| Urban Coyotes... Click on link below to see photo slide (WARNING, pic #6 might be hard to see for some people) & video. Remember, coyotes can jump high walls & fences! ALWAYS supervise your pet(s) when outdoors. How do coyotes thrive in Southern California? Scientists dissect 200-plus carcasses to find clues – Press Enterprise By Lauren Williams | lawilliams@scng.com | Orange County Register PUBLISHED: June 8, 2017 at 10:57 am | UPDATED: June 13, 2017 at 1:47 pm How do coyotes thrive in Southern California? Scientists dissect 200-plus carcasses to find clues The coyote known as CY120 thawed in a cooler, awaiting his rendezvous with eternity. Death? No, CY120 already was long gone. But CY120’s carcass — specifically, the contents of his stomach — was about to become a data point in a growing body of knowledge, part of a research project underway at several Southern California universities to learn more about the mysterious lives and sometimes sudden deaths of urban coyotes. Big data, coyote style Coyotes are common throughout the Inland region. This month, Fontana police warned residents to be vigilant after several coyote sightings. And in late May, a Riverside County animal services officer found an abandoned coyote pup under a bush in Jurupa Valley. What researchers learn from the dissections of 200-plus coyotes could upend our understanding of the clever, adaptable predators and, perhaps, lead coyotes and humans and our pets to some form of peaceful coexistence. Or, short of that, lessen the coyote killing and pet eating. What researchers learn from the dissections of 200-plus coyotes could upend our understanding of the clever, adaptable predators and, perhaps, lead coyotes and humans and our pets to some form of peaceful coexistence. Or, short of that, lessen the coyote killing and pet eating. Big data, coyote-style Learning from CY120, and the collection of big coyote data in general, is not pleasant. On a recent Friday, CY120’s stomach was part of three coyote carcasses sliced into, emptied and cataloged by Danielle Martinez, a graduate biology student at Cal State Fullerton. After using a scalpel to open the underbelly and slice into the stomach itself, Martinez – 26, from Glendora and not easily grossed out – picked visibly identifiable matter away from the remains of CY120’s last few meals. She noted some twigs and a broken leaf that remained intact, puzzled over small bone fragments and set aside chunks of flesh for later analysis. The process unleashed a pungent yet sweet odor, a mix of rotten fruit, compost and bleach. Once emptied, CY120’s stomach resembled a deflated balloon. Stomachs are just a small part of the broader coyote project. Coyote heads and brains are being studied at Cal State Long Beach. Coyote mange, when applicable, is being examined by researchers at the state Department of Fish and Wildlife in Sacramento. Ticks, fleas and mites plucked from coyote hides are being studied by Orange County Vector Control; livers and other organ samples are going to UCLA, Texas and elsewhere for genetic analysis. Whiskers, fur, ears — all are being used to analyze coyote dietary habits and to create each coyote’s individual DNA profile. “I kind of jokingly say we’re kind of a coyote rendering plant,” said Niamh Quinn, a coyote researcher and the human-wildlife interactions adviser for the University of California Cooperative Extension. “Because we have the whole carcass, we can look at the relationship between diet, health, disease and the relationships among coyotes in different areas. “You really get this big picture from a carcass that you don’t get from the scat,” she added. The coyotes come from throughout the state. Caltrans, animal control departments and private trappers regularly donate carcasses to Quinn’s project, which, in turn, distributes the bodies to the applicable scientists. Quinn stressed that no one is being paid to kill coyotes and that the animals are dying of natural causes or normal human-coyote interactions. It’s all being done in the name of human-coyote conflict avoidance, if not resolution. “Obviously coyotes are here to stay in urban areas,” Quinn said. “But we want to know more about them to know how to interact with them.” Heads in the freezer Some researchers hope to learn about the specific diseases that coyotes carry and can spread to people and their pets. Others, like Martinez, want to sort out what plants and animals coyotes rely on so that people will plant less enticing fare. Ted Stankowich, a biology professor at Cal State Long Beach, has 100 coyote heads stuffed into a freezer at work. He’s an expert on mammals, and his freezer has other bodies and body parts, including a cheetah, giraffe legs and a kangaroo donated from the San Diego Zoo. The coyote heads, he hopes, will provide answers to questions he has about the differences between rural and urban coyotes. The brains could tell part of that story. Is the musculature different in urban and rural coyotes? Do urban coyotes have weaker jaws because they’ve learned to survive off pet food? Are they more or less social than rural coyotes? How does diet shape and change the coyote body? “The thing that allows a coyote to thrive in a rural area may be different than coyotes in an urban area,” Stankowich said. “Anything we can extract from these animals, we’re going to get it because it’s a great resource to have.” Stankowich plans to start his dissections in the fall with one of his biology students. The practice of working with actual animal carcasses proves to be invaluable preparation for students planning to go on to study human or animal health. “As an educational tool it’s fantastic,” he said. “For students interested in going on to veterinary or medical school, the practice of working on actual animal tissue, and familiarity with the muscles of the head, is great experience.” Cat lovers? Martinez is one such student. This summer, between her first and second years of grad school, she plans to dissect and sort more than 200 coyote stomachs. Her research specifically examines how often coyotes prey on domestic cats. The process is part veterinary science, part detective work. “I actually do have a lot of fun doing this,” she said, “once you get used to the smell.” So far, some of what Martinez has found sounds like standard fare for toothy omnivores that live near population centers. Urban coyotes enjoy dining on many members of the rodent family, including black “roof rats” that live on suburban houses, Norway rats and pocket gophers. She’s also seen stomachs filled with seeds and, in one case, Jerusalem crickets. But she’s also been surprised. She’s seen bits of raccoon and Styrofoam. And, in one stomach, she found pieces of a fairly large dog paw — claws and all — along with black flies, indicating the large dog had been road kill. So far, however, she hasn’t identified any cats. How CY120 came to Martinez isn’t clear. He was found in Newport Beach in August, but how he died — from a car encounter or starvation or some other fate — wasn’t information made available to Martinez. In addition to the leaf and twigs and bones, Martinez noted that CY120 had eaten cartilage. She passed the contents of CY120’s stomach eventually to another student for DNA analysis. Quinn, who quarterbacks the project from her Irvine office, believes the end result will help the animals and help people learn to live near them. “Knowing what coyotes eat is a huge help in their management,” Quinn said. “We can make a lot of management recommendations, we can make disease intervention decisions. All of this is really, really important.”

| Sad story, 9 yr old Yorkie attacked & killed by coyote right in his own backyard... https://patch.com/california/redondo...tbreaking-tale I can't STRESS enough, PLEASE supervise your pets when they're outside, don't leave them alone for even a second. Especially if hawks & other predatory birds & coyotes have been spotted in your area. We have coyotes here & I've encountered one just down the street from us. I never let them go out to the backyard alone.

| We live in the Country.....Katy can not go out alone! A really good friend of mine lived on a Mountain in TN. TWO of her JRT were not only killed, mangled and eaten. Take. This. Threat. Serious! Wildlife is NOT kind. |

| They are actually been seen more and more in neighborhoods where we would be least likely to expect to see them. |

| The video wasn't gory, you can watch it. Hawks are a protected by law bird. If it is found that you killed one, even if it had your wee little baby in it's claws and killing the hawk was the only way to save your precious baby you would be served with a hefty fine. One of our members faced this very thing, her little yorkie actually killed the hawk that was attracting him, she was going to be fined as the one that killed the bird.
