Mt. Tabor Park Breeding Bird Survey Results 2009
The Mount Tabor Invasive Plant Control and Revegetation Project and its affects on birds INTRODUCTION In order to reestablish a healthier native forest environment and improve the health of the watershed, a multi-year project is underway at Mt. Tabor Park to remove invasive plants. Actual removal of non-native species, the planting of native species, and other tasks began in September 2010. So as to monitor how these changes would affect the native bird species on Mt. Tabor, breeding bird and area search surveys were begun in 2009. BES created the protocol for the point counts. Herrera Environmental Consultants, Inc. set up 24 avian point count stations and conducted the initial year of surveys. Station 10 was later deemed unsuitable and data was not collected at this location. During years two and three Audubon Society of Portland conducted the surveys (2010 and 2011). Due to the large number of point count stations that had to be surveyed between dawn and midmorning, each survey was conducted over a two-day span. Full surveys were conducted three times per year during the breeding season (May 15-June 31). The following results were based on birds recorded within 50 meters of each Point Count Station. The BES Watershed Revegetation group designated 14 different units to be treated. Revegetation Unit Map: BES 3.14.12 Page 1 Point Count Station Location Map: The above map was created by Herrera and shows where the point count stations are located. Point Count Stations are fairly evenly dispersed around Mt. Tabor in a variety of habitats. -

An Abstract of Nocturnal Bird Call Recognition System for Wind Farm Applications by Selin A. Bastas Submitted to the Graduate Faculty as partial fulfillment of the requirements for the Master of Science Degree in Electrical Engineering The University of Toledo December 2011 Interaction of birds with wind turbines has become an important public policy issue. Acoustic monitoring of birds in the vicinity of wind turbines can address this important public policy issue. The identification of nocturnal bird flight calls is also important for various applications such as ornithological studies and acoustic monitoring to prevent the negative effects of wind farms, human made structures and devices on birds. Wind turbines may have negative impact on bird population. Therefore, the development of an acoustic monitoring system is critical for the study of bird behavior. This work can be employed by wildlife biologist for developing mitigation techniques for both on- shore/off-shore wind farm applications and to address bird strike issues at airports. -

Phylogeography of Finches and Sparrows
In: Animal Genetics ISBN: 978-1-60741-844-3 Editor: Leopold J. Rechi © 2009 Nova Science Publishers, Inc. Chapter 1 PHYLOGEOGRAPHY OF FINCHES AND SPARROWS Antonio Arnaiz-Villena*, Pablo Gomez-Prieto and Valentin Ruiz-del-Valle Department of Immunology, University Complutense, The Madrid Regional Blood Center, Madrid, Spain. ABSTRACT Fringillidae finches form a subfamily of songbirds (Passeriformes), which are presently distributed around the world. This subfamily includes canaries, goldfinches, greenfinches, rosefinches, and grosbeaks, among others. Molecular phylogenies obtained with mitochondrial DNA sequences show that these groups of finches are put together, but with some polytomies that have apparently evolved or radiated in parallel. The time of appearance on Earth of all studied groups is suggested to start after Middle Miocene Epoch, around 10 million years ago. Greenfinches (genus Carduelis) may have originated at Eurasian desert margins coming from Rhodopechys obsoleta (dessert finch) or an extinct pale plumage ancestor; it later acquired green plumage suitable for the greenfinch ecological niche, i.e.: woods. Multicolored Eurasian goldfinch (Carduelis carduelis) has a genetic extant ancestor, the green-feathered Carduelis citrinella (citril finch); this was thought to be a canary on phonotypical bases, but it is now included within goldfinches by our molecular genetics phylograms. Speciation events between citril finch and Eurasian goldfinch are related with the Mediterranean Messinian salinity crisis (5 million years ago). Linurgus olivaceus (oriole finch) is presently thriving in Equatorial Africa and was included in a separate genus (Linurgus) by itself on phenotypical bases. Our phylograms demonstrate that it is and old canary. Proposed genus Acanthis does not exist. Twite and linnet form a separate radiation from redpolls. -

The Kavirondo Escarpment: a Previously Unrecognized Site of High Conservation Value in Western Kenya
Scopus 33: 64-69 January 2014 The Kavirondo Escarpment: a previously unrecognized site of high conservation value in Western Kenya James Bradley and David Bradley Summary In western Kenya, extant woodland habitats and their representative bird species are increasingly scarce outside of protected areas. With the assistance of satellite imagery we located several minimally impacted ecosystems on the Kavirondo Escarpment (0°1.7’ S, 34°56.5’ E), which we then visited to examine the vegetation communities and investigate the avifauna. Despite only a limited effort there, we report several new atlas square occurrences, presence of the local and poorly known Rock Cisticola Cisticola emini and a significant range extension for the Stone Partridge Ptilopachus petrosus. Our short visits indicate high avian species richness is associated with the escarpment and we suggest comprehensive biodiversity surveys here are warranted. Introduction The Kavirondo Escarpment in central-west Kenya is a significant geologic and topographic feature. It straddles the equator, extending over 45 km from east to west, and comprises the northern fault line escarpment of the Kavirondo Rift Valley (Baker et al. 1972). Immediately to the south lie the lowlands of the Lake Victoria Basin and Nyando River Valley, and to the north, the high plateau of the western Kenya highlands (Fig. 1). The escarpment slopes range in elevation from 1200–1700 m at the western end to 1500–2000 m in the east, where it gradually merges with the Nandi Hills. Numerous permanent and seasonal drainages on the escarpment greatly increase the extent of land surface and variation in slope gradients, as well as the richness of vegetation communities. -

