Eastern Gray Squirrel
The eastern gray squirrel (''Sciurus carolinensis''), also known, particularly outside of North America, as simply the grey squirrel, is a tree squirrel in the genus ''Sciurus''. It is native to eastern North America, where it is the most prodigious and ecologically essential natural forest regenerator. Widely introduced to certain places around the world, the eastern gray squirrel in Europe, in particular, is regarded as an invasive species. In Europe, ''Sciurus carolinensis'' is included since 2016 in the list of Invasive Alien Species of Union concern (the Union list). This implies that this species cannot be imported, bred, transported, commercialized, or intentionally released into the environment in the whole of the European Union. Distribution ''Sciurus carolinensis'' is native to the eastern and midwestern United States, and to the southerly portions of the central provinces of Canada. The native range of the eastern gray squirrel overlaps with that of the fox squirre ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Western Gray Squirrel
The western gray squirrel (''Sciurus griseus'') is a tree squirrel found along the western coast of the United States and Mexico. In some places, this species has also been known as the silver-gray squirrel, the California gray squirrel, the Oregon gray squirrel, the Columbian gray squirrel and the banner-tail. There are three geographical subspecies: ''Sciurus griseus griseus'' (central Washington to the western Sierra Nevada in central California); ''S. g. nigripes'' (from south of San Francisco Bay to San Luis Obispo County, California); and ''S. g. anthonyi'' (which ranges from San Luis Obispo to northern Baja California). In some landscapes, the Western grey squirrel has lost habitat or experienced local extinction due to competition with other squirrel species and other pressures on their population. Description The western gray squirrel was first described by George Ord in 1818 based on notes taken by Lewis and Clark at The Dalles in Wasco County, Oregon. ''Sciurus gr ...

Arizona Gray Squirrel
The Arizona gray squirrel (''Sciurus arizonensis'') is a tree squirrel, in the genus ''Sciurus'', endemic to the canyons and valleys surrounded by deciduous and mixed forests in eastern Arizona and northern Mexico. It is threatened by habitat loss. The only other large squirrel that is within its range is Abert's squirrel, which has ear tufts and lives in pine forests. Although they act and look like other gray squirrels, the Arizona gray squirrel is actually more closely related to the fox squirrel. Phylogeny and description ''Sciurus arizonensis'' is a member of the order Rodentia and the family Sciuridae. It is distinguishable from ''Sciurus aberti'' by its longer flatter skull, broader rostrum, and having only one molar instead of two. ''S. arizonensis'' also has smaller ears with no tufts and a red/black stripe on the underside of their tail. Some sexual dimorphism can be seen in these squirrels, but it varies with some populations having larger males, and other populations ...

Mexican Gray Squirrel
The Mexican gray squirrel (or red-bellied squirrel) (''Sciurus aureogaster'') is a tree squirrel in the genus ''Sciurus'' native to Guatemala and eastern and southern Mexico. It has been introduced to the Florida Keys. The alternate name should not be confused with the Indonesian red-bellied squirrel (''Rubrisciurus rubriventer'') or the Asian red-bellied tree squirrel (''Callosciurus erythraeus''). Behaviour Since the introduction of the species to Florida in the late 1930s, its nesting locations have become more irregular, nesting in varying species of trees and even choosing to nest in hurricane debris. Ecology ''Sciurus aureogaster'' has had an extremely negative impact on ''Thrinax radiata'' populations on Elliot Key. It uses palm fibers as nesting materials and consumes the palm itself, often killing the plant. Subspecies The two subspecies each have many synonyms associated with them: * The subspecies ''S. a. aureogaster'' was also known as ''S. a. chrysogaster'', ''S ...
