Current Status Of Lesser Sandhill Cranes In Yakutia, Inga Bysykatova, Sergey Sleptsov, Nikolay Vasiliev

Proceedings of the North American Crane Workshop

In Yakutia, the sandhill crane (Grus canadensis canadensis) was considered a common bird in 1957 on the Primorie tundra from the Kolyma River to the Alazeya River. In 1980 the area of the species’ supposed breeding grounds within the Kolyma- Indigirka interfluve comprised 34,600 km2. In 1984-85, the breeding grounds extended west to the Sundrun River, with the total area reaching 49,400 km2. At present, the westernmost sandhill crane range is on the tundra along the lower reaches of the Berelekh River. This region joins the higher density Siberian crane (G. leucogeranus) range, so that the …

Summary Of Sandhill Crane Sport Harvest In Canada 1975–2006, Adrianna C. Araya, Kammie L. Kruse, Keith D. Warner

Proceedings of the North American Crane Workshop

Knowledge of harvest in all areas where the mid-continent population (MCP) of sandhill cranes (Grus canadensis) occurs is critical to managing the population in a sustainable manner. The harvest of MCP in the U.S. has been well documented; however, the harvest in Canada has received less attention. The Canadian Wildlife Service initiated a National Harvest Survey program in 1967, but all sampling variables were not directly comparable until 1975. In this paper, we summarize crane harvest in Canada during the 1975-2006 hunting seasons for Saskatchewan and Manitoba, the 2 provinces with significant sport hunting harvest of sandhill cranes. …

Demoiselle Cranes On Agricultural Lands In The Ukraine, Yuriy Andryushchenko

Proceedings of the North American Crane Workshop

In Eurasia, the western range of the demoiselle crane (Anthropoides virgo) includes the southeast of Ukraine. Here the species nests, forms flying and pre-migrating concentrations, and participates in migration. The number of demoiselle cranes in April-June is about 600-700 individuals (200-250 nesting pairs), and toward the end of the year the population can reach 900-1000 individuals. Of cranes observed during 2000-2008 in the Crimea, 42.3% of pairs (n = 151) nested on agricultural fields: 21.5% on virgin land, 16.1% on cropland, and 3.4% on fallow lands. Principal characteristics of the demoiselle crane nesting locations were wavy relief, scarce herbage, …

Possible Competition Between Waterfowl And Sandhill Cranes At Hiwassee Wildlife Refuge, Tennessee, David A. Aborn

Proceedings of the North American Crane Workshop

As a result of crop planting for waterfowl, numbers of eastern greater sandhill cranes (Grus canadensis tabida) staging and overwintering at the Hiwassee Wildlife Refuge in eastern Tennessee have sharply increased over the last 30-40 years. Peak numbers of wintering cranes have reached 14,000, and this large increase in crane numbers raises the possibility that they may be competing with waterfowl for food and space. I examined broad-scale changes in waterfowl numbers using Christmas Bird Count data, as well as small-scale changes using observations of waterfowl numbers and locations in relation to cranes on individual days. Preliminary results …

Behavior And Habitat Use Of Greater Sandhill Cranes Wintering In East Tennessee, David A. Aborn

Proceedings of the North American Crane Workshop

An increase of eastern greater sandhill cranes (Grus canadensis tabida) stopping over and wintering at the Hiwassee Wildlife Refuge in east Tennessee has led to overcrowding at the refuge, resulting in crane use of private property. Proper management is needed to prevent the cranes from becoming a nuisance, increase the suitability of the refuge for waterfowl, and reduce the likelihood of a disease outbreak. Observations of cranes revealed that cranes spent 83% of their time foraging, alert, or preening. Sandhill cranes foraged primarily in agricultural and grassy fields, whereas mudflats and shallow water were used for preening and …

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 …

Mechanisms Of Habitat Selection Of Reintroduced Whooping Cranes On Their Breeding Range, Kelly J. Maguire, Stanley A. Temple

