Vogelwarte 49: 65-74 Results of a long-term study (10 years) on the population dynamics of the Rock Bunting Emberiza cia L. in a steep vineyard terrace habitat at the Middle Rhine, Germany (Schuphan 1972) were compared with results from studies (8 years) in steep spruce clearance habitats of the east hillside of the Palatine Forest (Pfälzerwald, Germany; Groh 1988) and natural steep rock steppes in the Wallis (Rhone area, Switzerland; Keusch 1991). The aim was to detect habitat differences and habitat dependent influence on population dynamic parameters of these geographically separated Rock Bunting populations. At the Rhine 618 mainly colour ringed Rock Buntings contributed to the results, in the Palatine Forest 157 and at the Rhone 993 Rock Buntings. Large differences between the habitats (vineyards, forest clearances, rock steppes) were obvious as well between the sizes of the territories. These were given at the Rhine and the Palatine Forest by topographical natural borders, in contrast to the Wallis where borders were much more flexible. The differences in size were predetermined in the case of the Palatine Forest by the sizes of the clearances, in the case of the Wallis territories obviously by limitation of initial lepidopteran food supply in spring. The small territories at the Rhine were directly affiliated with high food availability which caused a higher population density. Especially the age structure of the populations showed up considerable differences between Rhine and Wallis, for the Palatine forest no data were present. The optimal food supply, together with year round mild weather conditions affected positively the population at the Rhine. Following the first year 69 % of the M (W 49 %) and than in the second year 42 % (W 23 %) of the pri- marily existing territory residents (100 %) returned. Return quotes in the Wallis were 39 % for the M (W 27 %) and in the next following year for the M 16.7 %. From the demographic distribution pattern resulted for the Rhine population over 10 years a mean age for the M of 2.6 years (n = 103) and for the W of 2.0 years (n = 101); in the Wallis the mean age was determined for 3 breeding periods each for the first period 1.3 years for the M (n = 16), second and third period each 1.7 years (n = 9 and n = 13). About one third of the breeding birds remained at the Rhine during winter in their mild breeding habitat. The rough Palatine hillsides were vacated completely. In the Wallis all breeding birds left the breeding territories. Five abroad recoveries of Rock Buntings from the Middle Rhine (autumn-winter) point all in the direction SW; leading lines could be the Nahe- Moselle valleys. The most faraway recovery was realized near Biarritz (1020 km, West-France). The extinction of the Palatine population after 1990 could obviously be attributed to reforestation and the restrictions for new forest clearances. Rock Buntings in populations adapted to mountain areas like in the Wallis, Black Forest and Palatine Forest, did not colonize their neighbor steep vineyard habitats e.g. in the Alsace and the Palatine Weinstrasse, even these habitats show the typical properties of the Rock Bunting habitats like at the Middle Rhine, Nahe, Moselle, and Ahr. These different preferences of habitat structures must be considered when a well directed advancement of the Rock Bunting in management plans is intended.

  • Historic Changes in Species Composition for a Globally Unique Bird Community Swen C
    www.nature.com/scientificreports OPEN Historic changes in species composition for a globally unique bird community Swen C. Renner 1,2* & Paul J. J. Bates 2,3 Signifcant uncertainties remain of how global change impacts on species richness, relative abundance and species composition. Recently, a discussion emerged on the importance of detecting and understanding long-term fuctuations in species composition and relative abundance and whether deterministic or non-deterministic factors can explain any temporal change. However, currently, one of the main impediments to providing answers to these questions is the relatively short time series of species diversity datasets. Many datasets are limited to 2 years and it is rare for a few decades of data to be available. In addition, long-term data typically has standardization issues from the past and/or the methods are not comparable. We address several of these uncertainties by investigating bird diversity in a globally important mountain ecosystem of the Hkakabo Razi Landscape in northern Myanmar. The study compares bird communities in two periods (pre-1940: 1900–1939 vs. post-2000: 2001–2006). Land-cover classes have been included to provide understanding of their potential role as drivers. While species richness did not change, species composition and relative abundance difered, indicating a signifcant species turn over and hence temporal change. Only 19.2% of bird species occurred during both periods. Land-cover model predictors explained part of the species richness variability but not relative abundance nor species composition changes. The temporal change is likely caused by minimal methodological diferences and partially by land-cover. Species richness, relative abundance and species composition are dynamic phenomena and vary in space and over time1,2.

