Icf Conservation Education: Bridging Crane Conservation And The International Education Community, Joan Garland, Korie Klink Jan 2010

Icf Conservation Education: Bridging Crane Conservation And The International Education Community, Joan Garland, Korie Klink

Proceedings of the North American Crane Workshop

Education, at multiple levels with audiences in Wisconsin, Florida, Texas, and along the flyways where sandhill (Grus canadensis) and whooping cranes (G. americana) sometimes find themselves in close quarters with people, is the key to protecting North America's cranes. The migration of these birds highlights the dependence of cranes and other wildlife on wetlands along the migration routes. Most of these wetlands are privately owned, so the decisions and conservation outlook of future generations are critical to the survival of these cranes. The International Crane Foundation's (ICF) conservation education programs and materials focus on the importance of …


The Response Of Nesting Mississippi Sandhill Cranes To Growing Season Prescribed Fires, Lauren Billodeaux, Scott Hereford, Sami Gray Jan 2010

The Response Of Nesting Mississippi Sandhill Cranes To Growing Season Prescribed Fires, Lauren Billodeaux, Scott Hereford, Sami Gray

Proceedings of the North American Crane Workshop

Prescribed burning is the most natural and cost effective method of restoring and maintaining the coastal longleaf pine (Pinus palustris) savannah ecosystem that provides feeding and nesting areas for the critically endangered Mississippi sandhill crane (MSC, Grus canadensis pulla). Though growing season burns have shown the greatest results in controlling encroaching shrubs and pines as compared to dormant season burns, burning in the spring and early summer has the potential to disrupt the nesting activities of the MSC population. In order to address both the short and long term needs of this crane population, we make every …


Influence Of Landscape Features Of Wetlands On Nesting Patterns Of Sandhill Cranes In Central Wisconsin, Su Liying, Anne E. Lacy, Jeb A. Barzen Jan 2010

Influence Of Landscape Features Of Wetlands On Nesting Patterns Of Sandhill Cranes In Central Wisconsin, Su Liying, Anne E. Lacy, Jeb A. Barzen

Proceedings of the North American Crane Workshop

We studied the relationship between landscape features and nesting patterns of greater sandhill cranes (Grus canadensis tabida) in central Wisconsin for 3 years. Our study covered 9,840 ha, including about 50% agricultural fields, 20% forest, and 20% wetlands. We analyzed landscape features and nesting patterns at the wetland complex level. Landscape features included size, shape, and type of cover for each wetland complex. Nesting patterns included nesting density and the spatial pattern of the nest locations in a wetland among years. Nest density varied among wetland complexes and years. Mean nest densities in wetlands surveyed were 0.037, 0.033, …


Eastern Equine Encephalitis In Florida Whooping Cranes, Marilyn G. Spalding, Lillian M. Stark Jan 2010

Eastern Equine Encephalitis In Florida Whooping Cranes, Marilyn G. Spalding, Lillian M. Stark

Proceedings of the North American Crane Workshop

Two whooping cranes (Grus americana) that were part of separate projects to reintroduce whooping cranes in eastern North America died suddenly in Florida following a few days of abnormal behavior. The first case was a semi-captive bird on ultralight-led migration from Wisconsin to Florida in December 2004. The second case was a molting 10-year-old male and successful wild breeder that died in May, 2005. Clinical signs were lethargy, abnormal posture, isolation followed by attack by other birds, collapse, heart murmur, and death. Eastern equine encephalitis virus (alphavirus) was isolated from the liver of both birds. The most severe …


Sandhill Cranes Of Coastal British Columbia: Results Of Helicopter Surveys And Preliminary Observations Of Habitat Use, Krista Roessingh, Briony Penn Jan 2010

Sandhill Cranes Of Coastal British Columbia: Results Of Helicopter Surveys And Preliminary Observations Of Habitat Use, Krista Roessingh, Briony Penn

