  • 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.

  • Innovative Foraging by the House Sparrow Passer Domesticus
    46 AUSTRALIAN FIELD ORNITHOLOGY 2005, 22, 46--47 Innovative Foraging by the House Sparrow Passer domesticus NEIL SHELLEY 16 Birdrock Avenue, Mount Martha, Victoria 3934 (Email: [email protected]) Summary This note describes an incidental observation of House Sparrows Passer domesticus foraging for insects trapped within the engine bay of motor vehicles in south-eastern Australia. Introduction The House Sparrow Passer domesticus is commensal with man and its global range has increased significantly recently, closely following human settlement on most continents and many islands (Long 1981, Cramp 1994). It is native to Eurasia and northern Africa (Cramp 1994) and was introduced to Australia in the mid 19th century (Biakers et al. 1984, Schodde & Tidemann 1997, Pizzey & Knight 1999). It is now common in cities and towns throughout eastern Australia (Biakers et al. 1984, Schodde & Tidemann 1997, Pizzey & Knight 1999, Barrett et al. 2003), particularly in association with human habitation (Schodde & Tidemann 1997), but is decreasing nationally (Barrett et al. 2003). Observation On 13 January 2003 at c. 1745 h Eastern Summer Time, a small group of House Sparrows was observed foraging in the street outside a restaurant in Port Fairy, on the south-western coast of Victoria (38°23' S, 142°14' E). Several motor vehicles were angle-parked in the street, nose to the kerb, adjacent to the restaurant. The restaurant had a few tables and chairs on the footpath for outside dining. The Sparrows appeared to be foraging only for food scraps, when one of them entered the front of a parked vehicle and emerged shortly after with an insect, which it then consumed.

  • An Annotated List of Birds Wintering in the Lhasa River Watershed and Yamzho Yumco, Tibet Autonomous Region, China
    FORKTAIL 23 (2007): 1–11 An annotated list of birds wintering in the Lhasa river watershed and Yamzho Yumco, Tibet Autonomous Region, China AARON LANG, MARY ANNE BISHOP and ALEC LE SUEUR The occurrence and distribution of birds in the Lhasa river watershed of Tibet Autonomous Region, People’s Republic of China, is not well documented. Here we report on recent observations of birds made during the winter season (November–March). Combining these observations with earlier records shows that at least 115 species occur in the Lhasa river watershed and adjacent Yamzho Yumco lake during the winter. Of these, at least 88 species appear to occur regularly and 29 species are represented by only a few observations. We recorded 18 species not previously noted during winter. Three species noted from Lhasa in the 1940s, Northern Shoveler Anas clypeata, Solitary Snipe Gallinago solitaria and Red-rumped Swallow Hirundo daurica, were not observed during our study. Black-necked Crane Grus nigricollis (Vulnerable) and Bar-headed Goose Anser indicus are among the more visible species in the agricultural habitats which dominate the valley floors. There is still a great deal to be learned about the winter birds of the region, as evidenced by the number of apparently new records from the last 15 years. INTRODUCTION limited from the late 1940s to the early 1980s. By the late 1980s the first joint ventures with foreign companies were The Lhasa river watershed in Tibet Autonomous Region, initiated and some of the first foreign non-governmental People’s Republic of China, is an important wintering organisations were allowed into Tibet, enabling our own area for a number of migratory and resident bird species.

  • 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.
