Globally, warming oceans are causing marine species to shift poleward (Melbourne-Thomas et al., 2022). The Antarctic Peninsula is a global hotspot for human-induced warming (Jones et al., 2019;Turner et al., 2020), evidenced by lessening sea ice conditions (Kumar et al., 2021), warming oceans, and the collapse of ice shelves (Etourneau et al., 2019). Warming is influencing the spatiotemporal occurrence of prey species such as Antarctic krill (Euphausia superba; Kawaguchi & Nicol, 2020), which is, in turn, influencing the foraging behaviors and demographic success of some Southern Ocean predators, e.g., crabeater seals (Erignathus barbatus; Hückstädt et al., 2020). For highly mobile marine predators, such as baleen whales, which are free from range restrictions faced by central place foragers (Orians, 1979), foraging is thought to be directly dictated by finding and accessing profitable prey patches, likely driven by the underlying environmental conditions (e.g., sea ice and chlorophyll concentrations; Bedriñana-Romano et al., 2022;Meynecke et al., 2021;Reisinger et al., 2021). There is some recent evidence that humpback whale (Megaptera novaeangliae) foraging activities have shifted southward in response to record lows in sea-ice extent and presumably spatial shifts in krill populations (
