Dear MARMAM Colleagues, On behalf of my co-authors, I am delightedto announce the publication of our recent paper: Shabangu FW, Hofmeyr GJG, Probert R, ConnanM, Buhrmann CA, Gridley T. 2022. In-air acoustic repertoire and associatedbehaviour of wild juvenile crabeater seals during rehabilitation. Bioacoustics,https://doi.org/10.1080/09524622.2022.2108145 Abstract In-air sounds of pinnipeds are importantfor interactions with conspecifics and threat displays. However, little isknown about the in-air acoustic repertoire and associated behaviour ofcrabeater seals Lobodon carcinophaga. We investigated the in-airacoustic repertoire and associated behaviour of two male and one female wild juvenilecrabeater seals that beached separately, and were rehabilitated in Durban andGqeberha, South Africa. In-air sounds were visually identified and categorisedinto five classes validated via random forest model classification: brief,intermediate, and long moan calls, croaks, and hisses. Hisses were common (n =25,105 sounds from 136 hrs of acoustic recordings) and detected during heightenedarousal states and interactions with animal care staff and a conspecific.Furthermore, hisses were also recorded in low arousal states during exhalation.Moan calls (n = 241) were only detected from two of the three seals. Duringrehabilitation, the female seal ceased producing moan calls and later produced aseries of croaks (n = 204). Acoustic characteristics of in-air moan callsdiffered from published underwater moan calls according to duration, minimum,and maximum frequencies, and pulse repetition rate. Our study shows that thein-air acoustic repertoire and associated behaviour of these Antarctic sealsare dynamic, vary inter-individually and are context dependent.
