Which two distant global regions are mentioned as potential wintering grounds for migrating Sabine’s Gulls?
Answer
Coasts of West Africa or waters off South America.
The migratory behavior of adult Sabine’s Gulls is extreme, involving transit across entire hemispheres following the breeding season. Adults departing the Arctic basin utilize two primary oceanic pathways for their wintering grounds. One major route directs them southeast over the Atlantic Ocean, potentially reaching the coasts of West Africa. The alternate route takes them southwest across the Pacific Ocean, leading toward the productive waters off the coast of South America.
