Geographic Variation and Species Limits in Middle American Woodnymphs (Thalurania)
THEWILSONBULLETIN A QUARTERLY MAGAZINE OF ORNITHOLOGY Published by the Wilson Ornithological Society VOL. 104, No. 2 JUNE 1992 PAGES 205-388 Wilson Bull., 104(2), 1992, pp. 205-219 GEOGRAPHIC VARIATION AND SPECIES LIMITS IN MIDDLE AMERICAN WOODNYMPHS (THALURANIA) PATRICIA ESCALANTE-PLIEGO ’ AND A. TOWNSEND PETERSON* ABSTRACT.- We analyzed geographic variation in morphology and plumage coloration in male woodnymphs of the genus Thalurunia in Middle America and northwestern South America. Morphometric characters distinguish the disjunct western Mexican populations from populations to the south. Three groups are distinguished by discrete plumage coloration characters. We propose that these groups be recognized as separate species: T. ridgwuyiof western Mexico; T. colombicaof Central America south to western Panama and disjunctly in interior northwestern South America; and T.fannyi ofeastem Panama, western Colombia, and northern Ecuador. Received1 I July 1991, accepted20 Sept. 1991. RESUMEN.-En este trabajo analizamos la variation geografica en morfologia yen patrones de coloration en el plumaje de 10s machos de las “ninfas de bosque” de1 genera Thalurunia de Mesoamerica y noroeste de Sudamtrica. Los caracteres morfometricos distinguen las poblaciones de1 oeste de Mexico de todas las poblaciones de1 sur. Con base en la coloration de1 plumaje, caracteres discretos separan tres grupos. Proponemos que estos grupos Sean reconocidos coma especies distintas: T. ridgwayi de1 oeste de MCxico; T. colombicadesde Centroamerica hacia el sur al oeste de Panama y continuando desputs en el noroeste de Sudamerica; y T.fannyi de1 este de Panama, oeste de Colombia y extremo norte de1 Ecuador. In spite of more than a century of study, patterns of geographic variation and speciation in Middle American birds remain poorly understood. -

UP IN THE AIR: INFORMING AND IMAGINING CLIMATE ADAPTATION ALONG THE NEW JERSEY SHORE By DAVID C. EISENHAUER A dissertation submitted to the School of Graduate Studies Rutgers, The State University of New Jersey In partial fulfillment of the requirements For the degree of Doctor of Philosophy Graduate Program in Geography Written under the direction of Robin Leichenko And approved by _____________________________________ _____________________________________ _____________________________________ _____________________________________ New Brunswick, New Jersey October 2019 ii © 2019 David C. Eisenhauer ALL RIGHTS RESERVED ii ii ABSTRACT OF THE DISSERTATION Up in the Air: Informing and Imagining Climate Adaptation along the New Jersey Shore by DAVID C. EISENHAUER Dissertation Director: Robin Leichenko In this dissertation, I examine the challenges posed by climate change to the New Jersey shore region as well as efforts to inform and support successful adaptation policies. The core argument of the dissertation is the region needs transformational change in the near term if a socially and ecologically vibrant future is to be achieved. Informing the design and supporting the implementation of sustainable transformational pathways requires engaging with the deeply entrenched cultural, economic, and political commitments that configure contemporary development within the New Jersey shore region. By drawing upon archival and historical research along with semi-structured interviews and participant observation, I demonstrate that historical and contemporary processes have contributed to material and imaginative path dependencies within the shore region that have led to governance and management prioritizing private property rights and economic growth over ecological and social sustainability. I argue that to support more just and sustainable pathways, practitioners working within the boundaries of science and policy must engage more with the political, imaginative, and normative dimensions of collective life in the New Jersey shore region. -
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.

DOI: http://dx.doi.org/10.15446/abc. v25n1.77442 ABSTRACT Several scientific reasons support continuing bird collection in Colombia, a megadiverse country with modest science financing. Despite the recognized value of biological collections for the rigorous study of biodiversity, there is scarce information on the monetary costs of specimens. We present results for three expeditions conducted in Santander (municipalities of Cimitarra, El Carmen de Chucurí, and Santa Barbara), Colombia, during 2018 to collect bird voucher specimens, quantifying the costs of obtaining such material. After a sampling effort of 1290 mist net hours and occasional collection using an airgun, we collected 300 bird voucher specimens, representing 117 species from 30 families. -

