Spotted
The Slaty-backed Gull is a large gull characterized by its dark, slate-grey back and upperwings. It is native to Northeast Asia and is a powerful flier, often seen offshore or along rocky coastlines. This species is known for its hardy nature in harsh northern climates.
Where to spot
Breeds along the coasts and islands of northeastern Asia, including Siberia, Kamchatka, Sakhalin, and the Kuril Islands. Winters south to Japan, Korea, and coastal China. Vagrants sometimes reach Alaska and North America.
How to spot
Look for its very dark slate-grey back and upperwings, contrasting white head and underparts, and pale yellow legs. Distinguish from similar large gulls by the extent of dark plumage and leg color. Observe its powerful, steady flight over water.
When to spot
Best seen during the breeding season (May-July) in its northern range, or during migration and winter (September-March) along the coasts of East Asia. Pelagic trips can offer views of individuals offshore.

This gull often nests on cliffs and rocky islets in remote northern regions, making its breeding colonies difficult to access and study.
