Description:Southern right whales (SRWs, Eubalaena australis) typically migrate between summer, high-latitude offshore foraging grounds and winter calving grounds located in coastal, temperate waters. Premodern and modern whaling operations nearly extirpated SRWs; the species declined from about 100,000 individuals in the early 1800s to a few hundred individuals around the 1920s (International Whaling Commission [IWC], 2013; Jackson et al., 2008). However, since the protection of the species under the regulations of the International Whaling Commission in 1935 and the end of illegal Soviet whaling (1950s–1970s), SRWs have been recovering steadily in parts of their historical range, particularly in the coastal wintering and calving areas of Argentina, Brazil, South Africa, Australia, and New Zealand (e.g., Best et al., 2001; Carroll et al., 2014; Cooke et al., 2001). Due to their predictable nearshore presence in these regions, they have been extensively studied, with some of the longest photo-identification studies for any cetacean, ongoing since the 1970s (e.g., Bannister, 2001; Best et al., 2001; Payne, 1986). These long-term data sets have provided a wealth of information on population parameters, including calving rates, population size, and trends in abundance (e.g., Bannister, 2001; Brandão et al., 2018; Burnell, 2001, 2008; Carroll et al., 2011; Charlton et al., 2019; Cooke et al., 2001; Stamation et al., 2020; Watson et al., 2021).
