    BUCKBIRD JOURNEYS YEMEN and SOCOTRA Tuesday 8 – Sunday 18 November 2007 Participants Louise Augustine (LA), Hugh Buck (HB), David Daniels (DD), David Hoddinott (DH), Pearl Jordan (PJ), Werner Suter (WS), David Bradford (DB – Socotra only) This trip was designed to try for all the Southwest Arabia and Socotra endemics in a relatively brief time scale. It also represented an opportunity for regional listers to add an enticing selection of “African” species only entering Asia in Southwest Arabia and a selection of “Asian” species found in Africa rarely outside of Socotra. That the trip was successful on all counts is a tribute to Yousuf Mohageb (YM) of Arabian Eco- Tours in Sana’a who designed, with HB, the itinerary, accompanied us throughout Yemen and knew all the best birding spots, Ali his redoubtable co-driver and Ahmed Saeid Suliman (AS) on Socotra whose knowledge and love of all things on his island home is second to none. Our multinational group (three Americans, two Brits, a South African and a Swiss) kept to the pace admirably, provided exceptional spotting skills and, in WS, some wonderful photographic documentation and memories. Day by Day Thursday 8 November HB, DD and DH meet up at Dubai International Airport for the short Emirates Airlines flight to Sana’a where they are met by YM, Ali in traditional Yemeni costume and LA and PJ who have arrived the previous evening. Under the high bright sun, which will be the norm for the next 10 days, we traverse Sana’a’s sprawling outskirts to the Funduk Arabia Felix, an interesting hotel made up a several old traditional houses right at the edge of the historic and UNESCO rated old town.

    The Ornithological Society of the Middle East, the Caucasus and Central Asia (OSME) The OSME Region List of Bird Taxa, Part F: Simplified OSME Region List (SORL) version 5.1 August 2019. (Aligns with ORL 5.1 July 2019) The simplified OSME list of preferred English & scientific names of all taxa recorded in the OSME region derives from the formal OSME Region List (ORL); see www.osme.org. It is not a taxonomic authority, but is intended to be a useful quick reference. It may be helpful in preparing informal checklists or writing articles on birds of the region. The taxonomic sequence & the scientific names in the SORL largely follow the International Ornithological Congress (IOC) List at www.worldbirdnames.org. We have departed from this source when new research has revealed new understanding or when we have decided that other English names are more appropriate for the OSME Region. The English names in the SORL include many informal names as denoted thus '…' in the ORL. The SORL uses subspecific names where useful; eg where diagnosable populations appear to be approaching species status or are species whose subspecies might be elevated to full species (indicated by round brackets in scientific names); for now, we remain neutral on the precise status - species or subspecies - of such taxa. Future research may amend or contradict our presentation of the SORL; such changes will be incorporated in succeeding SORL versions. This checklist was devised and prepared by AbdulRahman al Sirhan, Steve Preddy and Mike Blair on behalf of OSME Council. Please address any queries to [email protected].

    ABBA Form 2 (3/11) LIST OF THE BREEDING BIRDS OF ARABIA (Please note this list, including the nomenclature and taxonomic order is under review and will be bought in line with that of the Atlas of the Breeding Birds of Arabia which was published in July 2010. Also the status notes do not in all cases reflect the up to date situation. This is also being reviewed). The species listed here are those known to have bred in Arabia or are very likely to breed. The order follows the List of recent Holarctic bird species by K. H. Voous (published by the British Ornithologists Union, 1977) but certain changes have been made to bird names to accord with present usage. The reference number shown on the left is the number to be inserted in Column 2 of the ABBA Report sheet Form 3. The few breeding species not on the Voous list (these are mainly ferally breeding exotics) are given a separate sequence commencing with 2001. The Breeding Evidence Code (BEC) used by the ABBA project should be read in conjunction with this list. Details of species additional to the list, for which breeding is proven (BEC 10 or higher), will be published in future issues of Phoenix. Observers suspecting or proving breeding of species not shown on the list should make a full report. Highly sedentary species are identified with an asterisk (*). Because presence of these species, even outside the breeding season, is a good indication of local breeding. BEC "XX" may be used to report occurrence in suitable habitat at any time.

It is therefore fitting that in 2001 the Kingdom of Saudi Arabia became a signatory to the Convention on Biological Diversity that seeks to ensure the conservation of species and their habitats for all time. Biodiversity is itself a complex resource, but it differs from many other natural resources in that it is managed at local levels, but is subject to claims and influences that may operate on a global scale. Consequently, successful conservation of biodiversity requires involvement of all stakeholders, from the smallest local communities to the global community. It is this that makes the Convention on Biological Diversity so important.

  • Ranking and Mapping the High Conservation Priority Bird Species of Saudi Arabia
    VOLUME 15, ISSUE 2, ARTICLE 18 Boland, C. R. J., and B. O. Burwell. 2020. Ranking and mapping the high conservation priority bird species of Saudi Arabia. Avian Conservation and Ecology 15(2):18. https://doi.org/10.5751/ACE-01705-150218 Copyright © 2020 by the author(s). Published here under license by the Resilience Alliance. Research Paper Ranking and mapping the high conservation priority bird species of Saudi Arabia Christopher R. J. Boland 1 and Bruce O. Burwell 2 1Environmental Protection Department, Saudi Aramco, 2Operational Excellence Department, Saudi Aramco ABSTRACT. One of the challenges facing conservation biologists and land managers is to determine which species in the biota should receive conservation priority. This is particularly challenging in regions with comparatively little baseline ecological data, such as the Arabian Peninsula. Here we create a list of high conservation priority species for the birds of Saudi Arabia using objective criteria. In total, 102 of Saudi Arabia’s 401 regularly occurring bird species were assigned as high conservation priority. We then rank the conservation priority of these species based on their threatened status, population trend, national distribution and abundance, level of national responsibility, endemicity, and evolutionary distinctiveness. We use GIS to map the locations of high conservation priority species, revealing that most occur in the Kingdom’s southwest (in the Asir Mountains and foothills, Tihama coastal plains, and Red Sea coastline). A wide array of threats is impacting Saudi Arabia’s highest conservation priority birds, particularly overhunting, alpine habitat fragmentation and degradation, Allee effects, secondary poisoning, and persecution. The methodology that we developed could be easily applied to other taxa and in other countries to help identify and rank high conservation species in other regions with limited baseline data.
