Bivalves (mainly <i>Mytilus edulis</i>) were the most frequently occurring food item in all three periods. Gastropods (chiefly <i>Littorina</i> spec.) and crustaceans (mainly <i>Carcinus maenas</i>) were following next. Stones and different types of plant material were also quite frequently present in the pellets. Differences between the three periods were not very marked. Crustaceans, algae, grass and stones were most abundantly found in the cold winter. Oligochaetes occurred only in spring. Stones were quite common in the pellets both by frequency and by mass. In the cold winter 1996, mean stone mass comprised 47% of total pellet mass. It is concluded that Herring Gulls did not alter their diet in the cold winter to a major extent.","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"Herring Gull <i>Larus argentatus</i> winter diet at the western Baltic Sea coast: does ice cover make a difference?","OrigTitleLangCode":"en","OrigTitleLangCodeExtended":"eng","OrigTitleLangID":15,"DateLastModified":{"date":"2025-07-02 08:33:14.980000","timezone_type":1,"timezone":"+00:00"},"UserAccessRight":null,"UserAccID":null,"AuthorKeywords":null,"OtherDescriptors":"Herring gull","Notes":null,"AnaPub":2003,"MonPub":null,"DateUpdate":"2017-09-06","DateCreate":"2003-09-16","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":null,"VABBcode":null,"OpenAcc":1},"refs":null,"anarec":{"AnaID":39406,"PubliDate":2003,"Pagination":"13-20","XtraPublOfAnaID":null,"ISBN":null,"Volume":"5","Issue":"1","BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":45223,"SerRR":"Atlantic Seabirds.
