CHU Department of Biology and Museum of Zoology The University of Michigan, Ann Arbor, MI 48109 Abstract. Strauch’s (1978) compatibility analysisof relationshipsamong the shorebirds (Charadriifonnes) was the first study to examine the full range of charadriifonn taxa in a reproducibleway. SubsequentlyMickevich and Parenti (1980) leveled seriouscharges against Strauch’s characters,method of phylogenetic inference, and results. To account for these charges,Strauch ’s characterswere re-examined and recoded, and parsimony analyseswere performed on the revised matrix. A parsimony analysison 74 taxa from the revised matrix yielded 855 shortesttrees, each length = 286 and consistencyindex = 0.385. In each shortest tree there were two major lineages,a lineageof sandpiper-likebirds and a lineageof plover- like birds; the two formed a monophyletic group, with the auks (Alcidae) being that group’s sister taxon. The shortest trees were then compared with other estimates of shorebird re- lationships, comparison suggestingthat the chargesagainst Strauch’s results may have re- sulted from the Mickevich and Parenti decisions to exclude much of Strauch’s character evidence.

  • Proposal for the Inclusion of Species on the Appendices of the Convention on the Conservation of Migratory Species of Wild Animals
    1 / 2 Proposal II/7 PROPOSAL FOR THE INCLUSION OF SPECIES ON THE APPENDICES OF THE CONVENTION ON THE CONSERVATION OF MIGRATORY SPECIES OF WILD ANIMALS A. PROPOSAL: Listing the entire population of Glareola nuchalis on Appendix II. B. PROPONENT: Government of Kenya. C. SUPPORTING STATEMENT: 1. Taxon: 1.1 Class: Aves 1.2 Order: Charadriiformes 1.3 Family: Glareolidae 1.4 Genus/species/subspecies: Glareola nuchalis 1.5 Common names: English: Rock Pratincole, White-collared Pratincole French: Glarède aureole 2. Biological data 2.1 Distribution Distributed in West and central Africa. Scarce in eastern Africa. 2.2 Population No detailed census data available, but the best guess information available puts the number at >25,000 within its distribution range. 2.3 Habitat Exposed rocks in large rivers and streams used for breeding. May rest on sandbars, when rivers flood. Also found in coastal localities and other inland waters. 2.4 Migrations Locally common resident and regular intra-African migrant. Migrates within its distribution range. Most post breeding dispersal occurs during the wet season. 3. Threat data 3.1 Direct threats Unpredictable fluctuations of water levels of local rivers during breeding seasons affect the breeding performance. Sand mining along rivers has severe impacts on the availability of suitable habitats in the riparian areas for nesting. 3.2 Habitat destruction Riparian land use activities within the range states limits the availability of suitable roosting and nesting areas along rivers. 3.3 Indirect threats The loss and degradation of catchments for all wetlands within its range. 3.4 Threats connected especially with migrations None known.

  • Disaggregation of Bird Families Listed on Cms Appendix Ii
    Convention on the Conservation of Migratory Species of Wild Animals 2nd Meeting of the Sessional Committee of the CMS Scientific Council (ScC-SC2) Bonn, Germany, 10 – 14 July 2017 UNEP/CMS/ScC-SC2/Inf.3 DISAGGREGATION OF BIRD FAMILIES LISTED ON CMS APPENDIX II (Prepared by the Appointed Councillors for Birds) Summary: The first meeting of the Sessional Committee of the Scientific Council identified the adoption of a new standard reference for avian taxonomy as an opportunity to disaggregate the higher-level taxa listed on Appendix II and to identify those that are considered to be migratory species and that have an unfavourable conservation status. The current paper presents an initial analysis of the higher-level disaggregation using the Handbook of the Birds of the World/BirdLife International Illustrated Checklist of the Birds of the World Volumes 1 and 2 taxonomy, and identifies the challenges in completing the analysis to identify all of the migratory species and the corresponding Range States. The document has been prepared by the COP Appointed Scientific Councilors for Birds. This is a supplementary paper to COP document UNEP/CMS/COP12/Doc.25.3 on Taxonomy and Nomenclature UNEP/CMS/ScC-Sc2/Inf.3 DISAGGREGATION OF BIRD FAMILIES LISTED ON CMS APPENDIX II 1. Through Resolution 11.19, the Conference of Parties adopted as the standard reference for bird taxonomy and nomenclature for Non-Passerine species the Handbook of the Birds of the World/BirdLife International Illustrated Checklist of the Birds of the World, Volume 1: Non-Passerines, by Josep del Hoyo and Nigel J.

