A. Berle ticed that someof our longest-term,most experiencededitors have retired. To each of them we extend our warmest thanks for their years of devoted President and Publisher service,their excellentjob of chroniclingbird life seasonafter season,and their J. R Myers thoughtfulinsights into the avian dynamicsof their regions. Senior Vice President for Science and Sanctuaries When Daniel D. Gibson was a university student in 1967, he became the first American Birds Regional Editor for the Alaska Region. At that time Susan Roney Drennan Editor-m-Chief preciouslittle wasknown about the statusand distributionof many of Alaska's geographicallyrestricted species. Back in the late 1960s,Birds of Alaska, by Vice President for Gabrielsonand Lincoln (1959), wasthe referenceof authority. Gabrielsonand Science Information Lincoln discussed312 speciesof birds known from the state. Now, upward of Donna M. Pisacano 430 speciesare known to have occurred in Alaska. Many of those additions Managing Editor were documentedin American Birds by our correspondents.Gibson worked Kenn Kaufman diligently to transform raw data into readable, cogent reports. He built a Associate Editor network of careful observers. He stirred our imaginations and opened a window on a little-known world. Under Dan's editorship over these past 22 Geoff LeBaron years,readers have learned about the exciting endemicsin Beringia, as well as Christmas Bird Count Editor the stray migrant or casual "Asiatics", most of which can only be seen in this Irene Connelly country in Alaska. Gibson has unfailingly provided our readerswith views of Administrative Assistant the spectacularbirdlife of this 5800 squaremile region. His reporting ability has been astounding.His column has been a delicately balanced enterprise Phyllis Lutyens betweenultra-rarities and trends.His sterlingreports have been sheerpleasures Assistant to the Editor to read. We feel incomparablyfortunate and gratefulto have had him on our Tyrone A. Horton sidefor so long. Thanks so much, Dan. Circulation/BusinessManager Janet Witzeman joined the ranks of the Regional Editors in 1975. As one Chandler S. Robbins of the few women editors she brought a new level of cohesionand unity to Technical Editor the SouthwestRegion. Her reportstook on a new intensity and her standards AIdeen and Willet T. Van Velzen were exceedinglyhigh. She had a specialappreciation for the discoveriesof Co-editors her observersand placed the acceptanceof new recordson a more scientific Breeding Bird Censuses level. Janet continuesin that role as the current Secretaryfor the Arizona Bird RecordsCommittee. We have alwaysadmired her ability to weavetogether a Calvin L. Cink and Roger L.

We have all benefitedfrom the accuracyand precisionof her columns,and her particular viewpointregarding Arizona bird life. Thanks, ADVISORS Janet, your contributionto American Birds has been incalculable. Carl E. Bock Phillip W. Mattocks, Jr., 12-year veteran Regional Editor for the Northern Mary H. Clench Pacific Coast Region, has retired. The Region has an incomparablewealth of John Farrand, Jr. Frank B. Gill marine life whose birds function in its health. Inland there is a profusion of Thomas R. Howell birdlife, on which Phil conscientiouslyreported. The subtledifferences between Frances C.

    Studies in Avian Biology No. 19:272-280, 1999. SEASONAL MOVEMENTS AND CONSERVATION OF SEEDEATERS OF THE GENUS SPOROPHZIA IN SOUTH AMERICA Jose MARIA CARDOSO DA SILVA Abstract. Small seed-eating finches of the genus Sporophila, commonly called seedeaters, are among the most characteristic elements of South Americas’ grassland avifauna. Twenty-three species of Spa- rophila seedeaters were classified into three groups according to their seasonal movements. Fourteen species make long-distance movements between at least two major ecological regions in South Amer- ica, four species make intermediate to long-distance movements within a single ecological region, and five species make short-distance movements between adjacent habitats. The grasslands in the Cerrado region seem to be the most important wintering sites for most of the long-distance migrant Sporophila. Mapping the ranges of all threatened or near-threatened Sporophila species identified seven critical areas between southern coastal Colombia and southernmost Brazil. Creating reserves in these seven areas would protect at least one population of 23 Sporophilu species. Mapping the ranges of all species and well-marked subspecies with restricted ranges (350,000 square kilometers or less) identified nine critical areas (five of which were also identified by mapping threatened or near-threatened species) between northern South America and southernmost Brazil. Creating reserves in these nine areas would protect populations of 29 species or well-defined subspecies of Sporophila.The conservation of South American grasslands needs urgent action. The areas identified here are important grassland habitats that should be priority areas for organizations and agencies interested in grassland conservation.