Proceedings of the North American Crane Workshop

A pilot study on sandhill cranes (Grus canadensis) was conducted on the central coast of British Columbia in May 2006, followed by 2 summers of inventory and observation in 2007 and 2008. Fieldwork consisted of gathering local knowledge of crane locales, helicopter and boat surveys, and observations from blinds. We located 29 nest sites on 14 different islands and 1 mainland peninsula, as well as several beach foraging areas and bog roost sites. Observed average crane and nest density in areas of suitable habitat was 0.21/km2 and 0.044/km2, respectively, for 2007 and 2008. Nest and …


Preliminary Wintering Counts And New Locations Of Sandhill Cranes In Mexico, Ingrid Barceló, Edgar G. López, Felipe Chávez-Ramírez Jan 2010

Preliminary Wintering Counts And New Locations Of Sandhill Cranes In Mexico, Ingrid Barceló, Edgar G. López, Felipe Chávez-Ramírez

Proceedings of the North American Crane Workshop

Sandhill cranes (Grus canadensis) undertake a migration twice a year, when more than 400,000 cranes cross the United States from the Arctic of North America and Eastern Siberia to the southwest U.S. and north central Mexico. Although the sandhill crane has been studied intensely, few studies have been done on their Mexican wintering grounds. Little is known about what proportion of the sandhill crane population migrates to Mexico, and there is even less information regarding its dispersion. During winter 2007-2008 we surveyed 30 wetlands in the Chihuahuan Desert ecoregion in northern Mexico, recording presence/absence and number of sandhill …


Evaluating Chemical Deterrence At Two Spatial Scales: The Effectiveness Of Chemical Deterrence For Sandhill Cranes In Cornfields, Anne E. Lacy, Jeb A. Barzen Jan 2010

Evaluating Chemical Deterrence At Two Spatial Scales: The Effectiveness Of Chemical Deterrence For Sandhill Cranes In Cornfields, Anne E. Lacy, Jeb A. Barzen

Proceedings of the North American Crane Workshop

From 2006 through 2008, 9,10 anthraquinone (sold as Avitec™) was used as a deterrent on planted corn seed in Minnesota, Wisconsin, and Michigan. ICF conducted field trials in Wisconsin to determine efficacy of Avitec™ to repel sandhill cranes (Grus canadensis) from germinating corn. We assessed crane use at 2 levels: between and within habitats by crane population surveys to determine crane use of fields, and corn density surveys to assess possible damage within fields. In addition, corn seed samples were taken to assess amount of active ingredient on treated corn seeds in the ground. In 2008 the concentrations …


Sandhill Crane Staging And Whooping Crane Migratory Stopover Dynamics In Response To River Management Activities On The Central Platte River, Nebraska, Usa, Felipe Chavez-Ramirez Jan 2010

Sandhill Crane Staging And Whooping Crane Migratory Stopover Dynamics In Response To River Management Activities On The Central Platte River, Nebraska, Usa, Felipe Chavez-Ramirez

Proceedings of the North American Crane Workshop

The Central Platte River Valley (CPRV) is a critical stopover for migrating whooping cranes (Grus americana) and the most important staging area for sandhill cranes (G. canadensis) in North America. Due to reduced water flows caused by human activities, the Platte River no longer follows its traditional hydrograph which consisted of high spring flows that produced scouring action that eliminated vegetation. To provide adequate crane roosting habitat during stopover and staging periods, annual and woody vegetation has been mechanically cleared on eastern portions of the CPRV since 1980. Staging sandhill crane riverine roosting area has decreased …


Evaluating Propagation Method Performance Over Time With Bayesian Updating: An Application To Incubator Testing, Sarah J. Converse, Jane N. Chandler, Glenn H. Olsen, Charles C. Shafer Jan 2010

Evaluating Propagation Method Performance Over Time With Bayesian Updating: An Application To Incubator Testing, Sarah J. Converse, Jane N. Chandler, Glenn H. Olsen, Charles C. Shafer

