Comment on "Dolphin and porpoise detections by the F-POD are not independent: Implications for sympatric species monitoring" [JASA Express Lett. 4, 031202 (2024)].

Abstract

Dolphin and porpoise detections by the F-POD are not independent: Implications for sympatric species monitoring, Cosentino, Marcolin, Griffiths, Sánchez-Camí, and Tougaard [(2024). JASA Express Lett. 4, 031202] address a significant issue, the reliability of the discrimination of dolphins and porpoises in recordings of their acoustic clicks by F-POD loggers, but unfortunately present a misleading interpretation of the process and results. The issues raised are already stated in a published description of the relevant KERNO-F classifier. We hope this response will clarify both the acoustic issues and how they can be best addressed.
