Morbidity And Mortality Of Captive Whooping Cranes At The International Crane Foundation 1976-2008, Barry K. Hartup, Jennifer N. Niemuth, Bridget Fitzpatrick, Maureen Fox, Cristin Kelley Jan 2010

Morbidity And Mortality Of Captive Whooping Cranes At The International Crane Foundation 1976-2008, Barry K. Hartup, Jennifer N. Niemuth, Bridget Fitzpatrick, Maureen Fox, Cristin Kelley

Proceedings of the North American Crane Workshop

Tracking the incidence of morbidity and mortality in captive animal collections helps inform husbandry and preventive medicine programs aimed at improving population health and viability. Carpenter and Derrickson (1982) and Olsen et al. (1997) published summary reports of captive whooping crane (Grus americana) mortality that served to identify key problem areas for the primary breeding flock and potential reintroduction programs involving this endangered species. We expanded on this approach and conducted an initial evaluation of morbidity and mortality factors for whooping cranes at the International Crane Foundation (ICF). The purpose of our study was to identify overrepresented factors …


Mississippi Sandhill Crane Conservation Update 2006-2008, Scott G. Hereford, Lauren E. Billodeaux Jan 2010

Mississippi Sandhill Crane Conservation Update 2006-2008, Scott G. Hereford, Lauren E. Billodeaux

Proceedings of the North American Crane Workshop

The Mississippi sandhill crane (MSC, Grus canadensis pulla) is an endangered non-migratory subspecies found in the wild only on and near the Mississippi Sandhill Crane National Wildlife Refuge (MSCNWR) in Jackson County in southeastern Mississippi (Gee and Hereford 1995). The MSC is adapted to the wet pine savannas and open pinelands of the Southeastern Outer Gulf Coastal Plain. By the 1970s, their numbers had decreased to 30-40 individuals including only 5-6 nesting pairs. The firemaintained savannas, once a dominant feature of the landscape, were converted to pine plantations and human development or had degraded to overgrown pine scrub. The …


Home Range Size And Habitat Use Of Mississippi Sandhill Crane Colts, Scott G. Hereford, Tracy E. Grazia, Jereme N. Phillips, Glenn H. Olsen Jan 2010

Home Range Size And Habitat Use Of Mississippi Sandhill Crane Colts, Scott G. Hereford, Tracy E. Grazia, Jereme N. Phillips, Glenn H. Olsen

Proceedings of the North American Crane Workshop

Recruitment in the endangered Mississippi sandhill crane (Grus canadensis pulla) is minimal, with the population of 110 sustained by an annual augmentation of captive-reared juveniles. Suitability of available habitat quality is likely involved in nesting success. Thousands of hectares of pine savanna were restored for crane use, but it is not clear how much was being used by crane families. We used 3-g subcutaneous transmitters to radio-tag 27 colts over 6 years from 1998 to 2002 and 2004 to determine home range and habitat use. Using a hand-held receiver, H-antenna and standard triangulation, location data were collected twice …

Winter Distribution Of Greater Sandhill Cranes Marked At Breeding Areas In California, Oregon, And Washington, Gary L. Ivey, Joseph D. Engler, Martin J. St. Louis, Mark A. Stern, Sean Cross

Proceedings of the North American Crane Workshop

Large numbers of greater sandhill cranes (Grus canadensis tabida) have been banded and color-marked at several important breeding sites in the western U.S. since the late 1960s. Crane color-marking began in the late 1960s at Malheur National Wildlife Refuge (NWR) in eastern Oregon. Crane marking programs were initiated at Sycan Marsh, Summer Lake Wildlife Area (both in south-central Oregon), as well as at Modoc NWR in the mid-1980s. In the mid-1990s, a marking program was initiated at Conboy Lake NWR in south-central Washington. This paper reviews winter records and distribution of marked birds from these sites within the …


Aerial Survey Techniques For Breeding Whooping Cranes, Brian W. Johns Jan 2010

Aerial Survey Techniques For Breeding Whooping Cranes, Brian W. Johns

Proceedings of the North American Crane Workshop

Since the discovery of nesting whooping cranes in Wood Buffalo National Park, the Canadian Wildlife Service has conducted aerial surveys to monitor the population. Aerial survey techniques have varied over the years; however, they have generally followed the techniques used by the author since 1991. The technique involves flying a combination of circular flights and transects over known nesting territories and similar looking marshes likely to contain breeding whooping cranes. These aerial surveys account for nearly 100% of the breeding whooping cranes each year.


