  Sciurus Carolinensis

(Above: Grey Squirrel by Me)

 A tree squirrel native to the Eastern to the Midwestern United States and the Eastern provinces of Canada. It was Introduced to the western United States and it thrives there as well. The Eastern Gray Squirrel was also introduce to the UK and has displaced the Red Squirrel, which has aroused some concerns.  The fur is mostly gray and can sometimes have a red tinge. The underbelly is all white.  Eastern Gray Squirrels have large bushy tail. In urban areas, both the Albino and the melanistic version of the Gray Squirrel can be found. Squirrels are hoarders, burying small caches of food for later.  Contrary to belief; squirrels have a very god memory for finding their caches. Gray Squirrels can make a variety of sounds, a "buck, buck, buck" which is usually followed by a "kyukyukyuuuuuuuu." These squirrels nest in "dreys," which are a type of nest. Squirrels will invade bird feeders for millet and sun flower seeds, now safflower is used as squirrels do not seem to like it. Some seed is covered in pepper coating because only mammals can taste the capsaicin.  They have also been known to dig up flower bulbs. (Above: An Eastern Gray surveys the land below.

Javelina (or Peccary)

 (Pecari Tajacu) (Tayassu Pecari) (Catagonus Wagneri)

(Above: 'Boaring' Javelinas by Ange)  

Peccaries are medium sized mammals and are of the family Tayassuiade. They are members of the Artiodactyls or even-toed ungulates like pigs and hippos. They are found in Southwestern US and throughout Central and South America. Peccaries measure between 3-4 feet in length and weigh in at 44-88 pounds full grown. Peccaries are often confused with razorback hogs. The difference is all in the tusk! A peccary's tusk is short and straight while an Old World pig's tusk is long and curves around on its self. Peccaries use the tusk for self defense, their diet is mostly roots and grasses but they will also feed on invertebrates and small vertebrates. A peccary's temperament is aggressive enough where they cannot be domesticated as they will injure humans. They first appeared 32 million years ago in America. Extinct species have been found in Oregon. Javelinas did not reach South American until about 3 million years ago, when they migrated south with the llamas and tapirs.

Bighorn Sheep

  (Ovis Canadensis) 

(Above: Bighorn Sheep by Ange)

Wild sheep crossed the Bering Land Bridge from Siberia and have spread as far south as Baja California and the northern Mexican border. Around 1900 hunting, domestic sheep competition, and disease had dwindled the population from an estimated 2 million to just several thousand. They are hunted for their meat and their horns. They are also a source of eco-tourism, tourists come to see the famed bighorn sheep in their habitat. They are named for the large horns on the rams, the females, or ewes, have horns but they are not as large or striking as the rams. They range from grey to chocolate brown withe a white rump. They graze on grasses and shrubs, and seek minerals and natural salt-licks. They are adapted to covering steep terrain to avoid predators such as, coyotes, eagles, and cougars. Before the rutting season the males develop a hierarchy by head butting each other.

(Above: Opossum by Hard-Rain

Possums are opportunistic omnivores. The expression "Playing Possum" comes from the behavior that they exhibit while threatened, mimicking the sight and smell of a sick or dead animal. They draw the lips back, teeth are bared, and they smell foul due to a secretion from the anal glands. This is involuntary. The best thing to due when seeing a seemingly dead or sick possum is to leave it be, in a clear area.
