Sep2013 Newsletter.Pub September 2013 Galloping Through The Galapagos John Cleal and Marion Homier will present “Wildlife Photographs from the Galapagos Islands” at the September 16, 2013 meeting of the Oklahoma City Audubon Society. Marion and John took a month to visit the Galapagos Islands and Amazon Basin in 2007. They photographed the wildlife they encountered. They are amateur photographers only and do not have expensive equipment. However wildlife, particularly in the Galapagos, is usually quite tame so some interesting pictures resulted regardless. Marion and John share an interest in all aspects of the natural world. Marion is a Federal retiree and has adapted well to retirement over the past two years. In addition to travel, wildlife watching and photography with John, thanks to him she has also discovered a latent addiction to golf. She is continually distracted by bird calls and flyovers during her backswing and her preferred courses are those that are “birdiest.” Their golf equipment includes birding binoculars! John is also retired, being allergic to work in any form. Besides nature watching, he is dedicated to the pursuit of sloth and lethargy, and losing at golf, chess and the battle with weeds. Please join us on Monday, September 16 for an enjoyable evening of bird photos and birders! Our meetings are held September through June on the third Monday of each month. They begin at 7:00 p.m. at the Will Rogers Garden Center, I-44 and NW 36th Street. Visitors are always welcome.

Black-capped Donacobius, President’s Perspective http://www.xeno-canto.org/131419 By Bill Diffin Red-whiskered Bulbul, http://www.xeno-canto.org/97419 In the April, May and June articles we Grey-cheeked Bulbul, http://www.xeno-canto.org/35825 listened to songs of sylvioid birds from Cetti's Warbler, http://www.xeno-canto.org/142083 both the Old World and the New. Below Chestnut-headed Tesia, is a sampling of calls from these same http://www.xeno-canto.org/114886 species. Sibley's guide often describes Yellow-throated Woodland Warbler, two or three calls for a species with http://www.xeno-canto.org/28817 names indicating their functions like Common Chiffchaff, http://www.xeno-canto.org/146689 alarm call, flight call, chase call, contact Singing Cisticola, http://www.xeno-canto.org/99668 call, etc. At least some species have Whistling Cisticola -1, http://www.xeno-canto.org/127081 many calls. For example the great Whistling Cisticola -2, http://www.xeno-canto.org/127082 variety of chickadee calls was Whistling Cisticola -3, http://www.xeno-canto.org/127080 demonstrated in one of the sources linked in the April Trilling Cisticola, http://www.xeno-canto.org/48433 article. Rattling Cisticola, http://www.xeno-canto.org/116030 Chestnut-throated Apalis, Because bird songs are louder, more extended and more http://www.xeno-canto.org/71443 complex than calls, they often seem more important to us. Eurasian Blackcap, http://www.xeno-canto.org/144602 In fact though calls must be just as important as songs to Striated Laughingthrush -1, the lives of birds. Mated pairs undoubtedly communicate http://www.xeno-canto.org/115742 about predators, territorial threats from rival pairs, the Striated Laughingthrush -2, brooding female's need for food, who will mind the http://www.xeno-canto.org/115743 youngsters at any given time, etc. We really don't know how Striated Laughingthrush -3, detailed the communication is between pairs. Scientific http://www.xeno-canto.org/115745 investigation in this area doesn't seem to have progressed very far. However consider that the song of a male in breeding condition may be more than just evidence of his health and strength. It may be testimony to his fitness as a communicator, his Oklahoma City Audubon vocabulary, his range of expression from urgent panic to bold agression. Among the collection of calls below, certain Society themes stand out as particularly frequent. One is a jay-like "jeer" or "jay". Another is a sharp "chip" or "chup" which Officers 2013 may be repeated frequently enough to be considered a chatter. See if you recognize in the non-U.S. birds President Bill Diffin 722-3778 some calls very similar to the ones you hear locally.

  • 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.

