Habitat Use By Sandhill Cranes Wintering In The Agricultural Landscape Of The Sacramento–San Joaquin River Delta Of California, Gary L. Ivey, Bruce D. Dugger, Caroline P. Herziger, Michael L. Casazza, Joseph P. Fleskes Jan 2023

Habitat Use By Sandhill Cranes Wintering In The Agricultural Landscape Of The Sacramento–San Joaquin River Delta Of California, Gary L. Ivey, Bruce D. Dugger, Caroline P. Herziger, Michael L. Casazza, Joseph P. Fleskes

Proceedings of the North American Crane Workshop

The Sacramento–San Joaquin Delta region of California is an important wintering region for sympatric greater (Grus canadensis tabida) and lesser (G. c. canadensis) sandhill cranes. Basic information about sandhill crane use of habitats in their winter landscape is needed to design a biologically driven conservation strategy. We monitored a sample of radio-tagged birds of each subspecies for 2 winters and conducted foraging counts to document their habitat use. Cranes used the major crops and habitat types that were available in the landscapes surrounding their roost sites and focused most of their foraging in grain crops. We examined habitat selection surrounding …


Whooping Crane Nesting Behavior, Parental Care, And Ecology At Wood Buffalo National Park, Andrew J. Caven, Michael J. Forsberg Jan 2023

Whooping Crane Nesting Behavior, Parental Care, And Ecology At Wood Buffalo National Park, Andrew J. Caven, Michael J. Forsberg

Proceedings of the North American Crane Workshop

We studied Whooping crane (Grus americana) nesting behavior and movement patterns at Wood Buffalo National Park using an instantaneous scan sampling approach. We also photo-documented important behavioral and ecological observations. Data were collected from 2 to 9 June 2023 from before 3:00 to after 22:00 hours. We completed 88 hours of observation and documented nest swapping about every 3.2 hours. The female incubated/brooded 3.3-10.9% more than the male, and the probability of incubation/brooding declined by 49% after the second chick began pipping and by 99% after both chicks had hatched. The eldest chick was successfully provisioned 16 hours and 33 …


Inland Habitat Selection Model For Wintering Whooping Cranes, Karen Tyrell, Kristin Brightwell, Matthew Crane, Wade Harrell, Rosa Palmer, Aaron T. Pearse, Ted Owen Jan 2023

Inland Habitat Selection Model For Wintering Whooping Cranes, Karen Tyrell, Kristin Brightwell, Matthew Crane, Wade Harrell, Rosa Palmer, Aaron T. Pearse, Ted Owen

Proceedings of the North American Crane Workshop

Inland habitat use by wintering Aransas-Wood Buffalo whooping cranes (Grus americana) is expected to increase given projected population growth and observations of some whooping cranes using inland winter habitat in addition to coastal marshes. We developed resource utilization functions using ‘random forests’ to model whooping crane use as a function of environmental covariates considered important for whooping crane use. Covariates associated with distance to cropland, distance to development, and wetness or standing water were the most influential in model prediction. The model estimated that the 50% predicted use contour encompassed 34,925 hectares (ha) and the 95% predicted use contour encompassed …


Mortality Of Fledged Whooping Cranes In The Aransas-Wood Buffalo Population, Kristin Brightwell, Matt Rabbe, Aaron T. Pearse, Ben Bainbridge, Karen Tyrell, Clayton Derby Jan 2023

Mortality Of Fledged Whooping Cranes In The Aransas-Wood Buffalo Population, Kristin Brightwell, Matt Rabbe, Aaron T. Pearse, Ben Bainbridge, Karen Tyrell, Clayton Derby

Proceedings of the North American Crane Workshop

Maintaining accurate mortality records for endangered species is important for guiding management and conservation actions. Mortalities of whooping cranes (Grus americana) in the Aransas-Wood Buffalo Population (AWBP) are documented in published records from 1950 through 2010. This paper documents publicly available records of known mortalities from 2011 through 2023, and updates historic records from 1950 to 2010. Public sightings and telemetry carcass records were restricted to fledged whooping cranes from the AWBP and stratified by confirmed, suspected, and unknown causes across the annual range (i.e., summer, migration, and winter). This mortality update provides more certainty associated with available carcass data …


