An unprecedented influx of Iceland Gulls in the northeastern Atlantic in January/February 2012

摘要

An unprecedented influx of Iceland Gulls Larus glaucoides into northern and northwestern Britain occurred during January and February 2012. That influx is described here, with particular attention to the numbers involved, the age composition of the birds and the occurrence of Kumlien's Gulls L. g. kumlieni. The scale of the influx into Britain & Ireland was dwarfed by that which occurred in the Faroe Islands, and a comparable account for that archipelago is included here.
