ABSTRACT
Some Discourse models are shared widely across many Discourses, some are not. My Discourse model (really a connected set of models) of how avid bird watchers behave, act, interact, and value has been built out of my experiences with birders, though from the periphery of the Discourse (I am not a "real" birder), and is probably not shared in any great degree with non-birders. And, by the way, if you don't think bird watchers constitute a Discourse, read Mark Cocker's book Birders: Tales if a Tribe (2001) and you will quickly realize that birders enact and recognize distinctive social identities and activities.
