The concept of a home range was introduced by W. H. Burt in 1943. He drew maps showing where the animal had been observed at different times.
An animal chooses its territory by deciding what part of its home range it will defend. In selecting a territory, the size and quality play crucial roles in determining an animal's habitat. Territory size generally tends to be no larger than the organism requires to survive, because defending a larger territory incurs greater energy, time and ...
Home range sizes and overall cougar abundance depend on terrain, vegetation, and prey abundance. [87] Research suggests a lower limit of 25 km 2 (9.7 sq mi) and upper limit of 1,300 km 2 (500 sq mi) of home range for males. [88] Large male home ranges of 150 to 1,000 km 2 (58 to 386 sq mi) with female ranges half that size. [89]

The range of a male wolverine can be more than 620 km 2 (240 sq mi), encompassing the ranges of several females which have smaller home ranges of roughly 130–260 km 2 (50–100 mi 2). Adult wolverines try for the most part to keep nonoverlapping ranges with adults of the same sex. [24]
Overall, the annual mean home range for males was 782 ha (1,930 acres) and for females was 538.7 ha (1,331 acres). [116] The breeding range's mean home size in Washington was 321 ha (790 acres), while it was 971 ha (2,400 acres) in the non-breeding season. Barred owl bathing in Brett Woods, Fairfield CT US