  • Migration Phenology of Jack Snipe Lymnocryptes Minimus at an Irish Coastal Wetland
    Migration phenology of Jack Snipe Lymnocryptes minimus at an Irish coastal wetland Tom Cooney 42 All Saint’s Road, Raheny, Dublin D05 C627 Corresponding author: [email protected] Keywords: Ireland, Jack Snipe, Lymnocryptes minimus , migration phenology Migration times of Jack Snipe Lymnocryptes minimus were monitored at North Bull Island in Dublin Bay during 2011/2012 to 2016/2017. Average arrival times in autumn centred on 2 October and average departure times in spring on 23 April. Although these results were site and habitat specific, they were similar to recent migration data for Ireland. While the time series examined for Ireland and Britain were of different lengths, migration times were extraordinarily similar. The average autumn arrival date for Ireland as a whole was 16 September while that for Britain was 23 September, and departure times in spring for Ireland centred on 30 April, one day later than in Britain. The close agreement suggests that migration times across both islands possibly occur synchronously. Other recently generated data for Ireland provides tantalising evidence that passage migration may take place and that Jack Snipe could be more frequent in upland areas than previously suspected. In both instances greater clarity will only be possible through increased observer effort and higher detection rates of this enigmatic species. Introduction Britain, but not in Ireland (Smiddy 2002).

  • Redwinged Pratincole Sometimes Mixes with Flocks of Blackwinged Pratincole, but the Nature of Such Encounters Has Not Been Documented
    454 Glareolidae: coursers and pratincoles plain system. Along the Chobe, large migrant flocks occurred in June (Randall 1994b). Reporting rates for Zimbabwe (Zone 5) were highest July–October, which may reflect movement of Okavango birds to the middle Zambezi River when the latter river’s water- levels are low. Breeding: Breeding is primarily in the late dry and early wet season: September–October in Mozambique and August–December elsewhere in southern Africa, usually when water-levels are falling or at their low- est. In Zimbabwe it may breed as late as February, but the peak is in November (Irwin 1981). Atlas data con- firm a spring/summer breeding season. Interspecific relationships: In the summer months the Redwinged Pratincole sometimes mixes with flocks of Blackwinged Pratincole, but the nature of such encounters has not been documented. The flocks are usually separated by the Redwing’s greater preference for habitats near water. Historical distribution and conservation: Although Stark & Sclater (1906) regarded the Redwinged Redwinged Pratincole Pratincole as ‘an accidental visitor’ to South Africa, this is Rooivlerksprinkaanvoël unlikely to have been the case even then.

  • The Birds of Wimbledon Common and Putney Heath 2015
    The Birds of Wimbledon Common and Putney Heath 2015 Male Wheatear on the log pile 1 The Birds of Wimbledon Common and Putney Heath 2015 The Birds of Wimbledon Common and Putney Heath 2015 espite coverage on the Common being rather poor again this year, a total of 96 species were D recorded, four more than in 2014. Of these, 45 bred or probably bred, with no doubt the highlight of the year being the successful breeding of a pair of Skylarks on the Plain, the first to do so since 2007. Much credit for this achievement must go to Wildlife & Conservation Officer, Peter Haldane, and his staff, who have persevered over the years to create a suitable and safe habitat for this Red-listed bird. Credit is also due to Chief Executive, Simon Lee, for his valuable cooperation, and indeed to the vast majority of the visiting public, many of whom have displayed a keen interest in the well-being of these iconic birds. Signage on the Plain this year was extended to the two uncut sections during the autumn and winter months, thus affording our migrants and winter-visiting birds a sanctuary in which to feed and shelter safely. Another outstanding high note this year was the Snow Bunting found on the Large Mound in January, a first for the Common since records began in 1974; and yet another first for the Common came in the form of three Whooper Swans at Rushmere in December. There was also a surprising influx of Lesser Spotted Woodpeckers during the spring, a bird that in the previous few years had become an extremely scarce visitor.

  • Cranial Pneumatization Patterns and Bursa of Fabricius in North American Shorebirds
    CRANIAL PNEUMATIZATION PATTERNS AND BURSA OF FABRICIUS IN NORTH AMERICAN SHOREBIRDS RAYIUOND MCNEIL AND JEAN BURTON study of age criteria in some species of North American shorebirds A brought us to consider two of the best known techniques of age deter- mination in birds, the size of the bursa of Fabricius and the degrees and pat- terns of skull pneumatization. The only attempt, known to us, to correlate bursa of Fabricius and gonadal development with the ossification of the skull is that of Davis (1947). The bursa of Fabricius is a lympho-epithelial organ lying dorsally above the cloaca. At least in some species it has an opening in the cloaca. It reaches its maximum size at 4-6 months and then begins involution (Davis, 1947). By cloaca1 examination of the bursal pouch, it is possible to distinguish juvenile from adult individuals of some taxa of birds especially Anseriformes and Galliformes (Gower, 1939; Hochbaum, 1942; Linduska, 1943; Kirkpatrick, 1944). Unfortunately, in shorebird species, the bursa of Fabricius has no cloaca1 opening and thus cannot be used as an age criterion of living birds. The pneumatization of the skull has been used as a criterion for estimating the age of birds by C. L. Brehm as far back as 1822 (Niethammer, 1968)) but it was not generally used until the turn of the century (Serventy et al., 1967). Miller (1946) describes the skull ossification process as follows: “The skull of a passerine bird when it leaves the nest is made of a single layer of bone in the area overlaying the brain; at least, the covering appears single when viewed mac- roscopically.

