Little is known about the Critically Endangered Eastern South Pacific southern right whale (Chile-Peru Subpopulation) and their movements. In 2012, the IWC adopted a Conservation Management Plan for this population and since 2016 the Scientific Committee has supported a Passive Acoustic Monitoring (PAM) project to facilitate the identification of potential breeding areas along the coast of Chile and Peru. One year of data was successfully collected from southern Chile, and additional data are currently being collected form central Chile. A southern right whale automatic detector is being developed and the first southern right whale calls have been found during December 2019 from the southern Chile site. In the near future, recording at different location sites need to be continued and the automatic detector improved. Additional funding is needed to continue the PAM project at new locations and to finish the data analysis.
