William Walker Peggy H. Ostrom Patrick J. Gould 1997 <p><span>We examined digestive tract contents and nitrogen stable isotope ratios in breast muscles of northern fulmars (<i>Fulmarus glacialis</i>) salvaged from squid and large-mesh drift nets in the transitional North Pacific. Lantern fishes (Myctophidae) were the principal prey item found in the digestive tracts. Pieces of unidentified fishes (probably Pacific pomfret <i>Brama japonica</i>) and shredded squid tissue (probably neon flying squid <i>Ommastrephes bartrami</i>) indicate scavenging at fishing operations. Although soft-bodied prey such as Velella were not found in the digestive tracts, δ </span>¹⁵<span>N values suggest that fulmars may feed heavily on such low trophic-level animals.</span></p> application/pdf 10.2307/3536846 en Society for Northwestern Vertebrate Biology Foods of northern fulmars associated with high-seas drift nets in the transitional region of the North Pacific article
