Tamiops. In addition to having denser fur, which may help insulate it at higher elevations, dorsal stripes appear to be less brilliant than those seen in closely related species and stop at the shoulders rather than connecting with the cheek stripes. Females have longer tails than males by about 1.8%, which is typical of arboreal species. (Hayssen, 2008a; Hayssen, 2008b; Li, et al., 2006; Ren, et al., 2004)is small bodied, with characteristic light yellow stripes extending from nose to neck on both sides of the body. It also has characterisic white tufts of hair at the posterior tips of the ears. Cinnamon and yellow stripes run the length of the dorsum, extending from the caudal portion of the torso to the base of the tail. No data exists on the average size and weight of this species, though it appears to be larger than other members of

sciurids: chase, avoid, ignore, and follow. Chasing occurs primarily between adult males, whereas avoid and ignore are common between both genders and all age classes. Follow most often occurs between females and young or between males and females. (Hayssen, 2008a; Hayssen, 2008b; Tamura, 1993; Van der Meer, et al., 2008)is diurnal and arboreal. It nests, forages and mates in the canopy and possesses strong adaptations for arboreal locomotion. It is typically social, but there is no evidence of organized social hierarchies. It primarily forages during the day, and like many seed eating mammal and bird species, creates food caches. Although little is know of the general behavior of specifically, four primary behaviors have been observed during conspecific encounters of
The average home range size for (Hayssen, 2008b)is unknown.

Economic Importance for Humans: Positive
There are no known positive effects of Tamiops swinhoei> on humans. However, hunting of small mammals is common in Southeast Asia, and this species may function as a food source for humans throughout their geographic range. (Wells, et al., 2007)

Economic Importance for Humans: Negative

uses sound to communicate
Referring to an animal that lives in trees; tree-climbing.
- bilateral symmetry
having body symmetry such that the animal can be divided in one plane into two mirror-image halves. Animals with bilateral symmetry have dorsal and ventral sides, as well as anterior and posterior ends. Synapomorphy of the Bilateria.
uses smells or other chemicals to communicate
- active during the day, 2. lasting for one day.
animals that use metabolically generated heat to regulate body temperature independently of ambient temperature. Endothermy is a synapomorphy of the Mammalia, although it may have arisen in a (now extinct) synapsid ancestor; the fossil record does not distinguish these possibilities. Convergent in birds.
A substance that provides both nutrients and energy to a living thing.
an animal that mainly eats seeds
An animal that eats mainly plants or parts of plants.
offspring are produced in more than one group (litters, clutches, etc.) and across multiple seasons (or other periods hospitable to reproduction). Iteroparous animals must, by definition, survive over multiple seasons (or periodic condition changes).
having the capacity to move from one place to another.
- native range
the area in which the animal is naturally found, the region in which it is endemic.
found in the oriental region of the world. In other words, India and southeast Asia.
having more than one female as a mate at one time
rainforests, both temperate and tropical, are dominated by trees often forming a closed canopy with little light reaching the ground. Epiphytes and climbing plants are also abundant. Precipitation is typically not limiting, but may be somewhat seasonal.
reproduction that includes combining the genetic contribution of two individuals, a male and a female
associates with others of its species; forms social groups.
- stores or caches food
places a food item in a special place to be eaten later. Also called "hoarding"

the region of the earth that surrounds the equator, from 23.5 degrees north to 23.5 degrees south.
uses sight to communicate
reproduction in which fertilization and development take place within the female body and the developing embryo derives nourishment from the female.
