Big-Balled Males Kill Infants More than the Less Endowed

Large testicles are associated with males of a given species killing youngsters. Big-balled males kill infants more than the less endowed. A recent essay in New Scientist magazine begins, "GREAT balls of fury. Large testicles could be a giveaway sign that the males of a species are given to killing their rivals' offspring." They kill so that they can then reproduce.

"Animal Weapons" and "Why Life Matters," Two Excellent Books

Two new books deserve a wide readership. In "Animal Weapons" researcher Douglas Emlen concludes, "Weapons of mass destruction change the stakes … We're not likely to survive another arms race." In "Why Life Matters" Michael Tobias and Jane Gray Morrison provide a global view of what numerous people are doing to keep diverse ecosystems and all animals alive and thriving.

The Last Great Wild Places: Rewilding Through Photographs

A new book by world renowned photographer Thomas Mangelsen called "The Last Great Wild Places" is a most welcomed volume of awe-inspiring photographs and a reminder of just how influential we have been in destroying landscapes globally. It surely will serve to rewild ourselves and also can be a valuable lesson in anthrozoology, the study of human-animal relationships.

Wolves: Hunting Affects Stress, Reproduction, and Sociality

Hunted wolves show elevated levels of stress and reproductive hormones that influence reproduction (more multiple litters in a pack) and social organization. Wolf expert Paul Paquet notes the "resulting harm can be acute, chronic, and permanent, sometimes spanning generations.” Merely counting wolves and then deciding how to manage them is a shoddy unscientific practice.

Is Going to a Zoo Like Shopping for a Car? Musical Semen

At a recent meeting of the Performing Animal Welfare Society (PAWS) many different issues were discussed, including the effects on animals being shipped around as breeding machines (musical semen), the formation of captive groups and the removal of animals for various reasons, and what zoos really do in terms of education and conservation.

Holly Bites Cesar: When You Hit a Dog There's a Price to Pay

I recently received a video of Holly, a dog, being hit -- cuffed in the neck -- by, and later biting, Cesar Millan, as he moves closer to her. It's rare to see such confrontations and I highly recommend those who want to see what happened to study this video closely. There are many lessons here in dog body language -- canid ethology -- and for respecting what a dog needs.

Animal Heroes: "Daisy to the Rescue" Celebrates Compassion

A new book about animal heroes called Daisy to the Rescue: True Stories of Daring Dogs, Paramedic Parrots, and Other Animal Heroes contains numerous stories of compassion and caring in a wide variety of animals. It is a very inspiring read and can be used to generate further studies into the study of animal consciousness and animal minds in the field of cognitive ethology.

SeaWorld Exposed: Behavioral Profiles of Captive Orcas

The information in this file of behavior profiles of captive orcas released by SeaWorld needs to be analyzed and is perfect for theses. I want to inform a wide public about these data as they are a goldmine for studying the behavioral profiles of captive orcas, many of whom are extremely aggressive and understandably go crazy in captivity. It's a study in "orcazoology."

The Emotional Lives of Cows: Ears Tell Us They're Feeling OK

A new study of the emotional lives of dairy cows shows that relaxed ear position is an indicator of positive emotions and can be used to assess an individual's well-being. We owe it to these and other animals to give them the very best lives we can. And, often, it's easy to assess what they're feeling and we must use this information on their behalf.

Killing Barred Owls to Save Spotted Owls? Problems From Hell

"There Will Be Blood" is a very important read. Its author notes, "The pressure to reach for a gun to help save one animal from another is stronger than ever. And it has triggered a conservation problem from hell." Does there really have to be blood? Some experts say "No," whereas others say "Yes." Historically conservation has been a bloody affair. But times are changing.

Rewilding: A Cultural Meme for Rehabilitating Our Hearts

My new book "Rewilding Our Hearts" calls for a personal/spiritual transformation of our relationships with all beings and their homes. In a video interview I recount how rewilding is necessary to undo the unwilding that occurs in all of our lives. Rewilding is a cultural meme and is all about rehabilitating our hearts and souls. It is about acting from the inside out.

Keeping Dogs with Special Needs Happy, Healthy, and Active

A new book called "No Walks? No Worries!" is a wonderful guide for dogs on restricted exercise. Written by Sian Ryan, who has a degree in clinical animal behavior, and Helen Zulch, a veterinarian, this book will be useful to the countless people who, from time to time, have to enrich their dog's life when she or he isn't allowed to frolic or take much exercise.

Dogs at Play: What They Do, Know, Think, and Feel

A beautifully illustrated and well referenced book called "Canine Play Behavior" by German dog trainer Mechtild Käufer is a thorough and current review of what dogs do, know, think, and feel when they play and why they do it. It also is a goldmine for future research and exposes readers to studies about which they were unaware or published in languages they cannot read.

Animals in the Media: Guidelines for Accurate Representation

Important guidelines for giving voice to the voiceless are now available. At the website "Animals and Media" you'll find a style guide for how animals should be represented in journalism, advertising, PR, and entertainment, and there are also extremely valuable resources. This website should be mandatory reading for anyone reporting about nonhuman animals. It is that good.

Rats vs. Mice in Research: Were We "More Humane" Years Ago?

Why do researchers and the federal Animal Welfare Act continue to ignore what science has told us about animal sentience? A recent research report that shows that rats and mice perform similarly in different cognitive tasks totally ignores the ethics of their use in invasive research although we know that they and other animals are highly emotional and sentient beings.

