Iceland Gull Larus Glaucoides
Iceland Gull Larus glaucoides Folk Name: (none) Status: Migrant Abundance: Accidental Habitat: Open water of lakes or rivers The Iceland Gull breeds in the Arctic and most spend the winter along the northeastern coast of the United States and Canada. They are rare, but somewhat regular, along the coast of the Carolinas between October and April. They are casual inland. An immature Iceland Gull was seen and well photographed on Lake Norman on March 9, 2014, by several observers in two boats, one captained by David and Marcia Wright and the other captained by Chris Talkington. This sighting represents the first record of this species for both Mecklenburg County and Iredell County, and is also the first and only report of an Iceland Gull in the Central Carolina region. This bird wasn’t an easy find. The birders located the gull after carefully “sifting” through hundreds of other gulls roosting on the lake. Kevin Metcalf noted these field marks: Seemed to be second winter plumage. …Larger than Ring-billed Gulls and smaller than Herring Gull. Washed out whitish gull. Pale gray on back. Primaries whitish with slight brown-gray tint, tail in flight slightly more brown-gray than rump. Bill bi-colored dark at tip, pale base. Eye appeared dark Iceland Gull on Lake Norman.

(369) the Glaucous Gull in Winter
(369) THE GLAUCOUS GULL IN WINTER BY G. T. KAY. (Plates 40-53). SINCE the winter of 1941-42 the Glaucous Gull (Larus hyperboreus) has become a comparatively numerous winter-visitor to the Shet land Islands. At a refuse dump on the outskirts of Lerwick where it had been rare to see more than half a dozen of these birds together, it is now a common occurrence to see thirty or forty and occasion ally as many as a hundred. During the winter of 1945-46, the writer, with others interested in the project, arranged for an attempt to be made to photograph particularly Glaucous Gulls and possibly Iceland Gulls (Larus glaucoides) in the vicinity of the dump. The proposal was to use still and cine cameras from hides. It was hoped that a series of photographs might be secured which would do something towards clearing up the difficulties of dis tinguishing between these two species in the field, which have proved to be in some respects greater than used to be supposed. We were fortunate as regards the Glaucous Gull. A series of photographs and 300ft. of cine film were taken of this arctic visitor at most stages of plumage from the bird in its first winter plumage to that of the fully adult. Further photographs were added during the winter of 1946-47. Unfortunately the only Iceland Gull seen during these two winters was a dead specimen ; an immature bird in its first winter which had been captured on a fishing boat off the east side of Shetland on January 16th, 1947. -

The Herring Gull Complex (Larus Argentatus - Fuscus - Cachinnans) As a Model Group for Recent Holarctic Vertebrate Radiations
The Herring Gull Complex (Larus argentatus - fuscus - cachinnans) as a Model Group for Recent Holarctic Vertebrate Radiations Dorit Liebers-Helbig, Viviane Sternkopf, Andreas J. Helbig{, and Peter de Knijff Abstract Under what circumstances speciation in sexually reproducing animals can occur without geographical disjunction is still controversial. According to the ring species model, a reproductive barrier may arise through “isolation-by-distance” when peripheral populations of a species meet after expanding around some uninhabitable barrier. The classical example for this kind of speciation is the herring gull (Larus argentatus) complex with a circumpolar distribution in the northern hemisphere. An analysis of mitochondrial DNA variation among 21 gull taxa indicated that members of this complex differentiated largely in allopatry following multiple vicariance and long-distance colonization events, not primarily through “isolation-by-distance”. In a recent approach, we applied nuclear intron sequences and AFLP markers to be compared with the mitochondrial phylogeography. These markers served to reconstruct the overall phylogeny of the genus Larus and to test for the apparent biphyletic origin of two species (argentatus, hyperboreus) as well as the unex- pected position of L. marinus within this complex. All three taxa are members of the herring gull radiation but experienced, to a different degree, extensive mitochon- drial introgression through hybridization. The discrepancies between the mitochon- drial gene tree and the taxon phylogeny based on nuclear markers are illustrated. 1 Introduction Ernst Mayr (1942), based on earlier ideas of Stegmann (1934) and Geyr (1938), proposed that reproductive isolation may evolve in a single species through D.

The owls nested in an old (possible corvid) nest in a willow and raised two owlets. They probably did not hunt gulls, neither adults nor chicks. We suggest that, in this case, the Long-eared Owls benefitted from breeding within a gull colony because of the added security against predators that the gulls provided.