Differential Habitat Use Of Wintering Whooping Cranes Throughout The Range Of The Eastern Migratory Population, Hillary L. Thompson, Anne E. Lacy, Robert F. Baldwin, Patrick G. R. Jodice Jan 2023

Differential Habitat Use Of Wintering Whooping Cranes Throughout The Range Of The Eastern Migratory Population, Hillary L. Thompson, Anne E. Lacy, Robert F. Baldwin, Patrick G. R. Jodice

Proceedings of the North American Crane Workshop

In 2001, a reintroduced population of whooping cranes (Grus americana), the Eastern Migratory Population (EMP), was established in the eastern United States. There has been no assessment of habitat use of the EMP across the current winter distribution. During 2 winters, we used radio-telemetry to track groups of cranes each for 1 day. We grouped sites into 3 regions, based on natural clustering: north (Illinois, Indiana, Kentucky), central (Tennessee, Alabama), and south (Georgia, Florida, Louisiana). Home ranges decreased in size from north to south (4.9 ± 2.8, 3.1 ± 1.0, and 2.3 ± 0.5 km2, respectively). In the north and …


Comparisons Of Migration Patterns Between Parent-Reared And Costume-Reared Whooping Cranes In The Eastern Migratory Population, 2012–2023, Mary Anderson, Glenn H. Olsen, Susie Dunham, Hillary L. Thompson, Marianne M. Wellington Jan 2023

Comparisons Of Migration Patterns Between Parent-Reared And Costume-Reared Whooping Cranes In The Eastern Migratory Population, 2012–2023, Mary Anderson, Glenn H. Olsen, Susie Dunham, Hillary L. Thompson, Marianne M. Wellington

Proceedings of the North American Crane Workshop

Whooping cranes (Grus americana) have been raised and released into the Eastern Migratory Population (EMP) since 2001. Cranes either were costume-reared and learned their migration route by following an ultralight aircraft, were costume-reared and released in fall near adult cranes (known as direct autumn release), or were parent-reared by captive adult whooping crane pairs and released in the fall near adult whooping cranes. Compared to costume-rearing, parent-rearing encourages conspecific learning prior to release, but needs further research to understand how it may influence post-release behaviors including migration. This study compared the migratory timing and length of parent-reared whooping cranes and …


Temporal Patterns Of Sandhill Crane Use Of The Pecos River Valley, Chaves County, New Mexico, James B. Montgomery Jr. Jan 2023

Temporal Patterns Of Sandhill Crane Use Of The Pecos River Valley, Chaves County, New Mexico, James B. Montgomery Jr.

Proceedings of the North American Crane Workshop

The Pecos River Valley is an important stopover area for both migrating and wintering sandhill cranes (Grus canadensis) in southeastern New Mexico. The combination of shallow impoundments and a playa lake at Bitter Lake National Wildlife Refuge, off-refuge shallow ponds and riverine wetlands, and approximately 20,000 ha of nearby irrigated farmlands in Chaves County provided roosting and foraging areas used by the cranes. Once per week sandhill cranes were counted when departing their roosts during September through April 2005–2024. The fall migration during October and November peaked at 24,431 ± 204 (SE). During this peak period, cranes divided foraging between …


Movement Of Eastern Migratory Whooping Cranes Outside The Nonessential Experimental Population Range, 2002–2024, Nicole M. Gordon, Eleanor A. Laack, Hannah R. Macinnes, Alicia M. Ward, Hillary L. Thompson Jan 2023

Movement Of Eastern Migratory Whooping Cranes Outside The Nonessential Experimental Population Range, 2002–2024, Nicole M. Gordon, Eleanor A. Laack, Hannah R. Macinnes, Alicia M. Ward, Hillary L. Thompson

Proceedings of the North American Crane Workshop

Whooping cranes (Grus americana) are listed as an endangered species under the Endangered Species Act (ESA), with 1 historic migratory population and multiple reintroduced populations. The reintroduced populations, including the Eastern Migratory Population (EMP), are considered nonessential experimental populations (NEP) under section 10j of the ESA. Within the boundaries of the NEP range, whooping cranes are treated with the protection of a threatened species on federal lands but are treated as a species under consideration for listing on private lands. However, if an individual exits the NEP range, they are treated as federally endangered and have the full protections of …

