For example, in the second line, how he describes how the birds "peck" along the road. This single descriptive word telling what the birds are doing does a lot for the image. Instead of the birds just being there they are "pecking" along the road. Also instead of them being just birds, he calls them hedgerow birds, which is a little more personality to these birds. And then in that same line how the birds don't even acknowledge his walking by, it is hard to not get a sense of the his peacefulness. In the third line when the focus shifts onto the man instead of the birds, Wordsworth describes how the man travels on. "Travels" has so much more of a spiritual feel to it than saying the man was walking down the road. It even creates the possibility of "traveling" as more metaphoric than physical. All of this causes such a crisp visual interpretation of this situation. Already this begins to demonstrate the man's relationship with nature. He seems to belong there, traveling down that road. .
Only the first four lines of this poem utilize physical descriptions. This demonstrates his tendency to drift his attention from the material world towards the more internalized and subjective world. As a result he only touches briefly on the visual image, although he soon strays from the this and quickly evolves to a much more internalized basis. The next several lines of this poem begin to focus on a visual description of the man's internal disposition. This shows how apparent it is that it can be seen as if someone were sitting in a tree watching him pass by, or simply how he is seen by the outside world. This is a very interesting technique which Wordsworth uses here as a transition to go from the physical situation to the man's emotional state of mind. .
His gait, is one expression: every limb, .
His look and bending figure, all bespeak.
A man who does not move with pain, but moves.
With thought.
