Evidence

Preprint

Geography

Pará, Brazilian Amazon

System

Tropical forest restoration landscape

## WHAT THE EVIDENCE SAYS

Researchers validated 995 acoustic detections from 8,940 hours of recording and confirmed about 43% of threatened bird species considered possible in the region, including five first site confirmations. The workflow outperformed traditional surveys for detection in this case.

## WHY IT MATTERS / OUR READ

The interesting signal is not autonomous monitoring; it is a scalable triage system in which machine classifiers expand search effort while experts remain central to validating rare-species detections.

## CAVEATS / UNCERTAINTY

This is a preprint using a beta classifier. Reliability varied among species, validation effort was substantial, and the study could not determine whether restoration itself caused the detected occurrences.
