Three adult gray whales photographed via drone in 2017, 2018 and 2019 in Laguna San Ignacio off the coast of Mexico. The three shots show increasingly skinny whales, a bad sign for an animal that needs to make a 10,000-mile return trip to reach its feeding grounds.

New Research

Nearly 400 Gray Whales Have Died Off the West Coast Since 2019

Scientists say the die-off, which is entering its third year, is likely due to a scarcity of food in the animals’ cold water feeding grounds