The first pass of the framework automatically generates training labels from the input recording itself, while model training and classification is done during the second pass. The proposed framework utilizes a reference directional model for obtaining a feature Keywords: representation called directional embeddings (DE). This reference directional model acts as an acoustic Bird vocalization segmentation model for bird vocalizations and is obtained using the mixtures of Von-Mises Fisher distribution Bioacoustics (moVMF). The proposed DE space only contains information about bird vocalizations, while no informa- Directional embedding tion about the background disturbances is reflected. The framework employs supervised information only for obtaining the reference directional model and avoids the background modeling. Hence, it can be regarded as semi-supervised in nature. The proposed framework is tested on approximately 79,000 vocalizations of seven different bird species. The performance of the framework is also analyzed in the presence of noise at different SNRs. Experimental results convey that the proposed framework performs better than the existing bird vocalization segmentation methods. -
First Records of the Common Chaffinch Fringilla Coelebs and European Greenfinch Carduelis Chloris from Lord Howe Island
83 AUSTRALIAN FIELD ORNITHOLOGY 2004, 2I , 83- 85 First Records of the Common Chaffinch Fringilla coelebs and European Greenfinch Carduelis chloris from Lord Howe Island GLENN FRASER 34 George Street, Horsham, Victoria 3400 Summary Details are given of the first records of two species of finch from Lord Howe Island: the Common Chaffinch Fringilla coelebs and the European Greenfinch Carduelis chloris. These records, from the early 1980s, have been quoted in several papers without the details hav ing been published. My Common Chaffinch records are the first for the species in Australian territory. Details of my records and of other published records of other European finch es on Lord Howe Island are listed, and speculation is made on the origin of these finches. Introduction This paper gives details of the first records of the Common Chaffinch Fringilla coelebs and the European Greenfinch Carduelis chloris for Lord Howe Island. The Common Chaffinch records are the first for any Australian territory and although often quoted (e.g. Boles 1988, Hutton 1991, Christidis & Boles 1994), the details have not yet been published. Other finches, the European Goldfinch C. carduelis and Common Redpoll C. fiammea, both rarely reported from Lord Howe Island, were also recorded at about the same time. Lord Howe Island (31 °32'S, 159°06'E) lies c. 800 km north-east of Sydney, N.S.W. It is 600 km from the nearest landfall in New South Wales, and 1200 km from New Zealand. Lord Howe Island is small (only 11 km long x 2.8 km wide) and dominated by two mountains, Mount Lidgbird and Mount Gower, the latter rising to 866 m above sea level. -
The Relationships of the Hawaiian Honeycreepers (Drepaninini) As Indicated by Dna-Dna Hybridization
THE RELATIONSHIPS OF THE HAWAIIAN HONEYCREEPERS (DREPANININI) AS INDICATED BY DNA-DNA HYBRIDIZATION CH^RrES G. SIBLEY AND Jo• E. AHLQUIST Departmentof Biologyand PeabodyMuseum of Natural History, Yale University, New Haven, Connecticut 06511 USA ABSTRACT.--Twenty-twospecies of Hawaiian honeycreepers(Fringillidae: Carduelinae: Drepaninini) are known. Their relationshipsto other groups of passefineswere examined by comparing the single-copyDNA sequencesof the Apapane (Himationesanguinea) with those of 5 speciesof carduelinefinches, 1 speciesof Fringilla, 15 speciesof New World nine- primaried oscines(Cardinalini, Emberizini, Thraupini, Parulini, Icterini), and members of 6 other families of oscines(Turdidae, Monarchidae, Dicaeidae, Sylviidae, Vireonidae, Cor- vidae). The DNA-DNA hybridization data support other evidence indicating that the Hawaiian honeycreepersshared a more recent common ancestorwith the cardue!ine finches than with any of the other groupsstudied and indicate that this divergenceoccurred in the mid-Miocene, 15-20 million yr ago. The colonizationof the Hawaiian Islandsby the ancestralspecies that radiated to produce the Hawaiian honeycreeperscould have occurredat any time between 20 and 5 million yr ago. Becausethe honeycreeperscaptured so many ecologicalniches, however, it seemslikely that their ancestor was the first passefine to become established in the islands and that it arrived there at the time of, or soon after, its separationfrom the carduelinelineage. If so, this colonist arrived before the present islands from Hawaii to French Frigate Shoal were formed by the volcanic"hot-spot" now under the island of Hawaii. Therefore,the ancestral drepaninine may have colonizedone or more of the older Hawaiian Islandsand/or Emperor Seamounts,which also were formed over the "hot-spot" and which reachedtheir present positions as the result of tectonic crustal movement. -
Immunogenetics and Resistance to Avian Malaria in Hawaiian Honeycreepers (Drepanidinae)
Studies in Avian Biology No. 22:254-263, 2001. IMMUNOGENETICS AND RESISTANCE TO AVIAN MALARIA IN HAWAIIAN HONEYCREEPERS (DREPANIDINAE) SUSAN I. JARVI, CARTER T. ATKINSON, AND ROBERT C. FLEISCHER Abstract. Although a number of factors have contributed to the decline and extinction of Hawai‘i’s endemic terrestrial avifauna, introduced avian malaria (Plasmodium relicturn)is probably the single most important factor preventing recovery of these birds in low-elevation habitats. Continued decline in numbers, fragmentation of populations, and extinction of species that are still relatively common will likely continue without new, aggressive approaches to managing avian disease. Methods of in- tervention in the disease cycle such as chemotherapy and vaccine development are not feasible because of efficient immune-evasion strategies evolved by the parasite, technical difficulties associated with treating wild avian populations, and increased risk of selection for more virulent strains of the parasite. We are investigating the natural evolution of disease resistance in some low-elevation native bird populations, particularly Hawai‘i ‘Amakihi (Hemignathus virens), to perfect genetic methods for iden- tifying individuals with a greater immunological capacity to survive malarial infection. We are focusing on genetic analyses of the major histocompatibility complex, due to its critical role in both humoral and cell-mediated immune responses. In the parasite, we are evaluating conserved ribosomal genes as well as variable genes encoding cell-surface molecules as a first step in developing a better under- standing of the complex interactions between malarial parasites and the avian immune system. A goal is to provide population managers with new criteria for maintaining long-term population stability for threatened species through the development of methods for evaluating and maintaining genetic diver- sity in small populations at loci important in immunological responsiveness to pathogens. -