  • Dokumentation Neuer Vogel-Taxa, 5 – Bericht Für 2009
    Vogelwarte 49, 2011: 85 – 104 © DO-G, IfV, MPG 2011 Dokumentation neuer Vogel-Taxa, 5 – Bericht für 2009 Jochen Martens & Norbert Bahr Martens J & Bahr N 2011: Documentation of new bird taxa, 5. Report for 2009. Vogelwarte 49: 85-104. This report is the fifth one of a series and presents the results of a comprehensive literature screening in search for new bird taxa described in 2009, namely new genera, species and subspecies worldwide. We tracked six genera, six species and six subspecies names new to science which according to the International Code of Zoological Nomenclature were correctly de- scribed. One new family was erected (Pnoepygidae, out of Timaliidae) and two former families (Sylviidae and Timaliidae) were strongly modified. New genera were erected for species or species groups, respectively, of the Accipitridae (two), Tyran- nidae, Furnariidae, Paradoxornithidae and Fringillidae (one each). Five of the new species refer to Passeriformes and one to Non-Passeres, a hummingbird. The distributional areas of the new species often are minute, restricted to remote and difficult to access areas and were hitherto overlooked. In several cases the populations in question were known since long. But only substantial studies of their songs, genetics and/or ecology their remarkable acoustical and genetic or ecological properties (in the case of the new crossbill) led to description of new species. In a zoogeographic context most of the new taxa originate from the Neotropics, followed by Indomalayan and Holarctic regions. The remainder of taxa are scattered over Pacific islands and the Afrotropics. In a taxon sequence by genus/species/ subspecies the newly described taxa have following origin: Neotropis and Caribbean (4/2/3), Palearctic (-/-/1), Indo-Malaya (1/2/2), Nearctic (-/1/-), Afrotropics (-/1/-), Pacific Islands (1/-/-).

This fairly recently opened-up outlier of India (birders have largely visited the region since 2004) quickly rose to birding prominence with regular observations of some very local species known or thought to be there, but also the rediscovery of the extremely local Mishmi (Rusty-throated Wren-Babbler) in 2004 (formerly only known from a handful of specimens), and the headlining discovery of a completely new species, the very distinctive Bugun Liocichla two years later.

  • Biodiversity Surveys of Xe Sap National Protected Area, Lao
    Biodiversity Surveys of Xe Sap National Protected Area Lao PDR 2012 Thomas N.E. Gray, Thomas Calame, Ben Hayes, Martha J. Hurley, Paul H. Nielsen, Vichith Lamxay, Robert J. Timmins, Khamhou Thongsamouth WWF Greater Mekong, Vientiane, Lao PDR, February 2013 1 Executive Summary This report presents the results of the first detailed biodiversity surveys of Xe Sap National Protected Area Salavan and Xekong provinces, Lao PDR since 1999. Between February and June 2012 more than 140 expert field survey days were spent in three ecological distinct areas of Xe Sap: wet evergreen forest in Kaleum district; plateau and montane hill evergreen forest in Ta Ouy and Samouy districts; and pine-grassland savannah in Ta Ouy district. Surveys targeted large mammals, birds, reptiles and amphibians, and flora. The majority of survey effort (>80% of expert field survey days) was within hill evergreen and Ericaceous cloud forest between 1,000 and 1,800 m.a.s.l. in Ta Ouy district, eastern Xe Sap NPA. Xe Sap NPA remains extensively forested and is important for the conservation of representative endemic biodiversity of the Annamite Moist Forest Ecoregion. Including: • Four restricted range bird-species two of which, chestnut-eared Laughingthrush Garrulax konkakinhensis and black-crowned barwing Actinodura sodangorum, are IUCN-listed as Vulnerable. • Evidence of ten globally threatened reptiles and amphibians plus a number of Annamite endemic taxa. • The Annamite endemic confier Pinus dalatensis which is a characteristic and common species within the hill evergreen forests of western Xe Sap. However compared to the late 1990s the populations of almost all threatened large mammals (e.g.
