No, the pack is led by the alpha (breeding) females. The picture is taken from the BBC 2011 documentary Frozen Planet. This Guardian article which features pictures from the documentary describes the picture as: A massive pack of 25 timberwolves hunting bison on the Arctic circle in northern Canada. In mid-winter in Wood Buffalo National Park ...

There is no suggestion from the original photographers that spiders place water droplets on their heads. Web pages that re-post these photos don't have any references to support the notion. There are at least two photographers who stage these photographs. Consider Dmitriy Yoav Reinshtein whose gallery includes mantis with water droplet "hat" housefly ...

This is a myth, because monkeys don't normally eat bananas in the wild. "The entire wild monkey-banana connection in fact is total fabrication," Katharine Milton, who has studied the diets of primates for decades, told Tech Insider. "The edible banana is a cultivated domesticated plant and fruit. Wild monkeys never encounter bananas at all ever unless ...

Yes, they do share... but not specifically because of the fires or out of a sense of altruism. According to AFP Fact Check: University of Adelaide ecologist Dr. Michael Swinbourne told AFP via email on January 16, 2020: “Wombats will share their burrows with other animals at the same time. I wouldn't say that wombats are "happy" about sharing with other ...

The first claim in your article The authors estimate they are responsible for the deaths of between 1.4 and 3.7 billion birds and 6.9-20.7 billion mammals annually comes from this article (full-text), where the authors state (table 2) that domestic cats are responsible for the deaths of 1.4-3.7 billion bird deaths and a much larger number of mammal ...

In the "Emerging Infectious Diseases Journal" issued by the CDC, there is a report of a trial that involved one pinyon mouse (P. truei) and 19 deer mice (Peromyscus maniculatus). The trial apparently demonstrated that when removed from the location of the infestation and dislocated at to different distances ranging between 50m and 1200m (0.03 miles ...

There is not enough scientific data to prove suicidal behavior in non-human animals. Naturalists have not identified suicide in nonhuman species in field situations, despite intensive study of thousands of animal species. ... Few empirical investigations have been carried out on this topic [1]. Modern naturalistic studies have found little evidence of self-...

About Rob Pilley, the "zoologist and producer" who gave the Daily news their original quotes. A google scholar search does not turn up any research from him; none of the 120 papers by a R Pilley are zoological in nature. Most of them are probably by other people. He does have a decent list of credits on IMDB. This suggests that he is an expert on making ...

Yes, some monkeys do peel bananas from the floral end, if they get access to them, but not all the time. While Sklivvz's answer is correct about the lack of access of monkeys to bananas in the wild, monkeys who live next to humans have access to bananas, and, at least some of them, do peel the banana from the floral side. Here are some videos depicting ...

According to The Lady and Her Tiger, the autobiography of animal trainer and animal rights advocate Pat Derby, at page 75: I remember one occasion when a television commercial was being filmed with a lion and a young model. The manager made a point of asking the girl whether she were menstruating; as it happened, she was, but she wanted the job and said ...

No. Quoting from Homosexual Behaviour in Animals: An Evolutionary Perspective [page 28] When male Japanese macaques do exhibit an interest in homosexual consortships, female partners will sometimes threaten or attack them and attempt to drive the males away.

It mentions there have been 22 births in that year, a low birth rate considering ...

The way most Japanese fishing companies actually do this is a process called Ikejime. There are a few different ways to do this but they are all basically the same cause brain death and/or paralysis in the fish in a specific way, in order to keep the fish fresh. Kaimin Katsugyo which uses acupuncture to keep fish alive but docile, this seems to be much ...

The claim is plausible. Let's break it down into several components: Q: Are monkeys capable of stealing wallets or learning to use vending machines? A: Certainly. There is ample video evidence of monkeys stealing wallets and using vending machines. Token-based food vending is common practice in studies of animal behavior. Q: Are simians capable of ...

Evidence: The concept of alpha wolf in wolf packs was based on studies on captive wolves. Most research on the social dynamics of wolf packs, however, has been conducted on wolves in captivity. These captive packs were usually composed of an assortment of wolves from various sources placed together and allowed to breed at will (Schenkel 1947; Rabb et al. ...

Barks are one of the way in which dogs communicate. For example, some barks mean loneliness and can be methodically distinguished from other kinds. Our experiment showed that dogs can perceive the difference between barks originating from different situations, thus barking is perhaps a communicative tool not only for dogs to humans, but for dogs to dogs ...

Some animals tend to give specific calls when they discover food or detect particular types of predators. Companions of those animals tend to respond with food searching behavior or adopt some appropriate escape responses and those response signals seem to denote objects in the environment. Per research mentioned below, it can be seen that male rooster (...

Where did this story originate? Is that source reputable? Here's the BBC's version of it: Kidnapped girl 'rescued' by lions Sergeant Wondmu Wedaj told the media from Bita Genet, some 560 kilometres (348 miles) south-west of the capital, Addis Ababa, that they found the girl alive but shocked and terrified. To be honest it doesn't say that the lions ...

The Pacific Standard magazine published a critical look at this claim which is available for free on the web. It says the original study started in 2005 and may have received some attention while it was still in progress, but wasn't formally published until 2011. I believe it was published in German, but I cannot find a working link to it. It seems to have ...

Summary: We don't have good evidence that let's us conclude precisely what Rambo's "reading" abilities are. The experimental design and setup in the video does not allow to judge this, and there isn't that much more material on amount Rambo's "reading" abilities publicly available. In general, dogs can be trained to distinguish visual ...

Their monogamy does seem to be a well-established claim but not that they never form another pair-bond: The source you quote doesn't support St Jerome's claim. So you could probably drop "and never remarry" part of the question title. Pigeons are monogamous; i.e., they mate for life, and the survivor accepts a new mate only slowly. Encyclopedia ...

It's hard to find reputable sources on this issue, but let me present the two different takes on it that I found. According to this article: Cockroaches, apparently, have bulky bodies (composing of 3 heavy body segments) which are only supported by 6 long thin legs, As they die, they lose muscle-control causing the leg muscles to contract. As a ...

According to Cooperative Predation by Coyotes on Badgers Journal of Mammalogy, Volume 61, Issue 2, 20 May 1980, Pages 375–376: Although badgers occasionally kill and eat coyote pups (Young, 1951), to our knowledge there is no previous report of coyotes preying on badgers. So this article is saying that it is the first report of a coyote eating a badger,...

I didn't find any systematic studies of wildlife digging up toilet paper (TP), but there is one which found that TP buried under rocks doesn't degrade fast enough, even in presence of feces (simulant, in this study). An examination of the relative breakdown rates of unused toilet paper, facial tissues and tampons was undertaken in nine different ...

I think the answer is really in the physics of the cockroach, or other insect bodies. When the insect dies, rigor mortis sets in. Since the flexor muscles are almost always larger than the extensor muscles, the contraction causes the legs to bend inwards into the crossed position. The bug pulled into a cylindrical shape by rigor is now unstable, and is ...

In Neurobiology of Chemical Communication., Chapter 5 - Chemical Communication in the Honey Bee Society, Section 5.1.2.5 Defensive Behavior: Alarm Pheromones details how trigger pheromones are released with the extrusion of the stinger whether or not an actual stinging has taken place. So, an angry bee is a signaling bee. Also, it seems a fair assumption ...
