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.

However, confirmation is scarce in natural populations. Here we studied the major haemoglobin genes of eight Andean duck lineages and compared them to 115 other waterfowl species, including the bar-headed goose (Anser indicus) and Abyssinian blue-winged goose (Cyanochen cyanopterus), two additional species living at high altitude. One to five amino acid replacements were significantly overrepresented or derived in each highland population, and parallel substitutions were more common than in simulated sequences evolved under a neutral model. Two substitutions evolved in parallel in the aA subunit of two (Ala-a8) and five (Thr-a77) taxa, and five identical bA subunit substitutions were observed in two (Ser-b4, Glu-b94, Met-b133) or three (Ser-b13, Ser-b116) taxa. -
Peru: from the Cusco Andes to the Manu
The critically endangered Royal Cinclodes - our bird-of-the-trip (all photos taken on this tour by Pete Morris) PERU: FROM THE CUSCO ANDES TO THE MANU 26 JULY – 12 AUGUST 2017 LEADERS: PETE MORRIS and GUNNAR ENGBLOM This brand new itinerary really was a tour of two halves! For the frst half of the tour we really were up on the roof of the world, exploring the Andes that surround Cusco up to altitudes in excess of 4000m. Cold clear air and fantastic snow-clad peaks were the order of the day here as we went about our task of seeking out a number of scarce, localized and seldom-seen endemics. For the second half of the tour we plunged down off of the mountains and took the long snaking Manu Road, right down to the Amazon basin. Here we traded the mountainous peaks for vistas of forest that stretched as far as the eye could see in one of the planet’s most diverse regions. Here, the temperatures rose in line with our ever growing list of sightings! In all, we amassed a grand total of 537 species of birds, including 36 which provided audio encounters only! As we all know though, it’s not necessarily the shear number of species that counts, but more the quality, and we found many high quality species. New species for the Birdquest life list included Apurimac Spinetail, Vilcabamba Thistletail, Am- pay (still to be described) and Vilcabamba Tapaculos and Apurimac Brushfnch, whilst other montane goodies included the stunning Bearded Mountaineer, White-tufted Sunbeam the critically endangered Royal Cinclodes, 1 BirdQuest Tour Report: Peru: From the Cusco Andes to The Manu 2017 www.birdquest-tours.com These wonderful Blue-headed Macaws were a brilliant highlight near to Atalaya. -
Notes on Some Argentine Anatids
NOTESON SOME ARGENTINEANATIDS' MILTON W. WELLER ROM mid-August, 1964, until late July, 1965, I was engaged in field work F in Argentina studying waterfowl. Although special emphasis was placed on the Black-headed Duck (Heteronetta atricapilla) , 28 species of anatids were observed in various parts of Argentina. Because so little is known of these species, some general observations are summarized and discussed in the hope that it will point out gaps in our knowledge and encourage additional work on this interesting group. Field work was financed by Grant GB-1067 from the National Science Foundation. Studies of museum specimens in the United States were financed by a Chapman Grant of the American Museum of Natural History, and aided materially in appraising the significance of plumage sequences in Neotropical ducks. AQUATIC HABITATS Although the distribution of Argentine birds was considered by Dabbene (1910) and by Olrog (19591, little comment has been made on the distribution of water types and their influence on waterfowl distribution. Some helpful botanical comments are given by Cabrera (1953) for the Buenos Aires region and, Wetmores’ (1926) observations on both botany and ornithology are excellent. Although time did not permit detailed botanical work during this study, some obvious differences in life-form of marsh vegetation were recorded in the areas visited (Fig. 1) in relation to the species composi- tion of waterbirds. The most extensive zone of freshwater and semipermanent marshes is found in an area roughly bordered by the cities of Venado Tuerto (Santa Fe), Buenos Aires, General Lavalle, Mar de1 Plats and Azul (Buenos Aires). -

21 Sep 2018 Lists of Victims and Hosts of the Parasitic
version: 21 Sep 2018 Lists of victims and hosts of the parasitic cowbirds (Molothrus). Peter E. Lowther, Field Museum Brood parasitism is an awkward term to describe an interaction between two species in which, as in predator-prey relationships, one species gains at the expense of the other. Brood parasites "prey" upon parental care. Victimized species usually have reduced breeding success, partly because of the additional cost of caring for alien eggs and young, and partly because of the behavior of brood parasites (both adults and young) which may directly and adversely affect the survival of the victim's own eggs or young. About 1% of all bird species, among 7 families, are brood parasites. The 5 species of brood parasitic “cowbirds” are currently all treated as members of the genus Molothrus. Host selection is an active process. Not all species co-occurring with brood parasites are equally likely to be selected nor are they of equal quality as hosts. Rather, to varying degrees, brood parasites are specialized for certain categories of hosts. Brood parasites may rely on a single host species to rear their young or may distribute their eggs among many species, seemingly without regard to any characteristics of potential hosts. Lists of species are not the best means to describe interactions between a brood parasitic species and its hosts. Such lists do not necessarily reflect the taxonomy used by the brood parasites themselves nor do they accurately reflect the complex interactions within bird communities (see Ortega 1998: 183-184). Host lists do, however, offer some insight into the process of host selection and do emphasize the wide variety of features than can impact on host selection. -

Placement Student's Final Report*
Placement Student’s Final Report* LAURA CANNON *Abridged from original. Contains only Scientific Report portion. SCIENTIFIC REPORT THE EFFECT OF AN ARTIFICAL FEEDER ON HUMMINGBIRD BEHAVIOUR ABSTRACT Like their fellow nectavores, Hummingbirds try to maximize the ratio of energy obtained to energy expended; they try to consume as much nectar with as little movement as they can (Feinsinger, 1978; Hainsworth & Wolf, 1972). The way in which they optimize their consumption is through their ecologically defined roles, they behave in such a way to increase their chances of obtaining food; they often match the length of their bill to the length of the flower. Montgomerie & Gass (1981) noted that Hummingbirds abundance appears to be limited by the availability of nectar. In this study the presence of the artificial feeder provides a constant supply of food while it is up, which could cause a change in the Hummingbirds behaviour for example are maurders (bare in and feed) seen to convert to trapliners (visit multiple flowers), or territorialists (defenders) to become filchers (thieves)? Artificial feeders can affect hummingbirds foraging behaviour and abundance, but despite its potential importance, few previous studies have focused on the consequences of nectar feeders giving contradictory results (Feinsinger, 1978; Sonne et al., 2015). In a study by Arizmendi et al., (2007) the presence of a nectar feeder reduced hummingbird visitation to nearby plants in their study in Mexico. However in Brockmeyer and Schaefer’s study (2012) the number of visits to the flowers around the feeder increased when the feeder was present. This studies main focus is to determine how the presence of an artificial feeder affects the hummingbird’s behaviour specifically feeding, perching and aggression.
