Resident orcas rarely visit Hood Canal today, but it was an important part of their habitat in the past.
In recent years, Hood Canal is more often visited by transient orcas, drawn by the abundant seal population.
- In 2005, a group of transient orcas entered Hood Canal, and stayed there for almost 3 months. During that time, they were frequently observed from the north tidal area at Dosewallips. Most likely, they were attracted by the seals in the rookery at the rivermouth.
- Researchers estimate that the Hood Canal seal population went down by 50% during the transients' stay.
