No that is precicsely communication, but nothing indicazes that is "talk". Communication is the "lower" phenomenon ghen talk/speech. Involuntary body processes communicate something in us sapiensapiens and we are sure tjat animals communicate. But do they talk... if we say "talk" ("sprechen") that entails the whole of what natural languages do and is quite different.

Again, reacting when an action is detected does not show communication.

I think you're confused about what the communication is.

The communication isn't the waving in "reaction" (it's not clear it's simply a reaction, but let's assume it is) to the original wave, but the original wave itself.

And the fact that it's also triggered by videos indicates it's not just a mechanical reaction (like some of the research about how plants "communicate" is which are essentially mechanical responses to stimuli).

However, this doesn't necessarily mean that the communication is meaningful. It just shows that a means of communicating exists.

"It just shows that a means of communicating exists."

That is my point. No confusion here.
