Where does the majority of the Sabine’s Gull population establish its wintering range after the northern migration cycle?
The open ocean near the equator in tropical and subtropical seas
The annual rhythm of the Sabine’s Gull involves a dramatic shift from its high-latitude summer nursery to a distinct equatorial winter retreat. Following the breeding season, these birds transition into true pelagic wanderers. Their destination is the open ocean located within the equatorial belt across the world’s major oceans, including the Pacific, Atlantic, and Indian Oceans. During this non-breeding season, the birds are dispersed across vast expanses of open water, often seeking out oceanographic features such as upwellings where invertebrate life is abundant, requiring observers to undertake pelagic trips far from shore.
