Richardson's ground squirrel (Urocitellus richardsonii), also known as the dakrat or flickertail, is a North American ground squirrel in the genus Urocitellus.Like a number of other ground squirrels, they are sometimes called prairie dogs or gophers, though the latter name belongs more strictly to the pocket gophers of family Geomyidae, and the former to members of the genus Cynomys.
The vocalization is sometimes confused with that of the horned lark, and, in areas where the two species are sympatric, with round-tailed ground squirrels. Mohave ground squirrels can occasionally be sighted perched in Lycium cooperii or in Creosote bush (Larrea tridentata) during mid-morning (9-11 a.m.) hours (April–June) basking in the sun.
The fox squirrel (Sciurus niger), also known as the eastern fox squirrel or Bryant's fox squirrel, [3] is the largest species of tree squirrel native to North America.It is sometimes mistaken for the American red squirrel or eastern gray squirrel in areas where the species co-exist, though they differ in size and coloration.
The currently accepted scientific name for Abert's squirrel is Sciurus aberti Woodhouse, 1853. [4] Woodhouse had initially described the species as Sciurus dorsalis in 1852, but this name turned out to be preoccupied by Sciurus dorsalis Gray, 1849 (now a subspecies of variegated squirrel S. variegatoides), and thus the present species was renamed.
It is also said to kill domestic chickens and eat their hearts and livers. Although this may seem far-fetched, the naturalist Edward Banks recorded in 1949 that the squirrel was "wary, difficult to observe and biting fiercely", and other species of squirrel are known to be active hunters of small vertebrates.
Eastern gray squirrels are crepuscular, [24] or more active during the early and late hours of the day, and tend to avoid the heat in the middle of a summer day. [40] They do not hibernate. [41] Eastern gray squirrels can breed twice a year, but younger and less experienced mothers normally have a single litter per year in the spring.
Environmental officials killed moose in Connecticut after it wandered onto the grounds of a major airport. The moose was spotted Friday morning wandering along a road at Bradley International Airport.
The wolf must give chase and gain on its fleeing prey, slow it down by biting through thick hair and hide, and then disable it enough to begin feeding. [4] After chasing and then confronting a large prey animal, the wolf makes use of its 6 cm (2 + 1 ⁄ 2 in) fangs and its powerful masseter muscles to deliver a bite force of 28 kg/cm 2 (400 lbf/in 2), which is capable of breaking open the ...