Montaldo Received: 23 July 2010 / Accepted: 15 July 2011 / Published online: 24 July 2011 Ó Springer Science+Business Media B.V. 2011 Abstract In this paper we summarize for the first time the effects of agriculture expansion and intensification on animal diversity in the Pampas of Argentina and discuss research needs for biodiversity conservation in the area. The Pampas experienced little human intervention until the last decades of the 19th century. Agriculture expanded quickly during the 20th century, transforming grasslands into cropland and pasture lands and converting the landscape into a mosaic of natural fragments, agricultural fields, and linear habitats. In the 1980s, agriculture intensification and replacement of cattle grazing- cropping systems by continuous cropping promoted a renewed homogenisation of the most productive areas. Birds and carnivores were more strongly affected than rodents and insects, but responses varied within groups: (a) the geographic ranges and/or abundances of many native species were reduced, including those of carnivores, herbivores, and specialist species (grassland-adapted birds and rodents, and probably specialized pollinators), sometimes leading to regional extinction (birds and large carnivores), (b) other native species were unaffected (birds) or benefited (bird, rodent and possibly generalist pollinator and crop-associated insect species), (c) novel species were introduced, thus increasing species richness of most groups (26% of non-rodent mammals, 11.1% of rodents, 6.2% of birds, 0.8% of pollinators).

    Diversity and Natural History of Birds in Green Urban Areas of the City of Quito, Ecuador (America)

    Diversity and natural history of birds in green urban areas of the city of Quito, Ecuador (America) Diego F. Cisneros-Heredia1,2,3* & Eliana Montenegro1 1 Universidad San Francisco de Quito, Colegio de Ciencias Biológicas y Ambientales, Laboratorio de Zoología Terrestre. Casilla Postal 17-1200-841, Quito, Ecuador 2 King’s College London, Department of Geography, Strand, London WC2R 2LS, UK 3 Aves&Conservación / BirdLife Ecuador, Quito, Ecuador * E-mail: [email protected] Abstract The diversity and ecology of urban bird communities have been extensively studied in Neartic and Paleartic areas, however, little is known about urban Neotropical areas. Quito, capital city of Ecuador, is located on a highland valley in the megadiverse tropical Andes. Founded in 1534, Quito did not increase significantly its urban area until the late 19th century, growing at an accelerated and unplanned rate during the 20th century. More than 100 species were known to inhabit in Quito at the end of the 19th century. Currently, most authors estimated that no more than 40 species occur in Quito, although no systematic bird studies have been conducted. Our research is a first approach to the avifauna of Quito, surveying the diversity living in green urban areas within the city borders. We used two field methodologies, i.e. line transects and point counts, to survey 16 green urban areas over 12 months. We recorded 65 species of birds, belonging to 20 families and 9 orders. Three species were the most common and frequent: Eared Dove Zenaida auriculata, Rufous-collared Sparrow Zonotrichia capensis, and Great Thrush Turdus fuscater, being omnivores and granivores adapted to anthropic habitats with low ecological complexity.

    The Natural Choice for Wildlife Holidays Welcome

    HOLIDAYS WITH 100% FINANCIAL PROTECTION The natural choice for wildlife holidays Welcome After spending considerable time and effort reflecting, questioning what we do and how we do it, and scrutinising the processes within our office and the systems we use for support, I am delighted to say that we are imbued with a new vigour, undiminished enthusiasm, and greater optimism than ever. My own determination to continue building on the solid foundation of twenty years of experience in wildlife tourism, since we started from very humble beginnings – to offer what is simply the finest selection of high quality, good value, tailor-made wildlife holidays – remains undaunted, and is very much at the core of all we do. A physical move to high-tech office premises in the attractive city of Winchester leaves us much better connected to, and more closely integrated with, the outside world, and thus better able to receive visitors. Our team is leaner, tighter, more widely travelled and more knowledgeable than ever before, allowing us to focus on terrestrial, marine and – along with Dive Worldwide – submarine life without distraction. In planning this brochure we deliberately set out to whet the appetite, and make no mention of either dates or prices. As the vast majority of trips are tailored to our clients’ exact requirements – whether in terms of itinerary, duration, standard of accommodation or price – the itineraries herein serve merely as indications of what is possible. Thereafter, you can refine these suggestions in discussion with one of our experienced consultants to pin down your precise needs and wants, so we can together create the wildlife holiday of your dreams.

    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.

    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.
