Data Shows which Orcas are Most at Home in Puget Sound

Data spanning nearly half a century shows that endangered Southern Resident orcas are spending less time in inland waters, whereas their larger cousins, Bigg’s killer whales, are increasingly present in Puget Sound.

Researchers found that Southern Resident K and L pods are visiting Puget Sound less often, but the J pod remains well represented. The data on Bigg’s corroborates recent results showing a steady increase in inland waters.
