Short-finned pilot whales are deep-water hunters that follow squid into offshore canyons, so their California records trace back to boat surveys and strandings rather than to any of the places listed for them here. Sierra Nevada, Los Padres National Forest, and the Central Valley are all landlocked, and they have nothing to do with a pelagic dolphin. That mismatch is worth naming plainly instead of repeating it as real habitat.

Of the 92 California records, all but 2 came through GBIF rather than iNaturalist, a split that points to stranding reports and offshore survey data instead of casual sightings from a boat deck. Pods this species travels in are hard to approach and photograph, so the lopsided count says more about how the species gets documented than about how often it passes through California waters.

January carries the most records in the monthly count, with a smaller rise late in the year. A single pod encountered near shore, or one stranding event, can easily produce that kind of spike, so it isn’t a reliable migration signal.
