ornitholestes' languages

I've been reading Stephen Baxter's "Evolution", and in his Ch 2, he introduces
the ornitholestes-who-can-talk.

The language is described as such:
	"Hunting carnivores were accustomed to working silently.  So their language
was a composite of soft clicks, hand signals and a ducking body posture - no
facial expressions, for the faces of these orniths were as rigid as any
dinosaurs."

I was just wondering if anyone's done any work on this sort of language
system?

Thanks
