Guidelines For Re-Establishing Grey Partridges Through Releasing, Francis Buner, N. J. Aebischer

Galliformes Specialist Group and Affiliated Societies: Reports and Other Materials

In the UK, numbers of grey partridges have declined by over 75% during the last 20 years, and in many parts of the country the species has become locally extinct. Concerns over the magnitude of the decline led the UK Government to place the species on the short list of the UK Biodiversity Action Plan (BAP) for which the Game & Wildlife Conservation Trust was appointed lead partner in 1996. The Grey Partridge Species Action Plan’s targets are to restore numbers from 65,000 pairs in 2005 to 90,000 pairs nationally by 2010, and to expand its 1990 range. Over the …

Effects Of Gregariousness, Conspicuousness, And Novelty On Blue Jay (Cyanocitta Cristata) Learned Avoidance And Stimulus Generalization Of Unpalatable Prey, Joyce M. Dykema

Avian Cognition Papers

I examined a variety of factors hypothesized to be important in the evolution and maintenance of aposematism. Aposematism occurs when prey individuals advertise their toxic or otherwise aversive nature to potential predators via evolved conspicuous signals. I conducted three experiments in which blue jays (Cyanocitta cristata) were allowed to search a printed grayscale pixilated background for grayscale pixilated moths in an open room. I manipulated moth appearance and food reward, and recorded jay predation on the varying moth stimuli. In my first experiment, I repeated Alatalo & Mappes’ (1996) study examining the effects of prey gregariousness, or grouping, …

Galliformes Specialist Group and Affiliated Societies: Reports and Other Materials

Executive Summary

Grouse have long attracted and fascinated people. Their display behaviour, and particularly their traditional communal mating grounds or "leks,” have inspired poetry and folklore as well as scientific theories on sexual selection and the evolution of mating systems. In many parts of their range, grouse hunting still plays a major role in the culture, economy, and subsistence of local communities.

The 2006-2010 Grouse Action Plan provides an overview to the distribution, status and threats to all 18 grouse species worldwide and identifies the most immediate conservation needs. It is a product of the joint expertise of the Grouse …

First Records And First Proven Breeding Of Lesser Grey Shrike, Lanius Minor, In Mongolia, Markus Deutsch, Axel Bräunlich

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

During a trip to the Dzungarian Gobi in southwestern Mongolia, a group of German birdwatchers found several territorial lesser grey shrikes, Lanius minor, and documented an active nest. The species had not previously been recorded from Mongolia. Observations were made near Bulgan gol (Bulgan river; nest coordinates: 46°6’N 91°32’E, 1190 m a.s.l.) in Khovd aimag (Khovd province) on June 24, 2006. Besides two territorial pairs, of which a female could be photographically documented on the nest, at least four more territorial adults were found within an area of about 1.5 km². Based on these records, an abundance …

Biodiversity In Space And Time: Towards A Grid Mapping For Mongolia, Michael Stubbe, Annegret Stubbe, Henrik Von Wehrden, Nayamsuren Batsaikhan, Ravčigijn Samjaa

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

In the future, grid mapping of animal and plant organisms will also play a major role in Mongolia. Based on geographical coordinates, a grid with a resolution of 100 x 100 km was created, which contained 561 cells. Methods and level of current understanding are exemplified by means of two raptors and three mammal species. This establishes a basis for an initial project, which will summarize all breeding occurrences of raptors based on all records, publications, or diary notes. For the first time, the short toed eagle was verified in Mongolia as a breeding bird in 2004. By 2006, ten …

Christmas Bird Counts For North Dakota 2005, Robert N. Randall

The Prairie Naturalist

Twenty areas were included in the North Dakota Christmas Bird Counts. One area that had been included during the previous four years was canceJled due to extreme icy conditions and could not be rescheduled.

There were 216 observers in the field and 41 additional participants counting the birds, which visited their feeders. The field observers were out for about 522.25 hours, 109.75 on foot and 412.5 in cars. Feeder watchers added 97.5 hours to the total. The field observers covered 121.2 miles on foot and 5,648.7 miles in vehicles. Some additional effort was spent in six of the areas where …

Effects Of Predator Removal On Upland Nesting Ducks In North Dakota Grassland Fragments, Kristen D. Chodachek, Michael J. Chamberlain

The Prairie Naturalist

Low nest success rates in the Prairie Pothole Region are attributed mainly to changes in the predator community coupled with reductions in availability of suitable nesting cover. We evaluated effects of removal of mammalian predators on pair density and nest success of ducks nesting on 259 ha sites in northeastern North Dakota during 2001 and 2002. We monitored pair density and duck nests on 10 sites with removal and 10 sites without removal. Overall nest success for both years was greater on trapped (53.4%) than nontrapped sites (28.7%). Pair densities were not affected by predator removal, but did increase across …

K-Means Clustering With Multiresolution Peak Detection, Guanshan Yu, Leen-Kiat Soh, Alan B. Bond

Avian Cognition Papers

Clustering is a practical data mining approach of pattern detection. Because of the sensitivity of initial conditions, k-means clustering often suffers from low clustering performance. We present a procedure to refine initial conditions of k-means clustering by analyzing density distributions of a data set before estimating the number of clusters k necessary for the data set, as well as the positions of the initial centroids of the clusters. We demonstrate that this approach indeed improves the accuracy and performance of k-means clustering measured by average intra to interclustering error ratio. This method is applied to the virtual ecology project to …

Zur Nahrungsökologie Des Uhus Bubo Bubo In Der Mongolei = Feeding Ecology Of The Eagle Owl Bubo Bubo In Mongolia, Thomas Hoffmann, Michael Stubbe, D. Heidecke, R. Piechocki, R. Samjaa, J. Erfurt, D. Sumjaa

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

This paper presents further results on the food ecology of the eagle owl in western Mongolia for the years 1984 to 1992. Additional to the already known sites we investigated two new resting places. At least 27 mammal and 17 bird species were recorded. The results confirm previous studies. Small to medium sized mammals (Cricetidae, Dipodidae, Arvicolidae) dominate the prey of the eagle owl whereas birds and invertebrates are less important.

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), …

In the breeding seasons 2001 to 2003, the avifauna of a study area of about 80 km² in the Selenge Aymag was studied.

The area is characterized by loose groves of elms (Ulmus pumila) and pine trees (Pinus sylvestris), and a chain of barchan dunes which separate the Orkhon valley from the up to 70 m higher situated forest steppe. Steppe species (Stipa spp.) dominate in the south; the northern steppe part is characterized by Caragana bushes (Caragana microphylla, locally C. stenophylla). Between Orkhon Gol and the eastern dunes, dry steppe …

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. …
