  • Armenian Gulls Larus Armenicus in Egypt, 1989/90, with Notes on the Winter Distribution of the Large Gulls
    A vocetta N° 16: 89-92 (1992) Armenian Gulls Larus armenicus in Egypt, 1989/90, with notes on the winter distribution of the large gulls PETER L. MEININGER* and UFFE GJ0L S0RENSEN** * Foundation for Ornithological Research in Egypt, Belfort 7, 4336 JK Middelburg, Netherlands ** Mellegade 21, J t. V., DK-2200 Copenhagen, Denmark Abstract - During a survey of Egyptian wetlands between December 1989 and late May 1990 significant numbers of Armenian Gulls Larus armenicus were observed. Total winter count was 442, and the species was present until early April , It was found to be relatively common along the Mediterranean coast east of the Damietta branch of the Nile, and in marine habitats of the three lagoons along this coast. Small numbers were seen along the Suez Canal and the Red Sea coast. No Armenian Gulls were found in any of the inland waters. Other large gulls counted in winter included Yellow-Iegged Gulls L. cachinnans (2340), Lesser Black-backed Gulls L. fuscus (120; including the first Egyptian record of L. f. heuglini), and Great Black-headed Gulls L. ichthyaetus (35). Introduction pitfalls, observations made during this project revealed the presence of considerable numbers of The Armenian Gull Larus armenicus is known from Armenian Gulls in Egypt. This paper summarizes a restricted breeding area in high altitude lakes of the observations of Armenian Gulls in Egypt in Armenia (Lake Sevan, Lake Arpa), Iran (Lake 1989/90. In addition some information is presented Uromiyeh), eastern Turkey (Van Gòlu), and at least on the winter distribution of other large gull species. one locality (Tuz Gòlù) in Centrai Anatolia in The systematic position of the Armenian Gull is one Turkey (Suter 1990).

  • Species Boundaries in the Herring and Lesser Black-Backed Gull Complex J
    Species boundaries in the Herring and Lesser Black-backed Gull complex J. Martin Collinson, David T. Parkin, Alan G. Knox, George Sangster and Lars Svensson Caspian Gull David Quinn ABSTRACT The BOURC Taxonomic Sub-committee (TSC) recently published recommendations for the taxonomy of the Herring Gull and Lesser Black-backed Gull complex (Sangster et al. 2007). Six species were recognised: Herring Gull Larus argentatus, Lesser Black-backed Gull L. fuscus, Caspian Gull L. cachinnans,Yellow-legged Gull L. michahellis, Armenian Gull L. armenicus and American Herring Gull L. smithsonianus.This paper reviews the evidence underlying these decisions and highlights some of the areas of uncertainty. 340 © British Birds 101 • July 2008 • 340–363 Herring Gull taxonomy We dedicate this paper to the memory of Andreas Helbig, our former colleague on the BOURC Taxonomic Sub-committee. He was a fine scientist who, in addition to leading the development of the BOU’s taxonomic Guidelines, made significant contributions to our understanding of the evolutionary history of Palearctic birds, especially chiffchaffs and Sylvia warblers. He directed one of the major research programmes into the evolution of the Herring Gull complex. His tragic death, in 2005, leaves a gap in European ornithology that is hard to fill. Introduction taimyrensis is discussed in detail below, and the Until recently, the Herring Gull Larus argentatus name is used in this paper to describe the birds was treated by BOU as a polytypic species, with breeding from the Ob River east to the at least 12 subspecies: argentatus, argenteus, Khatanga (Vaurie 1965). There has been no heuglini, taimyrensis, vegae, smithsonianus, molecular work comparing the similar and atlantis, michahellis, armenicus, cachinnans, intergrading taxa argentatus and argenteus barabensis and mongolicus (Vaurie 1965; BOU directly and any reference to ‘argentatus’ in this 1971; Grant 1986; fig.

Monzikov Martin Elliott ABSTRACT Between 19th July and 1st August 1997, at the Chany Lakes in southwestern Siberia, data were collected on phenotype features and behaviour of the local populations of gulls Larus belonging to the taxonomically vague form barabensis.These were compared with data from the literature and museum material on the morphological, oological and behavioural characters of L. c. cachinnans and L. (fuscus?) heuglini, as well as those of some other related gull forms. In size, proportions and coloration, barabensis most closely resembles heuglini, while also showing © British Birds 93: 227-241, May 2000 227 Panov & Monzikov: Status of the form barabensis some admixture of cachinnans characters.The authors conclude that barabensis is a well-defined taxon that has arisen as a result of introgression by cachinnans genes into heuglini populations as the latter expanded their range southwards.They suggest that barabensis be treated as a subspecies of L. heuglini unless the latter’s status as specifically distinct from Lesser Black-backed Gull L. fuscus is proven to be unwarranted. he various forms of large gull Larus recent reviews of the Russian avifauna, that breed in Europe and, particularly, barabensis is not accepted as a valid race, on TAsia have for some time been a source the grounds that it is not sufficiently distinct of much confusion among taxonomists. from such taxa as taimyrensis or nominate Traditionally, they have been treated as sub- cachinnans (Stepanyan 1975; Yudin & species of the Herring Gull L.

Green Bee-eater. One of the iconic birds of southern Israel. This was Tropical Birding’s inaugural Israel tour but guide Trevor Ellery had previously lived, birded and guided there between 1998 and 2001, so it was something of a trip down memory lane for the guide! While Israel frequently makes the international news due to ongoing tensions within the country, such problems are generally concentrated around specific flashpoints and much of the rest of the country is calm, peaceful, clean and modern. www.tropicalbirding.com +1-409-515-9110 [email protected] Tropical Birding Trip Report Israel March, 2018 Our tour started on the afternoon of the 10th where, after picking up the group at Ben Gurion airport near Tel Aviv, we headed north along the coastal strip, collecting our local guide (excellent Israeli birder Chen Rozen) and arrived at Kibbutz Nasholim on the shores of the Mediterranean with plenty of time for some local birding in the nearby fishponds. Spur-winged Lapwing – an abundant, aggressive but nevertheless handsome species wherever we went in Israel. Hoopoe, a common resident, summer migrant and winter visitor. We saw this species on numerous days during the tour but probably most interesting were quite a few birds seen clearly in active migration, crossing the desolate deserts of the south. www.tropicalbirding.com +1-409-515-9110 [email protected] Tropical Birding Trip Report Israel March, 2018 We soon managed to rack up a good list of the commoner species of these habitats.

Introduction This document constitutes the official 2015 AERC TAC recommendations for species-level systematics and nomenclature of Western Palearctic birds. For full information on the TAC and its history, please refer to the documents on the AERC web page www.aerc.eu, including the minutes of the AERC meetings http://www.aerc.eu/minutes.html and the TAC pages www.aerc.eu/tac.html. The format of this document follows the previous TAC recommendations (Crochet et al. 2010), which see for details. The TAC has five members: Taxonomic Sub-committee of the British Ornithologists’ Union Records Committee (BOURC-TSC, UK), Commission de l’Avifaune Française (CAF, France), Swedish Taxonomic Committee (STC, Sweden), Commissie Systematiek Nederlandse Avifauna (CSNA, Netherlands) and Kommission Artenliste der Vögel Deutschlands der Deutschen Ornithologen-Gesellschaft (German TC, Germany). As decided previously, systematic changes are based on decisions published by, or directly passed to the TAC chairman, by these taxonomic committees (TCs). In this document, the support for each case is given as yes / no / not addressed.