  • Egg-Spot Matching in Common Cuckoo Parasitism of the Oriental Reed
    Li et al. Avian Res (2016) 7:21 DOI 10.1186/s40657-016-0057-y Avian Research RESEARCH Open Access Egg‑spot matching in common cuckoo parasitism of the oriental reed warbler: effects of host nest availability and egg rejection Donglai Li1†, Yanan Ruan1†, Ying Wang1, Alan K. Chang1, Dongmei Wan1* and Zhengwang Zhang2 Abstract Background: The success of cuckoo parasitism is thought to depend largely on the extent of egg matching between cuckoo and host eggs, since poor-matching cuckoo egg would lead to more frequent egg rejection by the host. In this study, we investigated how egg-spot matching between the Common Cuckoo (Cuculus canorus) and its host, the Oriental Reed Warbler (Acrocephalus orientalis) is affected by the local parasitism rate, nest availability in breeding synchronization and egg rejection. Methods: We used the paired design of parasitized and their nearest non-parasitized nests where breeding occurred simultaneously to compare egg-spot matching. The image analysis was used to compare four eggshell pattern vari- ables, namely spot size, density, coverage on the different areas of egg surface, and the distribution on the whole egg surface. Egg recognition experiments were conducted to test the effect of egg spots on egg rejection by the host. Results: Our results show that much better matching in almost all spot parameters tested on the side of the egg and the spot distribution on the whole egg occurred in parasitized nests than in non-parasitized nests. Matching of spot density between cuckoo and host eggs in parasitized nests increased with the synchronization between temporal availability of nests and the egg-laying period of female cuckoos.

    Adaptations of An Avian Supertramp: Distribution, Ecology, and Life History of the Pearly-Eyed Thrasher (Margarops fuscatus) Chapter 6: Survival and Dispersal The pearly-eyed thrasher has a wide geographical distribution, obtains regional and local abundance, and undergoes morphological plasticity on islands, especially at different elevations. It readily adapts to diverse habitats in noncompetitive situations. Its status as an avian supertramp becomes even more evident when one considers its proficiency in dispersing to and colonizing small, often sparsely The pearly-eye is a inhabited islands and disturbed habitats. long-lived species, Although rare in nature, an additional attribute of a supertramp would be a even for a tropical protracted lifetime once colonists become established. The pearly-eye possesses passerine. such an attribute. It is a long-lived species, even for a tropical passerine. This chapter treats adult thrasher survival, longevity, short- and long-range natal dispersal of the young, including the intrinsic and extrinsic characteristics of natal dispersers, and a comparison of the field techniques used in monitoring the spatiotemporal aspects of dispersal, e.g., observations, biotelemetry, and banding. Rounding out the chapter are some of the inherent and ecological factors influencing immature thrashers’ survival and dispersal, e.g., preferred habitat, diet, season, ectoparasites, and the effects of two major hurricanes, which resulted in food shortages following both disturbances. Annual Survival Rates (Rain-Forest Population) In the early 1990s, the tenet that tropical birds survive much longer than their north temperate counterparts, many of which are migratory, came into question (Karr et al. 1990). Whether or not the dogma can survive, however, awaits further empirical evidence from additional studies.

  • The Ornithological Importance of Thrumshingla National Park, Bhutan
    FORKTAIL 16 (2000): 147-162 The ornithological importance of Thrumshingla National Park, Bhutan CAROL INSKIPP, TIM INSKIPP and SHERUB Thrumshingla National Park is one of four national parks in Bhutan and was gazetted in 1998 to ensure the conservation of biodiversity in the central belt of the country. Two bird surveys have been carried out in the park: in April and May 1998 and in January 2000. Based on these surveys and records from other sources, a list of 345 bird species has been compiled for the park up to the end of May 2000. This includes three globally threatened species, 15 of Bhutan’s near-threatened species and eight of the country’s 11 restricted range species. Warm broadleaved forest was found to be the most valuable for bird species in both the breeding season and in winter, followed by cool broadleaved forest. Fir and hemlock, especially those with an understorey of rhododendron and bamboo, were the richest forests for birds at higher altitudes. INTRODUCTION highway runs through approximately the middle of the park from Bumthang, via Ura, Sengor, Namling, Bhutan lies in the eastern Himalayas, one of the world’s Yongkhala to Lingmethang.
