It's no secret that a bear's appetite sees a serious uptick during their hyperphagia phase -- basically when they're packing on the pounds for winter hibernation.

During this time, Colorado's black bears can eat up to 20,000 calories of food per day. An image recently published by Colorado Parks and Wildlife shows just how much food that is.

While exact details of the food weren't revealed, here's a breakdown of what the photo appears to capture:

  • A dozen doughnuts from Dunkin' (roughly 270 calories each for 3,240)
  • An order of Pizza Hut cinnamon sticks (800 calories)
  • A medium Pizza Hut pepperoni pizza (1,760 calories)
  • Two McDonald's double cheeseburgers (437 each for 874 total calories)
  • One Sonic sandwich (perhaps the 600-calorie Sonic cheeseburger)
  • A Starbucks coffee (perhaps the Pumpkin Spice Latte for 380 calories)
  • A Jimmy John's sandwich (perhaps the Turkey Tom for 480 calories)
  • A Chipotle burrito (chicken burrito is roughly 1,000 calories)
  • A chili-cheese hot dog from Sonic (470 calories)
  • A chili-cheese tater tots from Sonic (530 calories)
  • McDonald's smoothie (240 calories)
  • Chicken bucket from KFC (10-piece for 850 calories)
  • McDonald's fries (320 calories)
  • Five Hershey's with almonds chocolate bars (210 calories each for 1,050 total)

* All calorie estimates are a best guess based on the image and details provided on company websites. Actual calories may vary.

In a very unofficial calorie estimation, the food in the photo equates to about 12,500 calories, which means a bear might be eating even more than what is seen on a daily basis.

This shows how wild a bear's appetite is during hyperphagia, making it crucial to keep non-natural food sources secure. If living in bear country, make sure all trash sources can't be accessed and do your part to keep Colorado's wildlife wild.