Corresponding author: María Recuerda, National Museum of Natural Sciences, Calle José Gutiérrez Abascal 2, Madrid 28006, Spain; E-mail: [email protected]. Abstract The common chaffinch, Fringilla coelebs, is one of the most common, widespread and well- studied passerines in Europe, with a broad distribution encompassing Western Europe and parts of Asia, North Africa and the Macaronesian archipelagos. We present a high-quality genome assembly of the common chaffinch generated using Illumina shotgun sequencing in combination with Chicago and Hi-C libraries. The final genome is a 994.87 Mb chromosome- level assembly, with 98% of the sequence data located in chromosome scaffolds and a N50 statistic of 69.73 Mb. Our genome assembly shows high completeness, with a complete BUSCO score of 93.9% using the avian dataset. -
Nomenclature of the Laysan Honeycreeper Himatione [Sanguinea] Fraithii
Peter Pyle 116 Bull. B.O.C. 2011 131(2) Nomenclature of the Laysan Honeycreeper Himatione [sanguinea] fraithii by Peter Pyle Received 21 May 2010 The Apapane Himatione sanguinea is the most abundant extant species of Hawaiian finch (Fringillidae, Drepanidinae) (Pratt 2005, Pyle & Pyle 2009). It occurs throughout high islands of the south-east Hawaiian Islands, where it shows little to no inter-island variation. On Laysan Island, Northwestern Hawaiian Islands, a resident Himatione was first encountered on 3 April 1828 by the naturalist C. Isenbeck (von Kittlitz 1834) and named much later from specimens collected by H. Palmer and G. Munro in June 1891 (Rothschild 1892). While Palmer and Munro were on Laysan they were assisted by George D. Freeth, manager of a guano-mining operation there and an amateur naturalist. In acknowledgement, Rothschild named the new bird Himatione fraithii, based evidently on a miscommunication from Palmer or Munro or an erroneous assumption concerning the spelling of Freeth’s name, which is not mentioned in the description. This taxon, widely known as the Laysan Honeyeater and, later, the Laysan Honeycreeper, became extinct in 1923 (Ely & Clapp 1975, A. Wetmore in Olson 1996). Walter Rothschild was a well-known British zoologist with an avid interest in the birdlife of islands (Rothschild 1983, Olson 2008). He had sent Palmer and other collectors to procure specimens from the Hawaiian Islands in 1890–93 for his private museum in Tring, England. Based upon this collection he published Avifauna of Laysan and the neighbouring islands, with a complete history to date of the birds of the Hawaiian possession in three parts, Part I in August 1893, Part II in November 1893 and Part III in December 1900 (Rothschild 1893– 1900; see Olson 2003).