Does Your Dog Really Love You? Canine Cognition and Emotions

In this short video you will view some of the latest research on dog behavior. In this crash course you'll learn about Dr. John Pilley's renowned Border collie, Chaser, who knows the name of more than 1000 objects, Dr. Brian Hare's research on dog cognition, and Dr. Gergory Berns' use of neuroimaging to study what's going on in a dog's brain. It's a great family show.

War Dogs: Would You Send Your Dog to Fight Our Battles?

A new and well-done book by Rebecca Frankel called "War Dogs: Tales of Canine Heroism, History, and Love" tells many stories -- the ups and the downs -- of war dogs and their handlers, and supports their use to fight our battles. It is a very important and deeply troubling book that highlights our complex and paradoxical relationships with dogs and other animals.

The Emotional Lives of Animals; Children and Animal Minds

A new book by developmental psychologist William Crain titled "The Emotional Lives of Animals & Children: Insights from a Farm Sanctuary" and a special issue of Time magazine called "The Animal Mind: What they're thinking and feeling, and how to understand them" by Jeffrey Kluger are must-reads. They're easy ways to catch up on the fascinating lives of other animals.

Chimpanzees: Former Pets or Performers Suffer For Years

A recent study shows that chimpanzees who are reared in captivity and who lacked contact with other chimpanzees behave abnormally for years after being pets or performers. I hope this study receives a lot of attention from people working on a wide range of animals. We owe it to the animals to do the best we can so that they can live the best lives possible in our care.

"I Need my Mama" Distress Calls are Similar Across Mammals

Distress calls emitted by young of different mammalian species share basic elements. They are simple sounds with few pitch changes. A recent study has shown that wild mule deer mothers respond to the distress calls of infant deer, seals, marmots, dogs, cats, bats, humans, and other mammals. When a youngster needs help, he or she needs it then, not later. Moms know best.

What Do We Really Know About Lethal Violence in Chimps?

Lethal violence in other animals is extremely rare and it's not clear what it says about us. An essay in today's New York Times by James Gorman called "Lethal Violence in Chimps Occurs Naturally, Study Suggests" summarizes a recent study published in the journal Nature, concerned with 152 killings of which 58 (38%) were observed, 41 inferred (27%), and 53 (35%) suspected.

Beaglemania: Watching this Video May Change Your Life

In May 2014, The Beagle Freedom Project released nine beagles who had never known sunlight, kindness, touch, safety, or love. The depth of their unbounded joy on their first foray onto grass and meeting other beagles cannot be captured in words. Please watch this video and share it with everyone you know. Their forgiveness and resilience should be a model for all of us.

Getting Research Chimpanzees into Sanctuary is Easy

Alison Eastwood's campaign through to help get laboratory chimpanzees who were used in various types of biomedical research into a sanctuary called Chimp Haven sets an example of just what needs to be done to ensure that these individuals get to live out their lives in peace and safety as soon as possible.

Fish Rival Chimpanzees in Forming Cooperative Relationships

Trout seek out moray eels with whom to cooperate to get a meal. The trout use head shakes and headstands to tell the eel where the prey is hiding. In addition, the trout know when they need a collaborator and pick the best eel with whom to work. The fish perform as well, if not better, than chimpanzees in similar collaborative tasks. Brain size doesn't matter.

Dogs: Do They Really "Play Dumb" For Us?

Do dogs really dumb down to please us? Despite claims that they do, this sweeping conclusion is premature given existing data. Furthermore, given that there is incredible variability among different breeds and among individuals of the same breed, talking about "the dog" (or "the wolf") could surely be terribly misleading. Maybe individual dogs do, but we really don't know.

Birds and Us: Should Cormorants Be Killed to Save Salmon?

Two recent essays and an excellent book highlight how we view these magnificent animals and why birds and other animals are so important to us and to Earth's magnificent diverse ecosystems. We can and must do better in our interactions with other animals. We owe it to them and of course we owe it to ourselves and to future generations.

Sperm: Group Living Swimmers Come Together and Arrive Early

Group living sperm, when compared to single sperm, swim in a straighter line in a promiscuous species of mice to reduce competition. Thus, group living sperm arrive at their destination sooner than solo sperm, not because they swim faster, but because they travel a shorter distance.

Animal Suffering Isn't An Enigma So Let's Get Over It

An essay in the New York Times called "The Enigma of Animal Suffering" raises many important issues and needs to be countered given what we know about the emotional lives of sentient beings using solid evolutionary theory and empirical facts. Animal suffering isn't any more enigmatic than human suffering so we should stop pretending we don't know what animals want or need.

Last Chain On Billie: A Must Read Elephant's Biography

If you read only one book on the brutal abuse and remarkable recovery of animals in entertainment, this is it. Carol Bradley's "Last Chain on Billie" is a fact-filled page-turning biography of a magnificent circus elephant's long, painful, and unpredictable journey from reprehensible confinement and egregious abuse to freedom, and much more.

Is This Dog Really Trying to Save the Fish Out of Water?

A video of a dog trying to place water on grounded fish raises many interesting questions. Just what is going on in the dog's head and heart? Is the dog trying to save the fish, trying to bury them, or? This video is a great catalyst for getting readers involved in the discussion. Cross-species friendships, called odd couples, and empathy, are not all that uncommon.
