DEAR READERS: Coyotes are essentially monogamous, and they form strong pair bonds. Scientists have now documented changes in the brains of coyotes who lose a mate, shedding light on grief experienced by people who lose a loved one.
See the study "Evaluating the stress system of the grieving brain: Corticotropin-releasing factor receptors and partner loss in coyotes" by Rachel Tong and Sara Freeman, published in Neuroscience in 2025.
On a closely linked issue, coyote-killing contests, along with the routine trapping, poisoning and shooting of these animals, should be prohibited -- both for reasons of compassion and because their extermination does not protect livestock, according to one detailed analysis. See the 2017 article by conservation biologist Megan Draheim, "Why Killing Coyotes Doesn’t Make Livestock Safer," posted on TheConversation.com.
Draheim writes, “To keep coyotes in check, (USDA) employees set neck snares and other traps, shoot coyotes on the ground and from planes and helicopters, arm sheep with collars containing liquid poison and distribute M-44 'bombs' that inject sodium cyanide into the mouths of animals that chew on them.
"As in warfare, there is collateral damage," she continues. "M-44s killed more than 1,100 domestic dogs between 2000 and 2012. Scientists have also criticized (the USDA) for unintentionally killing numerous animals and birds, including federally protected golden and bald eagles, while failing to do any studies of how its actions affected nontarget species.”
She also underscores the superiority of nonlethal methods of predator control, stating, “One 2016 analysis reviewed studies that compared lethal and nonlethal strategies for controlling livestock predation. ... The review found that nonlethal methods generally reduced livestock predation more effectively, and that predation actually temporarily increased after use of some lethal methods.”

PROHIBIT WILDLIFE TRAFFICKING FOR FOLK MEDICINE
The amazing pangolins of Africa and India are being poached and killed for their scales, which are used in folk medicine remedies by several cultures. Also sought are bones from tigers and bile from bears. For details, go to: fourpawsusa.org/campaigns-topics/topics/help-for-bears/protecting-u-s-bears-from-the-bile-trade.
In some parts of China, bears are still kept in narrow cages for years so that people can extract bile from their abdomens, in flagrant disregard of international appeals to stop the practice. The bear bile extraction industry in China has experienced a recent surge in demand, driven primarily by a 2022 research paper suggesting that a compound in bear bile might help treat COVID-19 symptoms and the government’s official endorsement of a bile injection for this purpose.
South Korea, at least, just banned bear bile farming in December because of massive public pressure. Meanwhile, elephant ivory is still being smuggled for various arts and crafts, along with the furs, feathers, skins and fins of increasingly endangered species in many countries. The legal and illegal international trade in wildlife -- tropical fish, birds, reptiles, amphibians and even monkeys -- should be prohibited. Doing so would not only aid conservation but also reduce the risk of pandemic diseases, especially from monkeys and other mammals, and cut down on the introduction of new diseases to indigenous wildlife and farmed animals. I document the urgency of this issue in my 2025 book, “One Health: Veterinary, Ethical and Environmental Perspectives.”
Most concerning are the so-called “wet markets” across Asia, where various species -- some domesticated, others wild-caught or bred in captivity, like racoon dogs -- are sold and slaughtered. Perhaps this is where President Trump might apply some economic leverage on China, combined with ethical appeals to save the bears, for a start. After that, we must get all nations to address wildlife trafficking, which is closely aligned with sex and drug trafficking.
