Gray Whales Making a Recovery
The gray whales faced a significant mortality event in 2019, with nearly 700 whales washing up dead along the West Coast. This event led to a drastic drop in population numbers, with estimates ranging from 13,200 to 16,000 individuals. However, researchers have now reported a positive turn as the gray whales are showing signs of recovery, with current population estimates ranging from 17,400 to over 23,000. The recovery is attributed to the resilience of these marine mammals and the rebound of their food supply after a period of shortage.
