the Journal of Marine Science and Engineering.
Female frogs, specifically the European common frog, deploy a number of strategies to ward off hyper-amorous males, including faking their own deaths. Researchers from the Museum für Naturkunde in Berlin publish the sex-averse findings in the journal Royal Society Open Science.
Commander, Joe Biden’s 2-year-old German shepherd, has been removed from the White House after biting a Secret Service agent, at least the eleventh such incident since Biden took office in 2021. Commander may now join Major, another biting shepherd, who was exiled to Delaware last year to live with the president’s friends.
