The world's only night-feeding gull; It pursuits squid and nocturnal fish at open sea (Ref. 356). Breeding attempts occur between migration events (Ref. 93225). It feeds by surface plunging, having access to only 1 meter of the water column (Ref. 93225), and feeds between 16-32 km from coastline (Ref. 356). Foraging activity increases following the DVM cycle, during new moon periods (Ref. 93225).