Proceedings of the North American Crane Workshop

In captive-rearing programs, small sample sizes can limit the quality of information on performance of propagation methods. Bayesian updating can be used to increase information on method performance over time. We demonstrate an application to incubator testing at USGS Patuxent Wildlife Research Center. A new type of incubator was purchased for use in the whooping crane (Grus americana) propagation program, which produces birds for release. We tested the new incubator for reliability, using sandhill crane (Grus canadensis) eggs as surrogates. We determined that the new incubator should result in hatching rates no more than 5% lower …


Video Surveillance Of Nesting Whooping Cranes, Timothy A. Dellinger, Martin J. Folk Jan 2010

Video Surveillance Of Nesting Whooping Cranes, Timothy A. Dellinger, Martin J. Folk

Proceedings of the North American Crane Workshop

The primary objective of the whooping crane (Grus americana) recovery plan is to establish and maintain 3 selfsustaining wild populations, 1 being a non-migratory Florida population. From 1993 to 2005, we released 289 captive cranes in central Florida, with 31 surviving as of 1 June 2008. From 1995 to 2008 we monitored 68 nests of the Florida population; from those, only 32 chicks hatched and 9 fledged. It often was not apparent why nests failed, and it was not practical to conduct labor-intensive observations at nests; therefore, we collected behavioral data using 12-volt VHS video surveillance cameras at …


Assessing Sandhill Crane Flight Alterations To Power Lines In Southcentral Wisconsin, Kimberly H. Ness, Anne E. Lacy Jan 2010

Assessing Sandhill Crane Flight Alterations To Power Lines In Southcentral Wisconsin, Kimberly H. Ness, Anne E. Lacy

Proceedings of the North American Crane Workshop

We examined how weather and power line type affected abrupt flight alterations of sandhill cranes (Grus canadensis tabida) near electric lines in south-central Wisconsin at 4 U.S. Fish and Wildlife Service fall crane roost count sites near the Wisconsin River in Adams, Columbia, and Iowa counties between September and November 2007. We selected 4 distribution (10-12 m tall, <50 kV) and 2 transmission lines (>20 m tall, >110 kV) in high crane density areas near corn fields within 1.6 km of either the Wisconsin River or local roosting wetland. We recorded frequencies of 3 types of abrupt flight alterations near power lines across 1-2 …


Mississippi Sandhill Crane Chicks Produced From Cryopreserved Semen, Anahid M. Pahlawanian, Megan L. Savoie, Vanessa Peery, Betsy L. Dresser, S. P. Leibo Jan 2010

Mississippi Sandhill Crane Chicks Produced From Cryopreserved Semen, Anahid M. Pahlawanian, Megan L. Savoie, Vanessa Peery, Betsy L. Dresser, S. P. Leibo

Proceedings of the North American Crane Workshop

The Mississippi sandhill crane (MSC, Grus canadensis pulla), 1 of 6 subspecies of sandhill cranes, is classified as critically endangered and was placed on the United States' List of Endangered Fish and Wildlife in 1973. For 13 years starting in 1996, the Audubon Center for Research of Endangered Species (ACRES) and Freeport-McMoran Species Survival Center (SSC) in New Orleans have been contributing to the MSC Recovery Program. Through successful captive propagation of MSCs by use of natural breeding and artificial insemination, more than 150 chicks raised at SSC have been released into the wild population at the MSC National …


The Effects Of Anticoagulant Choice And Sample Processing Time On Hematologic Values Of Juvenile Whooping Cranes, Joan Maurer, Betsy Reichenberg, Cristin Kelley, Barry K. Hartup Jan 2010

The Effects Of Anticoagulant Choice And Sample Processing Time On Hematologic Values Of Juvenile Whooping Cranes, Joan Maurer, Betsy Reichenberg, Cristin Kelley, Barry K. Hartup

