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.

Effects of Experimental Noise Exposure on Songbird Nesting Behaviors and Nest Success
EFFECTS OF EXPERIMENTAL NOISE EXPOSURE ON SONGBIRD NESTING BEHAVIORS AND NEST SUCCESS A Thesis presented to the Faculty of California Polytechnic State University, San Luis Obispo In Partial Fulfillment of the Requirements for the Degree Masters of Science in Biological Sciences by Tracy Irene Mulholland August 2016 © 2016 Tracy Irene Mulholland ALL RIGHTS RESERVED ii COMMITTEE MEMBERSHIP TITLE: Effects of Experimental Noise Exposure on Songbird Nesting Behaviors and Nest Success AUTHOR: Tracy Irene Mulholland DATE SUBMITTED: August 2016 COMMITTEE CHAIR: Clinton D. Francis, Ph.D. Assistant Professor of Biological Sciences COMMITTEE MEMBER: Emily Taylor, Ph.D. Associate Professor of Biological Sciences COMMITTEE MEMBER: Sean Lema, Ph.D. Associate Professor of Biological Sciences iii ABSTRACT Effects of Experimental Noise Exposure on Songbird Nesting Behaviors and Nest Success Tracy Irene Mulholland Anthropogenic noise is an increasingly prevalent global disturbance. Animals that rely on the acoustical environment, such as songbirds, are especially vulnerable to these sounds. Traffic noise, in particular, overlaps with the frequency range of songbirds, creating masking effects. We investigated the effects of chronic traffic noise on provisioning behaviors and breeding success of nesting western bluebirds (Sialia mexicana) and ash-throated flycatchers (Myiarchus cinerascens). Because anthropogenic noise exposure has the potential to interrupt parent-offspring communication and alter vigilance behaviors, we predicted that traffic noise would lead to changes in provisioning behaviors, such as fewer visits to the nest box, for each species. We also predicted the noise to negatively influence one or more metrics reflective of reproductive success, such as nest success, clutch size, number of nestlings or number of fledglings. -

An important metric for many aspects of species conservation planning and risk assessment is an estimate of total population size. For landbirds breeding in North America, Partners in Flight (PIF) generates global, continental, and regional population size estimates. These estimates are an important component of the PIF species assessment process, but have also been used by others for a range of applications. The PIF population size estimates are primarily calculated using a formula designed to extrapolate bird counts recorded by the North American Breeding Bird Survey (BBS) to regional population estimates. The extrapolation formula includes multiple assumptions and sources of uncertainty, but there were previously no attempts to quantify this uncertainty in the published population size estimates aside from a categorical data quality score. Using a Monte Carlo approach, we propagated the main sources of uncertainty arising from individual components of the model through to the final estimation of landbird population sizes. -

Importance of Sycamores to Riparian Birds in Southeastern Arizona
j. Field Ornithol., 55(1):97-103 IMPORTANCE OF SYCAMORES TO RIPARIAN BIRDS IN SOUTHEASTERN ARIZONA BY CARL E. BOCKAND JANE H. BOCK Southwesternriparian woodlands are major centersof aviandiversity and abundance(Carothers et al. 1974, Stevenset al. 1977, Wauer 1977, Stamp1978, Szaro 1981). Cottonwood(Populusfremontii) communities in lowlandriver valleyshave been well-studied,and the importanceof theselarge trees to riparian birds is striking (Carotherset al. 1974, Andersonand Ohmart 1977, Ohmart et al. 1977). Riparian woodlands at higher elevationsin the Southwestinclude a greater variety of de- ciduoustrees (Paseand Layser 1977), but their bird populationshave not been as thoroughlyexamined (Szaro 1980). Intermittent and perennial streamsassociated with oak (Quercus) woodlandsof southeasternArizona supportriparian communitiesdom- inated by Arizona sycamore(Platanus wrightii), Arizona ash (Fraxinus velutina),and Arizona blackwalnut (Juglans major; Lowe 1964). Because thesestreams are lined with nearly continuousstands of oak, it is not clear that large riparian trees would be as important to birds here as they are in lowlanddesert situations. Among the mid-elevationriparian trees, sycamoresare of potential value to birds becauseof their large size and substantialdead wood. They alsoappear to be one of the mostthreatened tree species.Sexual reproductionseems limited or lackingin sycamorepopulations through- out the region (Glinsky1977, pers.ohs.). Livestock grazing, drying of formerlyperennial streams, and/or flashflooding all appearto play a role in causingthis reproductivefailure. The Appleton-Whittell Re- searchRanch is a 3160 ha sanctuaryof the National AudubonSociety, at about 1500 m elevationin SantaCruz County,southeastern Arizona. The site hasbeen protectedfrom livestockand other disturbancesince 1968. Seedlingsand saplingsof ashand walnut were commonin 1982- 83 along intermittent rocky streamson the sanctuary,but there were only three sycamoresaplings and no seedlingson the entire property. -
