AbstractFatty acid and alcohol components of preen oil were determined in three gull species that belong to two sys-tematic genera: herring gullLarusargentatus, common gullLaruscanusand black-headed gullChroicocephalusridibundus. All gulls were captured in winter, in Gdańsk, Poland. All gulls produced monoesters composed ofC7–C16saturatedfattyacidsandC11–C20saturatedalcohols,withn-octanoicacidandn-hexadecanolasthemajorfatty acid and alcohol, respectively. Preen oils of black-headed gull had higher content of trimethyl fatty acids,2,8-dimethylundecanoic acid, 2,6-dimethylundecanoic acid and 2,6-dimethylnonanoic acid, and lower contentof2-methylfattyacidsthanoilsofherringgullandcommongull.Preenoilsproducedbyblack-headedgullalsohadlowercontentof2-methylalcohols.Therelativecontentsofn-octanoicacidandn-hexadecanoldidnotdifferamong species. The differences among species are probably not a result of different diet, as all gulls fed mainlyonhouseholdrefuse.Hence,preenoilanalysisconfirmedthetaxonomicrelationsamongthesegullspecies,thatrecently were placed into two different genera.