Proceedings of the North American Crane Workshop

We examined several mechanisms that influenced the habitat selection of reintroduced whooping cranes (Grus americana) on their breeding range in the midwestern United States. Visual observations on 56 whooping cranes from 2001 to 2006 provided accurate locations, habitat descriptions, and bird associations. Location information on each bird was mapped to create home range and to describe the habitat. We found evidence that habitat selection in these cranes resulted from multiple mechanisms, including habitat imprinting, philopatry, site tenacity, intra-specific interactions, and environmental stochasticity. The initial home ranges of all cranes contained habitat similar to that in which they were …

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 …

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 …

Migration Patterns And Movements Of Sandhill Cranes Wintering In Central And Southwestern Louisiana, Sammy L. King, Aaron R. Pierce, Kent R. Hersey, Nicholas Winstead

Proceedings of the North American Crane Workshop

In this study we trapped wintering sandhill cranes (Grus canadensis) in Louisiana and fitted them with satellite transmitters to determine their migration routes. Four of the 6 sandhill cranes with validated locations and a terminus point used the Central Flyway for spring migration; 2 of these 4 (the only 2 for which we have data) also used the Central Flyway for fall migration. Two of the 6 birds used the Mississippi Flyway for spring migration. The results of this study suggest that reintroduced whooping cranes (G. americana) that intermix and migrate with sandhill cranes that winter …

Countability Of Sandhill Cranes In Aerial Surveys, Douglas H. Johnson, John W. Solberg, Courtney L. Amundson

Proceedings of the North American Crane Workshop

Aerial surveys are used to monitor populations of many wildlife species, including sandhill cranes (Grus canadensis). In addition to the usual problems of detectability (involving both availability and perceptibility), aerial surveys of concentrated animals are subject to countability issues; from a rapidly moving aircraft, observers cannot count or accurately estimate the number of animals in a large group. Calibration is sometimes performed in an effort to adjust aerial counts for incomplete detectability and countability by calculating the ratio of animals actually in a group to the number in the group estimated from the aircraft. Here we explore alternative, …

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.

Whooping Crane Migrational Habitat Use Of The Platte River, Nebraska, 2001–2006, Shay Howlin, Clayton Derby, Dale Strickland

Proceedings of the North American Crane Workshop

The Platte River Endangered Species Partnership monitored whooping crane (Grus americana) habitat use along the Platte River between Chapman and Lexington, Nebraska during 11 migration seasons from 2001 to 2006. Daily aerial surveys took place in the morning from 21 March to 29 April in the spring and from 9 October to 10 November in the fall. Decoy detection trials were conducted during each of the 11 survey seasons to calculate actual sample inclusion probabilities for crane groups detected during monitoring flights. The detectability model found significant differences in detectability among strata (upland or channel), contractor, and altitude …

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 …

Development Of The Whooping Crane Tracking Project Geographic Information System, Martha Tacha, Andy Bishop, Justin Brei

Proceedings of the North American Crane Workshop

The highest losses in the Aransas-Wood Buffalo whooping crane population occur during migration. Conservation and recovery of the endangered whooping crane requires understanding of migration patterns to identify important stopover areas and potential sources of mortality or disturbance. We converted the Cooperative Whooping Crane Tracking Project database, containing more than 3 decades of data on whooping crane sightings, to a geographic information system (GIS) to allow coarse scale spatial analyses of whooping crane migration patterns in the United States portion of the Central Flyway. At this writing, the geodatabase contains point data for 1,981 confirmed whooping crane sightings through the …

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 …

Wintering Sandhill Crane Distribution And Habitat Use Patterns At Bosque Del Apache National Wildlife Refuge, New Mexico, Tandi L. Perkins, Leigh H. Fredrickson

