🐋 Help us protect these locals! During peak gray whale migration periods, boaters should remain especially alert and watch carefully for whales in the area. Reducing speed and operating with caution can lower the risk of collisions. If whales are sighted, vessels should maintain a distance of at least 100 yards and avoid approaching, crossing their path, or otherwise altering their natural behavior. Gray whales (Eschrichtius robustus) undertake one of the longest annual migrations of any mammal

Do whales migrate every year? Known as trickle migration, humpback whales steadily trickle into breeding grounds rather than migrating as an entire population before returning to feeding grounds. But, not every whale migrates every year! As migration is energetically costly for humpback whales, some individual whales remain year-round at their feeding grounds. 🩵🐋 📸Research activities authorized under NMFS/MMPA ESA Permit #21321 following all guidelines.
