average 212 lbs. (about the weight of a large man)

Where they live:
Mule Deer occurs over most of North America west of the 100th meridian from 23 degrees to 60 degrees N. The eastern edge of the usual range extends from southwestern Saskatchewan through central North and South Dakota, Nebraska, Kansas, and western Texas.

Mule Deer are found throughout Washington, including the islands, in hardwood and coniferous forests, dense shrubs or other growth stages with small trees or shrubs. They are also found in meadows, and grasslands, including alpine meadows, near forest. The availability of browse in forest understory is important for them.

What they eat: Mule Deer are herbivores; they browse or graze depending on the season. They feed on a variety of vegetation including green plants, nuts and corn, and trees and twigs. They like to browse on Douglas fir and Ponderosa pine.

Behavior:

The Mule Deer carries its thin, black-tipped tail drooped, unlike the uplifted, bushy white tail of its cousin.

Mule Deer have large ears that move constantly and independently, from whence they get their name, "Mule" or "Burro Deer." They do not run as other deer, but have a distinctive bounding leap (stotting) over distances up to 8 yards, with all 4 feet coming down together. In this fashion, they can reach a speed of 45 m.p.h. for short periods. (DesertUSA.com)
