To those who have never seen them in the wild, Kangaroos have excellent camoflauge. The colour of their coat, in addition to their behavioual adaptaion of remianing silent and still helps them look almost indistinguishable from trees and/or tree stumps.

With the acknowledgment that Australia has no large native predators. (Beleive it or not)

What selective pressures forced the kangaroo to have such good camouflage abilities?
(The dingo has been proved to be an introduced species from just over 1000 years ago.)

Not most, but enough to warrant camo.
