The Newport Chapter of the Surfrider Foundation will present a free virtual program called “Do gray whales count calories?” this Thursday, from 6:30 to 8 p.m.
Predators must consume enough prey to support costly events, such as reproduction and migration. Meeting high energetic requirements is particularly challenging for migrating baleen whales as their feeding seasons are typically restricted to a limited temporal window and marine prey are notoriously patchy.
This talk, presented by Lisa Hildebrand, Ph.D. student and marine mammal institute graduate fellow at Oregon State University, discusses the potential role that prey quality has in driving the discrepancy of population/group sizes of gray whales across two different foraging grounds in the eastern North Pacific, and how differences in prey caloric content affects decision-making of foraging gray whales along the Oregon coast.
