Avifaunistische Beobachtungen Im Westchentej, Ulrich Zöphel, Jochen Schulenberg, Wolf-Dieter Busching, Ingolf Todte Jan 2005

Avifaunistische Beobachtungen Im Westchentej, Ulrich Zöphel, Jochen Schulenberg, Wolf-Dieter Busching, Ingolf Todte

Erforschung biologischer Ressourcen der Mongolei / Exploration into the Biological Resources of Mongolia, ISSN 0440-1298

This paper reports the results of bird observations at four study sites with many different habitats in the western Chentej-mountains (forest steppe, taiga) at the end of the spring-migration and the beginning of the breeding time. Altogether 134 bird species were observed, about 107 of which are probably breeding birds. Additional birds were caught using 6 mist-nets. In this way 98 birds of 21 species were caught, measured, and ringed. Furthermore feathers have been collected (molting feathers and near two breeding places of Accipiter nisus).

The bird fauna of the larch forests shows a high species richness (108 species), …

Erforschung biologischer Ressourcen der Mongolei / Exploration into the Biological Resources of Mongolia, ISSN 0440-1298

Here we present a detailed report on bird biodiversity of ecosystems along a North-South transect through Mongolia in 1997whic h serves as a guideline for further research projects and training for students in all Mongolian vegetation zones from northern steppes to southern deserts.

Two hundred fifty-five bird species were observed between 21st of July and 10th of August 1997. The main study sites were located in the North the Selenge-Orchon-basin with meadows and dune woodlands 15 km southern from Suchbaatar, the Middle Gobi-Aimag with desert steppes and sajrs (covered with Ulmus pumila) and in the Bordzongijn-gobi in the South …

Über Die Federmerkmale Der Mongolischen Sakerfalken Falco Cherrug Milvipes Im Vergleich Zu Den Westlichen Sakerfalken Der Unterart F. Ch. Cherrug Und Bemerkungen Über Die Gefiedermerkmale Des “Altaifalken”, Wolf-Dieter Busching

Erforschung biologischer Ressourcen der Mongolei / Exploration into the Biological Resources of Mongolia, ISSN 0440-1298

The different plumage characteristics of the Mongolian Saker Falco cherrug milvipes and the nominate race F. ch. cherrug are discussed. It could be shown that both races are polymorphic. According to Baumgart (1997), Sakers don’t need uniform plumages because they live on nearly blind voles. Due to that there seems to be no selection pressure from victims side. The same phenomenon is observable with Buteo buteo and the typical Mongolian Buteo hemilasius.

Whereas young Sakers of the nominate race cherrug equal more or less already adults, are the differences in the plumage of juv. and ad. milvipes great enough. …

Hawks, Eagles, And Falcons Of North America: Biology And Natural History, Paul A. Johnsgard Jan 1990

Hawks, Eagles, And Falcons Of North America: Biology And Natural History, Paul A. Johnsgard

Paul Johnsgard Collection

I have tried to present an adequate if far from exhaustive survey of the general biology, ecology, and behavior of all the included species, written so as to be understandable to the interested layman as well as useful to the biologist who might be looking for relevant literature citations or trying to deal with a specific question without resorting to extensive library searches. The larger number of species of North American hawklike birds (31, compared to 19 owl species) has required that I keep the individual species accounts substantially shorter. I have excluded the New World vultures from consideration, primarily …


Key To Acanthocephala Reported In Waterfowl, Malcolm Edwin Mcdonald, Jan 1988

Key To Acanthocephala Reported In Waterfowl, Malcolm Edwin Mcdonald,

United States Fish and Wildlife Service: Publications

This is the third part of a continuing series on helminths reported in waterfowl (McDonald 1974, 1981). Coots and moorhens (in Family Rallidae, Order Gruiformes) are included with the Anatidae of Anseriformes. The goal of these studies is complete coverage of waterfowl helminths of the world, although the original incentive-inadequate knowledge of the parasites of North American waterfowl- is less true now. World coverage is desirable because the world distribution of the family, tribes, and even many species of waterfowl often results in world distribution of parasites. The format of this key follows that of the others in the series: …

Introduction Of The Red-Browed Finch To Western Australia, John L. Long Jan 1969

Introduction Of The Red-Browed Finch To Western Australia, John L. Long

Journal of the Department of Agriculture, Western Australia, Series 4

THE Red-browed Finch (Estrilda temporalis) has been established probably since 1958 in orchard clearings in Darling Range gullies east of Perth.

Although some concern has been shown at the introduction of a new species to Western Australia, it appears to be of little economic importance.