MATHUR, AND K. SIVAKUMAR Wildlife Institute of India Chandrabani, Dehradun, Uttarakhand, India K. R. ANOOP Keoladeo National Park Bharatpur, Rajasthan, India Abstract. Keoladeo National Park, a world heritage site, is famous for its rich avifaunal diversity but is now facing water shortages. Therefore, many species of migratory birds have been moving to nearby wetlands for foraging. In this connection, a survey was carried out during 2009-10 to understand the status of birds and their use of these wetlands. A total of 27 wetlands have been identified within 100 km radius of the Keoladeo National Park, and within them 75 species of water birds were recorded. Of the 27 wetlands, Rediabundh is the most species rich with 44 bird species, while only one species was found in Chicksana wetland. Larger-sized wetlands with more water attracted larger numbers of species, including more individual birds, than the smaller wetlands. A landscape level conservation plan, including these wetlands, is needed for the long term conservation of birds in Keoladeo National Park. Key words: India, Keoladeo National Park, Rediabundh, Wetland bird populations. DIVERSIDAD AVIFAUNISTICA EN LOS HUMEDALES ALEDAÑOS AL PARQUE NACIONAL KEOLADEO, BHARATPUR, RAJASTHAN, INDIA Resumen.

We suspected that birds belonging to these two areas may experience different hunting pressure or climatic conditions, and thus exhibit different demographic parameters. To test this hypothesis, we analysed spatial and temporal distribution of recoveries, and performed a ringing-recovery analysis to estimate possible survival differences between these two areas. We used methods developed by Brownie et al. in 1985. We found differences in temporal variations of the age ratio between the two ringing areas.

  • Glareola Pratincola in a Breeding Colony
    Animal Biodiversity and Conservation 40.2 (2017) 147 Activity patterns of collared pratincoles Glareola pratincola in a breeding colony I. Galván Galván, I., 2017. Activity patterns of collared pratincoles Glareola pratincola in a breeding colony. Animal Biodiversity and Conservation, 40.2: 147–152. Abstract Activity patterns of collared pratincoles Glareola pratincola in a breeding colony.— The collared pratincole Glareola pratincola is a declining wader species, but most aspects of its biology are poorly known. In this study, an attempt is made to characterize the basic behavioural repertoire of the species, searching for differences between sexes. Focal observations of the most common activities were obtained in a breeding colony in southwestern Spain. Pratincoles did not equally distribute their time among types of activity, but spent more time in alert behaviour than feeding and moving, and more time preening than moving in the colony site. Males devoted more time to vigilance for predators than females, and both sexes increased the time spent resting and decreased the time for vigilance as the breeding season progressed. These sex–related and seasonal effects on the vigilance behaviour suggest that competition for females and ambient temperature influence the daily activity pattern of collared pratincoles during breeding. Key words: Collared pratincole, Colonial breeding, Time budget, Vigilance, Waders Resumen Patrones de actividad de la canastera común Glareola pratincola en una colonia de reproducción.— La canastera común Glareola pratincola es una especie limícola en retroceso; no obstante, se conoce poco sobre la mayor parte de los aspectos relativos a su biología.

In the afternoon we flew south towards the city of Raipur. In the morning we visited the Humayan’s Tomb and the Quitab Minar in Delhi; both of these UNESCO World Heritage Sites were outstanding, and we all enjoyed them immensely. Also, we picked up our first birds, a pair of Alexandrine Parakeets, a gorgeous White-throated Kingfisher, and lots of taxonomically interesting Black Kites, plus a few Yellow-footed Green Pigeons, with a Brown- headed Barbet showing wonderfully as well. Rufous Treepie by Machiel Valkenburg From Raipur we drove about four hours to our fantastic lodge, “the Baagh,” located close to the entrance of Kanha National Park. The park is just plain awesome when it comes to the density of available tigers and birds. It has a typical central Indian landscape of open plains and old Sal forests dotted with freshwater lakes. In the early mornings when the dew would hang over the plains and hinder our vision, we heard the typical sounds of Kanha, with an Indian Peafowl displaying closely, and in the far distance the song of Common Hawk-Cuckoo and Southern Coucal.
