  "account": "Cougars, also known as pumas or mountain lions, have been found to reduce deadly vehicle-deer collisions in the U.S. by up to 76%, according to a recent study published in the journal Current Biology. The research highlights how the presence of these big cats influences the behavior of their prey, black-tailed deer, in the Olympic Peninsula region of Washington state.\n\nBlack-tailed deer thrive in their natural habitat, with an abundance of food in familiar forests and meadows. However, they remain cautious as they are prey species and share their habitat with predators such as Cascade mountain wolves, cougars, and black bears. Cougars, with their stealthy movements, pose the greatest threat to the deer. As their favorite meal, cougars significantly impact the deer's movement patterns, influencing where, when, and how they forage for food, water, and rest.\n\nThe study emphasizes that the presence of cougars changes the landscape usage of their prey, keeping humans safer by encouraging deer to stay away from roads and potential collision zones. Nationwide, there are 1.6-2.1 million accidents involving deer in the U.S. every year, resulting in 200-440 fatalities and causing an estimated $10 billion in damages annually. Cougars, while not actively patrolling highways, indirectly protect humans by pushing black-tailed deer away from high-traffic areas.",
  "summary": "If you’re a black-tailed deer on the Olympic Peninsula in the U.S. state of Washington, you’re always surrounded by friends and family. You are free-range, with abundant food to forage in familiar woods and meadows. But you’re also vigilant because you’re a prey species and your ideal habitat is also home to your top predators: […]",
