One of Australia’s 15 million feral cats at work on a native marsupial, the phascogale
Domestic cats have become notorious in recent years as one of the most destructive invasive species on the planet, now threatening dozens of bird and mammal species with extinction. (That’s on top of the 30 or so species they have already eradicated.) When conservationists are trying to restore a threatened species to its old habitats, a single murderous cat can be enough to destroy the entire project.
Now frustrated scientists in Australia are proposing to apply criminal forensics and even a poison pill to identify and eliminate problem cats—and possibly spare other cats that are innocent of the killing. In a new study in the journal Biological Conservation, they call these experimental techniques “predator profiling.”
A team of researchers led by ecologist Katherine Moseby at the University of Adelaide looked at restoration attempts for what they call “challenging species.” That generally means mammals that are big enough, toothy enough, or just plain mean enough that you might not think the average outdoor cat Read the rest of this entry »

My latest for Takepart:
Stare deeply into a cat’s eyes, and you’ll see the unavoidable truth: It is a sleek, stealthy, killing machine. In the United States, outdoor cats kill billions of birds, amphibians, and small mammals every year. Despite a widespread campaign by environmentalists to persuade people to keep their little killers indoors, many cat owners refuse to do so. A new product from a company called Birdsbesafe won’t entirely fix that problem, but it will help, and two scientific studies suggest that it works. It’s the sort of collar a clown would wear, with a brightly colored frill sticking out all around, making the wearer much easier to see and avoid.
Susan Willson, a Birdsbesafe customer, was hunting around on the Internet when she found the collar. She knew how deadly cats can be. It’s not just that she’s a conservation biologist specializing in birds at St. Lawrence University in Canton, New York. She’s also the owner of two outdoor cats, and one of them, “the Gorilla,” is especially adept at killing birds. “Obviously, the best thing to do is to keep your cat inside,” Willson said. But when she tried bringing the Gorilla inside, it touched off what she describes as “a peeing war” with her three indoor cats.
“At that point, we couldn’t keep him in,” she said, but euthanizing him Read the rest of this entry »

This photo is from the Epson International Pano Awards, a photo contest, and a selection of winners is appearing in the Mail Online.

Yesterday the leopard seemed to have the world by the ass. But today a leopard meets a honey badger, a quarter of its size and ten times as mean. World now has leopard by ass. Circle of Life and all that.
This sequence also comes from Botswana, by way of Dutch photograher Vincent Grafhorst. The text is from The Mail Online (Caveat: I am doubtful about the attribution of that quote to Mark Twain):
An unlucky leopard got more than it bargained for after trying to catch and eat a honey badger.
These pictures show the leopard lamenting its overconfidence when the smaller beast lived up to Mark Twain’s old adage: ‘It’s not the size of the dog in the fight, it’s the size of the fight in the dog.’
After spotting the badger from a distance, the leopard managed to rush down inside its burrow and drag it outside for what it thought was going to be an easy meal.
But despite catching its prey by the neck, the tough mammal managed to wriggle free thanks to its loose skin.

I was in the Okavango Delta recently and saw a leopard gracefully climb down a tree, at leisure.
But this photo and video sequence from the same vicinity is incredible. It’s by Yasmin Tajik of Shalimar Studios (which is–go figure–a Las Vegas wedding photo outfit; I bet they catch every punch when a cat fight breaks out on the dance floor).
First the video, then the stills, with Tajik’s narration.

Clever cormorant says, “Howdy” to alewife.
A few weeks ago I wrote about the new fish ladder bringing alewives back to Rogers Lake in Old Lyme. These devices are built mainly to help fish recover old breeding grounds blocked off long ago by dams. But the alewives aren’t the only ones to benefit. In its weekly report on fish-counter results at fish ladders around the state, the Connecticut DEEP recently included this photograph from the fishway at Bunnell Pond in Bridgeport. Something about the shadow-puppetry character of the photo makes it especially creepy. Another photo showed Read the rest of this entry »

Gopher snake schools juvenile red-tailed hawk on the streets of the city
I’ve written a few posts lately about wildlife in the city. Then, last night on Facebook, I happened to run across this strange photo, taken on December 28 in the middle of Los Angeles, not far from Dodger Stadium.
The photographer was “David A.” and this account seems to come from a friend: “It’s hard to say what a hawk was doing tangled up with a snake in the middle of Scott Avenue in Echo Park on Friday afternoon. But David A., who snapped the photo above, and a few other people watched and waited as the serpent and bird of prey were locked in a strange embrace on the pavement near Elysian Park: ‘I thought I heard one person say that they thought the hawk had been run over as it just came down with the snake in the street. It must have just grabbed it. I was there maybe five minutes. In that time, the hawk was in the position pictured and the snake was slowly freeing itself (not so much wrestling). The hawk wasn’t moving much. We stood by to make sure no cars would run them over. Once free, the hawk flew off and seemed to not be harmed. The drama ended with the snake slowly slithering back in the direction of the park,’ David said.”
One Facebook commenter suggested that, in the manner of Hollywood stars drawing unwanted attention, the hawk is saying, “No pictures, please.”
Here’s a more informed explanation by Greg Pauly of the Los Angeles County Natural History Museum.
The posting also brought out this even more spectacular photo Read the rest of this entry »

This is a deeply disturbing idea. Imagine paddling down a stream and looking up to see an alligator or crocodile looking down. Check out the press release:
When most people envision crocodiles and alligators, they think of them waddling on the ground or wading in water — not climbing trees. However, a University of Tennessee, Knoxville, study has found that the reptiles can climb trees as far as the crowns.
Vladimir Dinets, a research assistant professor in the Department of Psychology, is the first to thoroughly study the tree-climbing and -basking behavior. The research is published in the journal Herpetology.
Dinets and his colleagues observed crocodilian species on three continents — Australia, Africa and North America — and examined previous studies and anecdotal observations. They found that four species climbed trees — usually above water — but how far they ventured upward and outward varied by their sizes. The smaller crocodilians were able to climb higher and further than the larger ones. Some species were observed climbing as far as four meters high in a tree and five meters down a branch.
“Climbing a steep hill or steep branch is mechanically similar, assuming the branch is wide enough to walk on,” the authors wrote. “Still, the ability to climb vertically is a measure of crocodiles’ spectacular agility on land.”
The crocodilians seen climbing trees, whether at night or during the day, were skittish of being approached, jumping or falling into the water when an approaching observer was as far as 10 meters away. This response led the researchers to believe that the tree climbing and basking are driven by two conditions Read the rest of this entry »

This video just went up, showing what commuters saw from a ferry yesterday in British Columbia. Here’s the story from the Vancouver Sun:
An increase in transient killer whales and white-sided dolphins in the Strait of Georgia led to a rare sighting of an attack between the two mammals on Monday near Nanaimo.Travellers on board a BC Ferry were stunned as they Read the rest of this entry »
