Biology     Glossary (e.g. epibenthic)

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). Breeding is asynchronous, with breeding periods of different birds overlap to varying degrees (Ref. 93225).