Proceedings of the North American Crane Workshop

Blood collected from juvenile whooping cranes (Grus americana) in 2007 and 2008 was divided and placed in either the anticoagulant lithium heparin (LiHep) or tri-potassium ethylenediaminetetraacetic acid (K3EDTA) for diagnostic hematology. Thin smears were prepared from the anticoagulated blood in the field with no delay and in the laboratory after a 4-6-hour delay, and then used to determine differential and total leukocyte counts. Manual heterophil and eosinophil counts were greater in LiHep-treated samples compared to K3EDTA samples (P < 0.05), but there was no difference in the total leukocyte concentration or differential leukocyte counts between anticoagulants based on blood smears prepared with no delay (n = 15). Marked differences were noted in relative heterophil (P < 0.05) and lymphocyte (P < 0.05) counts and total leukocyte (P < 0.05) concentrations of K3EDTA-treated samples processed after the delay (n = 7), suggesting a negative effect on lymphocyte integrity from the anticoagulant. Microscopically, lymphocytes were more intact and easily differentiated from thrombocytes in LiHep-treated samples than K3EDTA, but modest thrombocyte clumping in the LiHep samples was a concern. Either anticoagulant appears adequate for diagnostic hematology in juvenile whooping cranes based on this limited analysis, but blood smears should be prepared immediately under controlled conditions for best results.


Reproductive Health And Performance Of The Florida Flock Of Introduced Whooping Cranes, Marilyn G. Spalding, Martin J. Folk, Stephen A. Nesbitt, Richard Kiltie Jan 2010

Reproductive Health And Performance Of The Florida Flock Of Introduced Whooping Cranes, Marilyn G. Spalding, Martin J. Folk, Stephen A. Nesbitt, Richard Kiltie

Proceedings of the North American Crane Workshop

We retrospectively examined the reproductive parameters of 122 breeding-age whooping cranes (Grus americana) in a reintroduced flock in central Florida from 1992 to 2007. The flock performed poorly when compared with an existing wild flock for all reproductive parameters when controlled for age. Pairs first formed in 1995, nested in 1999, and the first chick fledged in 2002. By 2007, 19 of 63 clutches produced 25 chicks, 9 of which fledged. Drought conditions were ruled out as the sole cause of failure when the drought lessened and productivity increased, but not in all years. We examined adult health, …


A Retrospective Of Whooping Cranes In Captivity, Cindi Barrett, Thomas V. Stehn Jan 2010

A Retrospective Of Whooping Cranes In Captivity, Cindi Barrett, Thomas V. Stehn

Proceedings of the North American Crane Workshop

Early records of captive whooping cranes (Grus americana) were compiled from historical files kept at the Aransas National Wildlife Refuge and other literature. Additional early records of captive whooping cranes in Europe were discovered. Annual numbers and location for all captive whooping cranes were tabulated. Starting in 1949, initial attempts at breeding the species in captivity were conducted opportunistically with a few injured birds captured from the wild. Acaptive breeding flock was started in 1966 at the Patuxent Wildlife Research Center in Laurel, Maryland, from second eggs collected in Canada from the only remaining wild flock. In 1989, the flock …


Changes In Winter Whooping Crane Territories And Range 1950–2006, Thomas V. Stehn, Felipe Prieto Jan 2010

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 Jan 2010

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 Jan 2010

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 Jan 2010

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 Jan 2010

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 …

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.

Upland buzzards occur across Mongolia excluding lush taiga forest and breeds from the Mongolian Altai mountains to the western foothills of the Great Khyangan Mountains. Our field work was conducted during the breeding season of the species in Mongolia from 2001 to 2007. Nest materials of the studied nests contained natural (twigs of elm tree, shrubs, tail, and mane of horse, hair of cows, fur of sheep, goats and camels), and artificial or man-made (cotton, plastic bags, wires, cables, and others) materials. Contents of the nesting materials of the species were differed by location, region and breeding pair’s behavior. A …
