Changes In Winter Whooping Crane Territories And Range 1950–2006, Thomas V. Stehn, Felipe Prieto
Proceedings of the North American Crane Workshop
The whooping crane (Grus americana) winters on the Texas coast primarily in salt marsh habitat. The location of adult whooping crane winter territories during 9 winters between 1950 and 2006 was derived from aerial census data digitized onto infrared photos using GIS software. Range expansion, including changes in distribution and size of winter territories, was analyzed over a 57-year period as flock size increased by 765%. Crane pairs have opted to establish territories in or close to the traditional winter area rather than moving long distances along the coast. This distribution seems based on the preference of the …

Habitat Selection Of Eastern Migratory Whooping Cranes On Their Wintering Grounds, Lara E. A. Fondow, Stanley A. Temple
Proceedings of the North American Crane Workshop
As a monitoring technician for the Whooping Crane Eastern Partnership, I (LEAF) noted that birds in years following release selected wintering habitats that differed greatly from those into which they were initially released. An analysis of the habitat preferences of these birds was needed in order to determine any possible implications to the reintroduction efforts. During the winters of 2004-2005 and 2005-2006, I recorded the locations, habitat use, social associations, and behaviors of all migratory whooping cranes (Grus americana) at known locations in Florida. I used compositional analysis to determine whether habitat use was random at the following …

Mammalian Nest Predation In Mississippi Sandhill Cranes, Rose Butler
Proceedings of the North American Crane Workshop
Low recruitment is the largest challenge facing the recovery of the critically endangered Mississippi sandhill crane (MSC, Grus canadensis pulla). Lack of information on nest predation and the impacts of specific nest predator species hinder effective management to lower nest predation rates. I have completed my first year of a 2-year research project on mammalian predation at the MSC National Wildlife Refuge in Gautier, Mississippi. I aim to identify common nest predators, determine if nest predation rates are higher in certain nesting habitats than others, and if different mammalian predators are more common in certain nesting habitats than others. …

Effects Of Changes In Agriculture And Abundance Of Snow Geese On Carrying Capacity Of Sandhill Cranes During Spring, Aaron T. Pearse, Gary L. Krapu, David A. Brandt
Proceedings of the North American Crane Workshop
The Central Platte River Valley (CPRV) in Nebraska is a key spring staging area for approximately 80% of the midcontinent population of sandhill cranes (Grus canadensis). Evidence that cranes currently are acquiring fat less efficiently than in the past along with a large increase in use of the CPRVby snow geese (Chen caerulescens) led us to evaluate waste-corn availability and index spatial and temporal variation in abundance of sandhill cranes and waterfowl using the CPRV. We also developed a predictive model to assess impact of changes in availability of corn under past, present, and potential future conditions. Predicted …

Whooping Crane Titers In Response To Eastern Equine Encephalitis Immunization, Glenn H. Olsen
Proceedings of the North American Crane Workshop
Eastern equine encephalitis (EEE) is a viral disease caused by a vector-borne alphavirus. Various bird species, primarily native passerines in eastern North America, act as reservoir hosts without suffering clinical disease. When outbreaks occur, the disease is maintained and amplified through a mosquito-wild bird-mosquito cycle. EEE does not cause morbidity or mortality in North American passerines, but does cause mortality in some non-native birds such as pheasants (Phasianus colchicus) and emus (Dromiceius novaehollandiae) (Tengelsen et al. 2001) plus horses (Main 1979) and humans. Between September and December 1984, EEE killed 7 of 39 captive whooping cranes …

Daurian hedgehog (Mesechinus dauuricus) and long-eared hedgehog (Hemiechinus auritus) inhabit Ikh Nart Nature Reserve, Mongolia and both species appear to occupy similar niches. We gathered morphological measurements to test for differences between species and sexes. We hoped to gain insight into the mechanisms that allow the species to coexist. We collected morphometric data from 10 long-eared hedgehogs (6 male, 4 female) and 18 Daurian hedgehogs (10 male, 7 female, and 1 unknown sex). Only total body length in Daurian hedgehogs differed significantly between males and females. Otherwise, we found no significant differences between morphometric measures of …

The toad headed agama (Phrynocephalus versicolor) ranges across the arid steppe regions of southern and western Mongolia and represents one of the most common reptiles in the country. However, few details of the species’ population characteristics exist, which may be important for evaluating population trends and assessing its conservation status. We estimated toad headed agama density in Ikh Nart Nature Reserve, Mongolia based on surveys conducted in the summers (June-September) of 2005, 2006, 2008, and 2009. We conducted surveys in three steppe habitats including tall grassland (n = 7), shrub-steppe (n = 7), and semi-shrub steppe …

Group size is an important variable describing behavioral ecology of animals. A variety of factors such as habitat characteristics, life history, spatio-temporal resource dynamics, population density, predation risk, competition with kin, and social learning often determine group size in large mammals. We studied temporal dynamics of group size in Siberian ibex (Capra sibirica) in a protected area in Mongolia. We measured monthly and yearly variations in typical group size and used the sexual segregation and aggregation statistic to assess sexual segregation. Ibex formed the largest groups in November and smallest groups in July. However, group sizes did not …

First paragraph:
Seit der ersten Mongolisch-Deutschen Biologischen Expedition im Jahre 1962 hat die Erforschung der Avifauna große Fortschritte gemacht, wobei im Zoologischen Institut der Martin Luther Universität Halle-Wittenberg, der Mongolischen Akademie der Wissenschaften und dem Biologischen Institut der Nationaluniversität der Mongolei in Ulaanbaatar umfangreiche Balgund Skelettsammlungen angelegt wurden. Nicht wenige Vogelfunde lagen aber in Form von Nahrungsresten der Greifvögel, Eulen und des Haarraubwildes vor und waren damit nur schwer anzusprechen. So gingen die aufgesammelten Rupfungen und Säugetierrisse zumeist an den Autor, in der Hoffnung, dass sie bestimmt werden können.

We studied the nesting ecology and movement patterns of Eurasian black vultures (Aegypius monachus) nesting in and near Ikh Nart Nature Reserve, Dornogobi Aimag, Mongolia. From 2003 till 2009, we monitored nesting pairs from incubation to fledging and compared nesting success for pairs nesting on rocks and trees. We captured chicks just prior to fledging to apply leg bands and wing tags. We also captured adults in June and attached solar-powered global positioning system (GPS)/satellite telemetry units, leg bands, and wing tags. We collected resighting data on marked birds opportunistically and telemetry data on tagged birds. We monitored …

Measurements of hoof angles, hoof length, toe length, etc., and non-metrical hoof characters of Mongolian Wild Ass carcasses collected in in the South Gobi and in Bordzongijn-Gobi desert are presented. Khulan hooves are flat, wide and look big in relation to the animal’s dimensions. Remarkably is the wide variability in size, angles, in non metric characteristics like shape, color and the occurrence of particularly prolonged hoof wall and flaring walls. For example, toe angles are 52° for front and 54° for hind hooves on average. This measures and the suggested graphical model of the „ideal hoof shape“ can assist to …