Yet, it was still too early to experience the real explosion of bird song, which usually happens after dawn. Then, after 05:30 AM, the chorus started when a vocal Great Kiskadee broke the morning silence, followed by the scratchy notes of two Hoffmann´s Woodpeckers, a nesting pair of Inca Doves, the ascending and monotonous song of the Yellow-bellied Elaenia, and the cacophony of an (apparently!) engaged pair of Rufous-naped Wrens. This was indeed a warm welcome to magical Costa Rica! To complement the first morning of birding, two boreal migrants, Baltimore Orioles and a Tennessee Warbler, joined the bird feast just outside the hotel area. Broad-billed Motmot . Photo: D. Ascanio © Victor Emanuel Nature Tours 2 The Best of Costa Rica, 2019 After breakfast, we drove towards the volcanic ring of Costa Rica. Circling the slope of Poas volcano, we eventually reached the inspiring Bosque de Paz. With its hummingbird feeders and trails transecting a beautiful moss-covered forest, this lodge offered us the opportunity to see one of Costa Rica´s most difficult-to-see Grallaridae, the Scaled Antpitta. -

Tropical Birding Trip Report Costa Rica: The Introtour | July 2017 A Tropical Birding SET DEPARTURE tour Costa Rica: The Introtour July 15 – 25, 2017 Tour Leader: Scott Olmstead INTRODUCTION This year’s July departure of the Costa Rica Introtour had great luck with many of the most spectacular, emblematic birds of Central America like Resplendent Quetzal (photo right), Three-wattled Bellbird, Great Green and Scarlet Macaws, and Keel-billed Toucan, as well as some excellent rarities like Black Hawk- Eagle, Ochraceous Pewee and Azure-hooded Jay. We enjoyed great weather for birding, with almost no morning rain throughout the trip, and just a few delightful afternoon and evening showers. Comfortable accommodations, iconic landscapes, abundant, delicious meals, and our charismatic driver Luís enhanced our time in the field. Our group, made up of a mix of first- timers to the tropics and more seasoned tropical birders, got along wonderfully, with some spying their first-ever toucans, motmots, puffbirds, etc. on this trip, and others ticking off regional endemics and hard-to-get species. We were fortunate to have several high-quality mammal sightings, including three monkey species, Derby’s Wooly Opossum, Northern Tamandua, and Tayra. Then there were many www.tropicalbirding.com +1-409-515-9110 [email protected] Page Tropical Birding Trip Report Costa Rica: The Introtour | July 2017 superb reptiles and amphibians, among them Emerald Basilisk, Helmeted Iguana, Green-and- black and Strawberry Poison Frogs, and Red-eyed Leaf Frog.

Diet and Foraging Ecology of African Harrier Hawk (Polyboroides Typus) in Ehor Forest Reserve, Edo State, Nigeria
Journal of Researches in Agricultural Sciences Vol. 5 (2), 2017 Diet and Foraging Ecology of African Harrier Hawk (Polyboroides typus) in Ehor Forest Reserve, Edo State, Nigeria 1E.F. Okosodo, 2J.O. Orimaye, 1O. Aladelusi and 3O.O. Kolawole 1Department of Ecotourism and Wildlife Management, The Federal University of Technology, Akure, Ondo State 2Department of Forest Resources and Wildlife Management, Ekiti State University Ado-Ekiti, Ekiti State 3Department of Hospitality and Tourism, Federal Polytechnic, Ilaro Ogun State Email: [email protected] Abstract Feeding is an indispensable activity in the life of birds. It is crucial for their survival but the demands of food acquisition impose significant challenges to both the physiology and behavior of birds. Thus, this study on the feeding ecology of African harrier hawk is imperative for understanding the species adaptation to environments and also a crucial factor to be considered while examining their economic status. This research study investigated the diet and foraging ecology of the African harrier-hawk (Polyboroides typus) in Ehor Forest Reserve, Edo State, Nigeria. Direct field observation method was used to collect data for 12 months on the diet and foraging ecology of the bird species. The study area was divided into three compartments according to land use types, (mature forest, logged area, and farmlands). The results show that the African harrier-hawk consumed a variety of small animals, insects and fruits of some plant species. The frogs, lizards, adults, eggs of bird species and insects constituted 87.25% of the diets while plant resources made up 12.75%. The major diet resources were bird species belonging to the family Ploceidae and frogs; and the fruits of oil palm (Elaeis guineensis) and African pear (Dacryodes edulis). -

Monday 13 March 2017—6.30 pm—Julian Hume—In search of the dwarf emu: extinct emus of Australian islands. Abstract: King Island and Kangaroo Island were once home to endemic species of dwarf emu that became extinct in the early 19th century. Emu egg shells have also been found on Flinders Island, which suggests that another emu species may have formerly occurred there. In 1906 J. A. Kershaw undertook a survey of King Island searching for fossil specimens and found emu bones in sand dunes in the south of the island.
