Gray whales begin to leave their northern Pacific feeding grounds in the fall, migrating upwards of 6,000 miles south along the coastline to breed and calve in Baja California, Mexico. They begin their return migration in late winter/early spring, traveling as much as 12,000 miles round trip, one of the longest migrations of any mammal! 🐋 Adult gray whale & calf 📍 Laguna San Ignacio, BCS 🎥 @slatermoorephotography #OceanicSociety #TravelForGood #Ecotourism #SustainableTourism #NatureTravel #NatureTourism
