When I was working up in Northern Ontario, I came across a sign for bear trails and spoor to watch out for as the camp has a serious bear problem with them being attracted by the garbage dump. It started with the warnings that all bears are dangerous, and that the area I was working in was indigenous to several types of bear. The warning continued with the suggestion to wear noisemaker bells, carry bear repellent (like pepper spray) and to make yourself as large and intimidating as possible, not to run away or flee from the animal, but to scare it away with loud noises and shouting while backing away slowly. It continued with the Black bear, describing its tendency to have a fairly small pawprint, about the size of your hand, and its spoor tends to be fairly small with berries and some twigs mixed within it, and usually found at the mine dump picking through garbage. The Brown bear is larger, and more aggressive, tending to fish and hunt near streams for fish and other food, but is not adverse to picking the garbage either. Its spoor is larger than the Black bear, and its pawprint is larger and tends to be deeper due to the heavier weights involved. The Grizzly Bear is another type of bear and it tends to follow the profile for the other bears, just larger and can be very aggressive. The final bear is the Polar Bear, occupying the shorelines along Hudson's Bay and is the largest bear on the planet. You can tell its pawprint is exceptionally large, and its spoor has little bells in it and smells like pepper.

have a great day!
