What we reviewed · Initial source note

Primary study summary in founding audit; full-text methods review pending.

Not yet independently reviewed by a scientific specialist.

What this does — and doesn’t — establish

A single event offers a valuable observation, but cannot establish a general call dictionary or causal interpretation.

What we can build on

Attach synchronized behavioral context to sound, and retain the event as the unit of analysis.

The next reading task

Identify which interpretations could be tested in independent events.
