American Black Bear

The American Black Bear.

Information
Write the first  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. It is listed by the  IUCN  as  Least Concern, due to the species' widespread distribution and a large global population estimated to be twice that of all other bear species combined. Along with the  brown bear, it is one of only two of the eight modern bear species not considered globally threatened with extinction by the IUCN. American black bears often mark trees using their teeth and claws as a form of communication with other bears, a behavior common to many species of bears. [1] section of your page here.

Height and Weight
Write the second sec 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). [5] [37]  In the state of  California, studies have indicated that the average mass is 86 kg (190 lb) in adult males and 58 kg (128 lb) in adult females. [32]  Adult black bears in Yukon Flats National Wildlife Refuge  in east-central  Alaska  were found to average 87.3 kg (192 lb) in males and 63.4 kg (140 lb) in females, whereas on Kuiu Island  in southeast Alaska (where nutritious salmon are readily available) adult bears averaged an estimated 115 kg (254 lb). [38] [39]  In  Great Smoky Mountains National Park, adult males averaged 112 kg (247 lb) and adult females averaged 47 kg (104 lb) per one study. [40]  In  Yellowstone National Park, a population study found that adult males averaged 119 kg (262 lb) and adult females averaged 67 kg (148 lb). [41]  In  New York state, the two sexes reportedly average 135 kg (298 lb) and 74 kg (163 lb), respectively. [42]  Adults typically range from 120 to 200 cm (47 to 79 in) in head-and-body length, and 70 to 105 cm (28 to 41 in) in shoulder height. The typically small tail is 7.7–17.7 cm (3.0–7.0 in) long. [34] [43] [44] [45]  Although they are the smallest species in  North America, large males exceed the size of other bear species except the  brown  and  polar bears. [34]  The biggest wild American black bear ever recorded was a male from  New Brunswick, shot in November 1972, that weighed 409 kg (902 lb) after it had been dressed, meaning it weighed an estimated 500 kg (1,100 lb) in life, and measured 2.41 m (7.9 ft) long. [46]  Another notably outsized wild black bear, weighing in at 408 kg (899 lb) in total, was the cattle-killer shot in December 1921 on the Moqui Reservation in  Arizona. [46]  The record-sized bear from  New Jersey  was shot in  Morris County  December 2011 and scaled 376.5 kg (830 lb). <sup class="reference" id="cite_ref-47" style="line-height:1em;unicode-bidi:-webkit-isolate;font-family:sans-serif;">[47]  Even larger, the most massive black bear recorded in  Pennsylvania  (one of six weighing over 363 kg (800 lb) shot in the in the last 15 years in the state) weighed in at 399 kg (880 lb) and was shot in November 2010 in  Pike County. <sup class="reference" id="cite_ref-48" style="line-height:1em;unicode-bidi:-webkit-isolate;font-family:sans-serif;">[48]  The North American Bear Center, located in  Ely, Minnesota, is home to the world's largest captive male and female black bears. Ted, the male, weighed 431–453.5 kg (950–999.8 lb) in the fall of 2006. <sup class="reference" id="cite_ref-49" style="line-height:1em;unicode-bidi:-webkit-isolate;font-family:sans-serif;">[49]  Honey, the female, weighed 219.6 kg (484 lb) in the fall of 2007. <sup class="reference" id="cite_ref-50" style="line-height:1em;unicode-bidi:-webkit-isolate;font-family:sans-serif;">[ tion of your page here.
