We studied distribution of seabirds using strip transect counts from May $2^{nd}$ to $30^{th}$, 2011. we observed 322 individuals from nine seabird species. Black-tailed gulls (Larus crassirostris, 48.4%) were numerically dominant. Ancient murrelets (Synthliboramphus antiques, 18.6%), Vega gulls (Larus vegae, 17.7%), red-throated divers (Gavia stellata, 4.7%), Pacific divers (Gavia pacifica, 4.3%), streaked shearwaters (Calonectris leucomelas, 1.9%), and common terns (Sterna hirundo, 1.6%), were also frequently observed. The overall seabird density was 0.55 birds $km^{-2}$, lower that of the East Sea.
