Vision and Evolution (A Critique of Dawkins)

The phenotype (from Greek phainein, meaning 'to show', and typos, meaning 'type') of an organism is the composite of the organism's observable characteristics or traits, including its morphology or physical form and structure; its developmental processes; its biochemical and physiological properties; its behavior, and the products of behavior

By definition behaviour is part of its phenotype.

My question, broadly speaking, is if you agree with this definition? Behavior is not as quantifiable as other traits, such as color. Neither is cognition as observable as height, for example. I haven't been able to read Dawkins' book The Extended Phenotype, but it seems to be arguing in favor of including behavior and all its repercussions on the world as extensions of what would otherwise be limited by the term phenotype.