United States Department of Agriculture Wildlife Services: Staff Publications

The northern spotted owl (Strix occidentalis caurina; hereinafter NSO) was listed as “threatened” under the Endangered Species Act in 1990 and population declines have continued since that listing. Given the species’ protected status, any proposed activities on Federal lands that might impact NSO require consultation with U.S. Fish and Wildlife Service and part of that consultation often includes surveys to determine presence and occupancy status of the species in the proposed activity area. The objective of this report is to present study-area specific estimates of the probability of detection for NSO pairs from twelve 2-week seasonal survey periods …

Remembering Clem Klaphake, Don Paseka

Nebraska Bird Review

Clement (Clem) Klaphake passed away on December 30, 2022, from complications of Parkinson’s disease, which he struggled with for several years. He was born in Melrose, Minnesota, in 1943 and grew up working on his parents’ dairy farm, which included the usual menagerie of other farm animals typical of that time. Perhaps it was the routine of milking twice a day, seven days a week, or the impressive scar on his leg from a boar tusk, but Clem was destined to leave the farm and become a life-long educator. ... After getting his degree in 1971, Clem was hired to …

Fall Field Report, August-November 2022, W. Ross Silcock Nov 2022

Fall Field Report, August-November 2022, W. Ross Silcock

Nebraska Bird Review

All in all, this was a fairly uneventful fall season, although even uneventful seasons have their share of oddities and variations from the norm. A noteworthy event was a fire that took out much of the brushy habitat in Carter Canyon, Scotts Bluff Co (see photo on following page). It will be interesting to read upcoming spring reports to see what effect the fire might have had on numbers of birds that frequent brushy areas, like towhees and buntings. Optimistically, fires have attracted rare woodpeckers, with first to arrive Black-backed, which would be a first documented Nebraska record, and typically …

Summer Field Report, June-July 2022, W. Ross Silcock Sep 2022

Summer Field Report, June-July 2022, W. Ross Silcock

Nebraska Bird Review

As always, the summer season produces surprises, and this year was no exception. Surprises fall into different categories, though: genuine statewide rarities, within-state distributional rarities, and, of course in summer, nesting records at new locations, population notes, late and early dates and high numbers, increased knowledge about subspecies in the state, and miscellaneous things of interest. These categories are covered separately below after some housekeeping comments.

“Genuine statewide rarities” were led by the first state record Limpkin found by Karen Kader and seen by many in Sarpy Co. Potential 2nd or so state records were a Mexican Duck in Scotts …

Nebraska Bird Review

The functions and methods of the Nebraska Ornithologists’ Union Records Committee (NOURC) are described in its bylaws (NOURC 2010). The committee’s purpose is to provide a procedure for documenting unusual bird sightings and to establish a list of all documented birds for Nebraska. Species for which the NOURC seeks documentation (NOURC Review List) can be found at the NOU website www.NOUbirds.org. Starting in 2020, the NOURC decided to deal mainly with those species deemed as Accidental on the “Official List of the Birds of Nebraska”. Casual species and out-of- range species are now summarized in the “Seasonal Reports” of the …

Harold W. Manter Laboratory of Parasitology: Library Materials

Great-tailed Grackles (Quiscalus mexicanus) are a social, polygamous bird species whose populations have rapidly expanded their geographic range across North America over the past century. Before 1865, Great-tailed Grackles were only documented in Central America, Mexico, and southern Texas in the USA. Given the rapid northern expansion of this species, it is relevant to study its role in the dynamics of avian blood parasites. Here, 87 Great-tailed grackles in Arizona (a population in the new center of the range) were screened for haemosporidian parasites using microscopy and PCR targeting the parasite mitochondrial cytochrome b gene. Individuals were caught …

Spring Field Report, March-May 2022, W. Ross Silcock Jun 2022

Spring Field Report, March-May 2022, W. Ross Silcock

Nebraska Bird Review

This spring there was a large number of interesting reports generated by active field observers, particularly in the west, where our knowledge continues to be broadened in all aspects. The main takeaway this spring was the inordinate plethora of species that matched or exceeded early arrival dates listed in BONO. There were no fewer than 70 species in this category, involving most families and genera, suggesting some overall influence on migration timing. Perhaps exceptions to these early arrivals were some lingering waterfowl and gulls although terns arrived early. Fully 50 of the early arrivers were passerines, notably including nine species …