Proceedings of the North American Crane Workshop

The single most important factor regulating sandhill crane (Grus canadensis) populations is their ability to carry out annual life cycle events while responding to changing habitat availability and distribution across local, regional, and continental landscapes. Wetland and cropland resource availability and distribution across the landscape have become increasingly unpredictable. Recent changes in farming practices, urbanization, and prevailing drought conditions in New Mexico have transformed and reduced dynamic, heterogeneous landscapes into scattered fragments of the original setting. Concerns are increasing for the cumulative influence of these often irreversible actions in providing the type of resources needed by cranes at …

How Birds Combat Ectoparasites, Dale H. Clayton, Jennifer A. H. Koop, Christopher W. Harbison, Brett R. Moyer, Sarah E. Bush

Harold W. Manter Laboratory of Parasitology: Library Materials

Birds are plagued by an impressive diversity of ectoparasites, ranging from feather-feeding lice, to feather-degrading bacteria. Many of these ectoparasites have severe negative effects on host fitness. It is therefore not surprising that selection on birds has favored a variety of possible adaptations for dealing with ectoparasites. The functional significance of some of these defenses has been well documented. Others have barely been studied, much less tested rigorously. In this article we review the evidence--or lack thereof--for many of the purported mechanisms birds have for dealing with ectoparasites. We concentrate on features of the plumage and its components, as well …

Socially Induced Synchronization Of Every-Other-Day Egg Laying In A Seabird Colony, Shandelle M. Henson, James L. Hayward, J. M. Cushing, Joseph C. Galusha

Faculty Publications

Spontaneous oscillator synchrony has been documented in a wide variety of electrical, mechanical, chemical, and biological systems, including the menstrual cycles of women and estrous cycles of Norway Rats (Rattus norvegicus). In temperate regions, many colonial birds breed seasonally in a time window set by photoperiod; some studies have suggested that heightened social stimulation in denser colonies can lead to a tightened annual reproductive pulse. It has been unknown, however, whether the analog of menstrual synchrony occurs in birdsthat is, whether avian ovulation cycles can synchronize on a daily timescale within the annual breeding pulse. We report every-other-day clutch-initiation and …

Reproductive Success Of American Kestrels (Falco Sparverius) Nesting In Boxes Along An Interstate In Northeastern Tennessee., Jennifer Robertson Powers

Electronic Theses and Dissertations

Nest box programs provide supplemental nest sites for American Kestrels, Falco sparverius. When the availability of nest sites is a limiting factor, the addition of nest boxes can increase local breeding populations. These programs also facilitate the collection of data on breeding kestrels.

This study focuses on an American Kestrel (Falco sparverius) nest box trail along Interstate 26 in northeastern Tennessee during the breeding seasons of 1998, 1999, 2000, 2003, 2004, 2006, and 2009. Productivity measures and reproductive success of nesting birds are provided and compared to other programs. The data are analyzed across years and by …

Fall Field Report, August-November 2009, W. Ross Silcock

Nebraska Bird Review

This was probably the most "normal" fall season in a while, as measured by the small number of late departure dates among summer residents and migrants, early arrival dates among winter residents and migrants, high counts, and rarities. In other words, very little of significance happened. Indeed, in order to provide a spark, I'll even mention three exotics that were reported: a Swan Goose at Fremont 26 November (JRo), a Common Peafowl in Dodge Co 5 August (JWe), and a White-faced Cockatiel caught in a Dixon Co yard 24 August (JJ). None is likely to be a threat to our …

The Fish Crow (Corvus Ossifragus) Reaches Nebraska, Joel G. Jorgensen, Melissa J. Panella, W. Ross Silcock, Kristal J. Stoner

Nebraska Bird Review

The Fish Crow (Corvus ossifragus) was formerly endemic to the southeastern United States where it inhabited coastal areas along the Atlantic and Gulf Coasts (McGowan 2001). Since the early 1900s, the species has steadily expanded north and west along major river systems (McGowan 2001). Fish Crow range expansion has followed a logical pattern, expanding along major rivers in regions close to established populations, in adjacent states to the south and east of Nebraska. The species was first recorded in Missouri in 1964 (Robbins and Easterla 1992). In 1984, Fish Crow was first reported in Kansas and by 1991 …