Population Status And Geographic Distribution Of Greater Sandhill Cranes In The Mid-Continent Population, Gary L. Krapu, David A. Brandt Jan 2010

Population Status And Geographic Distribution Of Greater Sandhill Cranes In The Mid-Continent Population, Gary L. Krapu, David A. Brandt

Proceedings of the North American Crane Workshop

Number and geographic distribution of greater sandhill cranes (Grus canadensis tabida) in the mid-continent population (MCP) of sandhill cranes were evaluated. G. c. tabida comprised 7 of 133 (5.3%) individuals of 3 subspecies which projects to 31,579 ± 11,661 (SE) individuals in an estimated spring MCP of 600,000 cranes. From a platform transmitting terminal (PTT)-marked sample representative of the geographic distribution of G. c. tabida, 10 of 13 (77%) settled during the breeding season in east-central Canada/Minnesota, including 4 in northwestern Minnesota, 4 in Manitoba (2 at sites near the Minnesota border), and 2 in Ontario. Three …


Sandhill Crane Migration Chronology And Behavior In Northwestern Texas, Carroll D. Littlefield Jan 2010

Sandhill Crane Migration Chronology And Behavior In Northwestern Texas, Carroll D. Littlefield

Proceedings of the North American Crane Workshop

Migrant lesser sandhill cranes (Grus canadensis canadensis) were monitored during 1990-2000 in northwestern Texas as flocks were arriving in autumn and departing in spring; cranes were counted as they passed over an observation point 23 km north of Sudan, Lamb County, Texas. Mean flock size was 34.5 (SD ± 32.6) in autumn and 58.2 (SD ± 45.0) in spring. Most autumn migrants (69.6%) passed in the afternoon, whereas in spring 94% migrated in the morning (1000-1200 hr). Peak period of autumn passage was in October (65%), and in spring all observations were in February-March with the peak usually …


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.


First Breeding Records And Historical Status Of Sandhill Cranes In New England, Scott M. Melvin Jan 2010

First Breeding Records And Historical Status Of Sandhill Cranes In New England, Scott M. Melvin

Proceedings of the North American Crane Workshop

Sandhill cranes (Grus canadensis) nested at 4 sites in south-central Maine between 2000 and 2008 and at single sites in western Massachusetts and west-central Vermont in 2007 and 2008, continuing their eastward range expansion. Of 13 nests observed, 5 were in a lacustrine marsh, 2 were in a riverine marsh, and 2 were in beaver-impounded palustrine marshes, all dominated by cattail (Typha spp.); 2 were in lacustrine fen habitat dominated by sedges (Carex spp.), sphagnum, and leatherleaf (Chamaedaphne calyculata); 1 was in a lacustrine fen dominated by slender sedge (Carex lasiocarpa …

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 …

Behavior Comparisons Of Two Rearing Protocols For Whooping Cranes Raised By Costumed Caregivers And Trained For An Ultralight-Led Migration, Glenn H. Olsen, John B. French

Proceedings of the North American Crane Workshop

Whooping crane (Grus americana) colts are raised at USGS Patuxent Wildlife Research Center, Laurel, Maryland for the first 40-60 days of a chick's life as part of the Whooping Crane Eastern Partnership (WCEP) ultralight-led reintroduction. Numbers raised for WCEP are increasing each year. Up to 2005, we raised whooping crane chicks in the Propagation Building where there are 10 indoor/outdoor pens, 8 full pens, and 2 half-size pens. In 2005 WCEP proposed increasing the number of colts reared to 20-24, numbers beyond the capacity of the facility. To accommodate this greater number of chicks, we modified several outdoor …


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 …


A Retrospective Serological Survey For Infectious Bursal Disease Virus In Free-Ranging Sandhill Cranes In South-Central Wisconsin, Richard R. Sim, Barry K. Hartup Jan 2010

A Retrospective Serological Survey For Infectious Bursal Disease Virus In Free-Ranging Sandhill Cranes In South-Central Wisconsin, Richard R. Sim, Barry K. Hartup

Proceedings of the North American Crane Workshop

A retrospective serosurvey of resident sandhill cranes (Grus candensis pratensis) in Florida suggested Infectious Bursal Disease Virus (IBDV, family Birnaviridae) may have been enzootic there as early as 1992, with 13-63% seroprevalence among age classes and wide geographic distribution of seropositive cranes. The purpose of our study was to describe the prevalence of antibodies to IBDV serotype 2 in a local population of greater sandhill cranes (G. c. tabida) near Briggsville, Wisconsin, that overlapped with resident Florida birds in winter during the same time period. Blood samples were collected June through October between 1996 and 1999 …

Summary Of Sandhill Crane Hunting Seasons In Kansas 1993-2007, David E. Sharp, Helen M. Hands, James A. Dubovsky, John E. Cornely

