Most wild animals will retreat when faced with a larger and stronger opponent.

Camera trap compilation of Los Angeles National Park, showing a very interesting overlap in territory between American Black bears and the local Mountain lion population.

/\ I am also surprise there are no bobcats killed either. Bobcats and smaller and weaker than cougars.

So a cougar cant even kill a god damn black bear but 150 years ago it used to kill grizzly bears that were even larger than modern grizzly bears? Doesn't smell so good.

"Conversely, adult black bears are larger than cougars (weights of female bears in New Mexico range from 55 to 70 kg [120 to 155 lbs]; males are larger, with a minimum reported weight of 90 kg [200 lbs]; Chapter 16), and they may dominate cougars at cache sites. Some bears may rely on cougar-killed prey during the lean times in early spring and prior to denning in the fall. In California, black bears usurping ungulate carcasses from cougars caused the cougars to compensate for the loss of food by increasing their kill rates of ungulates (Elbroch et al. 2015d). In Yellowstone and Glacier national parks, black and grizzly (Ursus arctos horribilis) bears visited cougar kills and often displaced the cougars (Murphy et al. 1998)."
Page 512 - 513:
With the absence of grizzlies from New Mexico, black bears overall likely exhibit low levels of competition with the state’s other larger carnivores, such as cougars, coyotes, bobcats, and wolves, due to differences in their diets, diel activity patterns, and reproductive cycles (Maehr 1997). Nonetheless, one likely form of interference competition is kleptoparasitism (i.e., food stealing). Kleptoparasitism can represent a nutritional windfall for the usurper and a significant nutritional loss to the victim. For example, black bears have been observed to usurp kills from cougars. In Glacier and Yellowstone national parks, Murphy et al. (1998) estimated that the biomass of cougar prey stolen by grizzly and black bears represented a gain of 71–113% of the daily energy needs of the bears, but a loss of 17–26% of the daily energy requirements of the cougars. Due to their large size, black bears are likely the winner in most contests with cougars, coyotes, and bobcats.
