5.4. Changes in the Bird Communities of Sierra Nevada Zamora ,R.1 and Barea-Azcón, J.M.2 1 Andalusian Institute for Earth System Research
5.4. Changes in the bird communities of Sierra Nevada Zamora ,R.1 and Barea-Azcón, J.M.2 1 Andalusian Institute for Earth System Research. University of Granada 2 Environment and Water Agency of Andalusia Abstract The changes in the composition and abundance of passerine communities were studied along an elevational gradient, comparing the results found by censuses made in three different habitats (oak forest, high-mountain juniper scrublands, and high-mountain summits) at the beginning of the 1980s and at present. The results indicate that in the last 30 years, notable changes have taken place in the composition and, especially, in the abundance of the passerine communities. Significant declines in populations were appreciated in many of the species that were dominant in the 1980s, particularly in oak forests and in high-mountain juniper scrublands. The magnitude of the changes diminishes with elevation, and therefore the ecosystem that has changed the most was the oak woodland and those that changed the least were the ecosystems of the high-summits. The bird communities in Sierra Nevada showed a strong spatio-temporal dynamic that appears to be accentuated by global change. Aims and methodology The censuses of reproductive birds compiled censuses were made along linear transects with [13 - 17]. The current censuses were undertaken at the beginning of the 1980s and at present a fixed bandwidth of 50 m, 25 m on each side of within the framework of the Sierra Nevada (2008-2012) were compared. The sites studied the observer. The sampling effort was similar in Global Change Observatory from 2008 to 2012, were the same in both periods: an oak forest both periods. -

Senescense and Dispersal Under Local Climatic Variations of Bearded Reedlings Panurus Biarmicus at the Southwestern Limit of Their European Distributional Range

Whooper Swan
Whooper Swan The Whooper Swan (Cygnus cygnus), pronounced hooper swan, is a large Northern Hemisphere swan. It is the Eurasian counterpart of the North American Trumpeter Swan, and the type species for the genus Cygnus. Francis Willughby and John Ray's Ornithology of 1676 referred to this swan as "the Elk, Hooper, or wild Swan". The scientific name is from cygnus, the Latin for "swan". The Whooper Swan is similar in appearance to the Bewick's Swan. It is larger, however, at a length of 140–165 cm (55–65 in) and a wingspan of 205–275 cm (81–108 in). It is considered to be amongst the heaviest flying birds. It has a more angular head shape and a more variable bill pattern that always shows more yellow than black (Bewick's Swans have more black than yellow). Like their close relatives, Whooper Swans are vocal birds with a call similar to the Trumpeter Swan. Despite their size Whooper Swans are powerful fliers and can migrate hundreds or even thousands of miles to their wintering sites in southern Europe and eastern Asia. They breed in subarctic Eurasia, further south than Bewick’s in the taiga zone. They are rare breeders in northern Scotland, particularly in Orkney, and no more than five pairs have bred there in recent years; a handful of pairs have also bred in Ireland in recent years. This bird is an occasional vagrant to the Indian Subcontinent and western North America. Icelandic breeders overwinter in the United Kingdom and Ireland, especially in the wildfowl nature reserves of the RSPB and of the Wildfowl and Wetlands Trust. -
Thick-Billed Warbler (Iduna Aedon) at Gambell, Alaska: First Record for North America Gary H
NOTES THICK-BILLED WARBLER (IDUNA AEDON) AT GAMBELL, ALASKA: FIRST RECORD FOR NORTH AMERICA GARY H. ROSENBERG, 8101 North Wheatfield Dr., Tucson, Arizona 85741; [email protected] PAUL E. LEHMAN, 11192 Portobelo Dr., San Diego, California 92124; [email protected] AARON J. LANG, 40208 Alpenglow Circle, Homer, Alaska 99603; [email protected] VICTOR AND RUBEN STOLL, 899 Miller Rd., Centerville, Tennessee 37033; [email protected] In the evening on 8 September 2017, in the “far boneyard” at Gambell, St. Law- rence Island, Alaska (63.78° N, 171.74° W), Victor and Ruben Stoll flushed a pas- serine they could not immediately identify. The “boneyards” are large pits excavated by the resident Yupik Natives seeking buried ivory and artifacts, a result of several thousand years of sea-mammal hunting from this island’s Northwest Cape. Working these pits turns the soil, which has resulted in the growth of relatively lush vegetation consisting of two species of Artemisia, known locally as “wormwood.” The combina- tion of lush vegetation (reaching 0.5–1 m in height) and deep depressions that offer protection from the wind is attractive to migrant and vagrant landbirds in the otherwise flat, gravelly landscape. Soon thereafter, we, along with Greg Scyphers, Monte Taylor, and other birders then at Gambell, converged at the far boneyard in search of the bird. It was soon relocated and seen on the ground briefly by Lang, who suggested it was a Thick-billed Warbler (Iduna aedon), a bird he was familiar with from southeastern Asia and a species not previously recorded in Alaska or North America. -

Based on Nuclear and Mitochondrial Sequence Data
MOLECULAR PHYLOGENETICS AND EVOLUTION Molecular Phylogenetics and Evolution 29 (2003) 126–138 www.elsevier.com/locate/ympev Phylogeny of Passerida (Aves: Passeriformes) based on nuclear and mitochondrial sequence data Per G.P. Ericsona,* and Ulf S. Johanssona,b a Department of Vertebrate Zoology and Molecular Systematics Laboratory, Swedish Museum of Natural History, Frescativagen 44, P.O. Box 50007, SE-10405 Stockholm, Sweden b Department of Zoology, University of Stockholm, SE-106 91 Stockholm, Sweden Received 18 September 2002; revised 23 January 2003 Abstract Passerida is a monophyletic group of oscine passerines that includes almost 3500 species (about 36%) of all bird species in the world. The current understanding of higher-level relationships within Passerida is based on DNA–DNA hybridizations [C.G. Sibley, J.E. Ahlquist, Phylogeny and Classification of Birds, 1990, Yale University Press, New Haven, CT]. Our results are based on analyses of 3130 aligned nucleotide sequence data obtained from 48 ingroup and 13 outgroup genera. Three nuclear genes were sequenced: c-myc (498–510 bp), RAG-1 (930 bp), and myoglobin (693–722 bp), as well one mitochondrial gene; cytochrome b (879 bp). The data were analysed by parsimony, maximum-likelihood, and Bayesian inference. The African rockfowl and rock- jumper are found to constitute the deepest branch within Passerida, but relationships among the other taxa are poorly resolved— only four major clades receive statistical support. One clade corresponds to Passeroidea of [C.G. Sibley, B.L. Monroe, Distribution and Taxonomy of Birds of the World, 1990, Yale University Press, New Haven, CT] and includes, e.g., flowerpeckers, sunbirds, accentors, weavers, estrilds, wagtails, finches, and sparrows. -

The effect of fire on organisms, particularly birds, depend on the extent and regime of the fire and the species’ ecology. The Azure-winged Magpie, Cyanopica cyanus is a cooperative breeder, and occurs in a disjunct distribution across much of Asia and in Iberia (Portugal and Spain). -