Proceedings of the North American Crane Workshop

The mid-continent population of sandhill cranes (Grus canadensis) is the largest population of cranes in North America. Hunting seasons for sandhill cranes were closed in 1916 and gradually resumed in Mexico (1940), the United States (1961), and Canada (1964). As knowledge of the biology of cranes and experience with hunting seasons increased, areas in which hunting was permitted expanded, and by 1992 all but 2 states (Nebraska and Kansas) in the U.S. portion of the Central Flyway conducted sport hunting seasons for this population. In 1993 Kansas resumed hunting and initial seasons were limited to specified geographic areas of …

Examination Of Opportunistically Collected Eggs Laid By Whooping Cranes In Florida, Marilyn G. Spalding, Martin J. Folk, Stephen A. Nesbitt

Proceedings of the North American Crane Workshop

We examined 41 whooping crane (Grus americana) eggs or egg remains from 27 nests in the field (n = 4), in the laboratory (n = 33), or incubated by another pair (n = 1), or in captivity (n = 3). Eggs were collected because the nest was in danger (2 eggs, 1 nest), abandoned (5 eggs, 4 nests), or failed to hatch after 34 days (27 eggs, 16 nests), or they were removed for management purposes (5 eggs, 3 nests). Evidence of fertility was found in 18 eggs (12 nests, 44%) of 33 opened. The remainder were either …

Pathology Associated With Lightning Strike And Drowning Mortality Of Whooping Cranes In Florida, Marilyn G. Spalding, Scott Terrell, William B. Brooks

Proceedings of the North American Crane Workshop

Severe thunderstorms associated with a strong front passing through the Gulf Coast of Florida on the night of 1-2 February 2007 resulted in the death of 17 whooping cranes (Grus americana) penned at Chassahowitzka National Wildlife Refuge. Postmortem examination of 4 of the birds revealed saline fluid in lungs and airsacs consistent with drowning. Coagulation necrosis and other histologic changes in kidney, peripheral nerve, airsac membranes, and heart muscle further indicated electrocution and are comparable to other cases of electrocution associated with power-line strikes in Florida. Aspiration of seawater was the most likely cause of death of birds …


Nest Desertion In A Reintroduced Population Of Migratory Whooping Cranes, Richard P. Urbanek, Sara E. Zimorski, Anna M. Fasoli, Eva K. Szyszkoski Jan 2010

Nest Desertion In A Reintroduced Population Of Migratory Whooping Cranes, Richard P. Urbanek, Sara E. Zimorski, Anna M. Fasoli, Eva K. Szyszkoski

Proceedings of the North American Crane Workshop

Reintroduction of an eastern migratory population of whooping cranes (Grus americana) into eastern North America began in 2001. Reproduction first occurred in 2005. Through 2008, eggs were produced in 22 first nests and 2 renests. All first nests failed–50% confirmed due to desertion by the parents and the remaining nest failures also consistent with the pattern of parental desertion. Nest failures were not related to stage of incubation, and they were often synchronous. Temperatures in winter and early spring affected timing of nest failure. An environmental factor such as harassment of incubating cranes by black flies (Simulium …

The Direct Autumn Release Of Whooping Cranes Into The Eastern Migratory Population: A Summary Of The First Three Years, Marianne M. Wellington, Richard P. Urbanek

Proceedings of the North American Crane Workshop

This paper describes methods used in an experimental direct autumn release of captive produced whooping cranes (Grus americana) into a reintroduced migratory population in eastern North America. Eighteen chicks (4 in 2005, 4 in 2006, and 10 in 2007) were eventually released in the vicinity of adult whooping cranes or wild sandhill cranes (G. canadensis). Chicks were reared by costumed aviculturists using strict isolation-rearing techniques at the International Crane Foundation (ICF) and then transferred to Necedah National Wildlife Refuge in central Wisconsin. Initially, 23 chicks were transferred from ICF to Necedah at ages of 17-46 days. …


The Role Of Retrieval And Translocation In A Reintroduced Population Of Migratory Whooping Cranes, Sara E. Zimorski, Richard P. Urbanek Jan 2010

The Role Of Retrieval And Translocation In A Reintroduced Population Of Migratory Whooping Cranes, Sara E. Zimorski, Richard P. Urbanek

Proceedings of the North American Crane Workshop

Beginning in 2001, a reintroduction project was initiated using captive-reared whooping cranes (Grus americana) to establish a migratory flock in eastern North America. From May 2003 to August 2008, 23 of these birds were retrieved and translocated in 15 separate events. These individuals consisted of 14 cranes that had been led to Florida by ultralight aircraft on their first autumn migration (UL) and 9 cranes that had been directly released in autumn in Wisconsin (DAR). Of 104 (86 UL and 18 DAR) reintroduced individuals that eventually departed from their release location, 22% were later retrieved 1-3 times. Lake …
