American Black Bear
The American black bear (Ursus americanus) is a medium-sized bear native to North America. It is the continent's smallest and most widely distributed bear species. Black bears are omnivores with their diets varying greatly depending on season and location. They typically live in largely forested areas, but do leave forests in search of food. Sometimes they become attracted to human communities because of the immediate availability of food. The American black bear is the world's most common bear species.
Black bear weight tends to vary according to age, sex, health, and season. Seasonal variation in weight is very pronounced: in autumn, their pre-den weight tends to be 30% higher than in spring, when black bears emerge from their dens. Black bears on the East Coast tend to be heavier on average than those on the West Coast, although black bears follow Bergmann's rule and bears from the northwest are often slightly heavier than the bears from the southeast. Adult males typically weigh between 57–250 kg (126–550 lb), while females weigh 33% less at 41–170 kg (90–370 lb).
Cougar
The cougar (Puma concolor), also known as the mountain lion, puma, panther, mountain cat,[3] or catamount, is a large cat of the family Felidae native to the Americas. Its range, from the Canadian Yukon to the southern Andes of South America, is the greatest of any large wild terrestrial mammal in the Western Hemisphere.[4] An adaptable, generalist species, the cougar is found in most American habitat types. It is the second heaviest cat in the Western Hemisphere, after the jaguar. Solitary by nature and nocturnal,[5] the cougar is most closely related to smaller felines and is nearer genetically to the domestic cat than true lions.
Cougars are slender and agile members of the cat family. They are the fourth-largest cat;[30] adults stand about 60 to 90 cm (24 to 35 in) tall at the shoulders.[31] Adult males are around 2.4 m (7.9 ft) long nose-to-tail and females average 2.05 m (6.7 ft), with overall ranges between 1.5 to 2.75 m (4.9 to 9.0 ft) nose to tail suggested for the species in general.[32][33] Of this length, 63 to 95 cm (25 to 37 in) is comprised by the tail.[34] Males typically weigh 53 to 100 kg (115 to 220 lb), averaging 62 kg (137 lb). Females typically weigh between 29 and 64 kg (64 and 141 lb), averaging 42 kg (93 lb).[35][34][36] Cougar size is smallest close to the equator, and larger towards the poles.[4] The largest recorded cougar, shot in Arizona, weighed 125.5 kg (276 lb) after its intestines were removed, indicating in life it could have weighed nearly 136.2 kg (300 lb).[37] Several male cougars in British Columbia weighed between 86.4 and 95.5 kg (190 to 210 lb).[38]
