David Brandt
David Brandt is a Wildlife Biologist at the USGS Northern Prairie Wildlife Research Center in Jamestown, North Dakota.
Interests include waterfowl ecology and conservation, sandhill cranes, whooping cranes, and conservation and restoration of habitats they depend on. Specific areas of interest and extensive field experience include capture/banding and marking techniques used on medium to large birds, development, and use of new technologies for remotely tracking wildlife, and waterfowl nesting and brood rearing in prairie landscapes. He has conducted research on breeding, migrating, and wintering birds throughout the southern, central, and northern Great Plains and marked and monitored birds that migrate from Mexico to Russia. He has been involved with sandhill cranes and the Central Platte River Valley of Nebraska since the late 1990’s, capturing, marking, and monitoring hundreds of these ancient migrants. Since 2009, research included capturing and marking endangered whooping cranes from the remaining wild population to gather baseline information on migration, habitat use, and important stopover areas throughout their annual cycle. He developed a capture method that enabled the first marking of adult whooping cranes from this population on their wintering grounds. He is also involved in investigating techniques used for establishing high diversity native plantings in degraded landscapes.

Whooping crane stopover habitat use and migration movement data in relation to drought severity, 2010-2022
Wildlife species face threats from climate and land use change, which may exacerbate how extreme climatic events influence population persistence and biodiversity. Migratory waterbirds are especially vulnerable to hydrological drought via reduced availability of surface water habitats. We assessed how whooping cranes, an endangered species in the U.S. and Canada, modified habitat use and migration
Whooping crane migration habitat selection disturbance data and maps
These data and maps were developed to support an effort to understand how whooping cranes (Grus americana) select stopover habitat in the presence of human infrastructure. Location and associated data came from whooping cranes from the Aransas-Wood Buffalo Population, 2010–2016. We marked a sample of 57 whooping cranes with leg-mounted transmitters that acquired locations via the global positionin

Fecundity data for midcontinent sandhill cranes, 2003-2006
Midcontinent sandhill cranes (Antigone canadensis) are the most abundant management population of cranes in the world and have a broad breeding range. Four breeding segments of midcontinent sandhill cranes have been designated based on spatial and temporal distributions throughout the year, including Western Alaska-Siberia (WA-S), Northern Canada-Nunavut (NC-N), West-central Canada-Interior Alaska
Characterization of whooping crane migrations and stopover sites used in the Central Flyway, 2010-2016
These data were developed to support an effort to characterize migration strategies in the U.S. Great Plains and Canadian Prairies and to explore sources of heterogeneity in their migration strategy, including space use, timing, and performance. Data come from locations and other information related to 58 marked Whooping Cranes (Grus americana) from 2010-2016. These data represent basic informatio
Morphological measurements and subspecies of midcontinent sandhill cranes
The midcontinent population of sandhill cranes (Antigone canadensis) has historically been classified into three putative subspecies, but genetic analyses have identified only two genetically distinct subspecies. Previous studies have successfully used morphometrics in combination with an individual's sex to differentiate subspecies of sandhill cranes that had been inferred based on breeding area,

Sandhill crane locations, autumn 2013 migration
Sandhill cranes are a long-lived bird species found in wetland-rich landscapes across North America. This dataset includes locations of 5 cranes during a single autumn migration from their breeding areas in northeastern Asia and south through Alaska, central Canada, and the Great Plains. The migration ends in northern Texas and northern Mexico. These data were used as a case study to highlight the
Sandhill crane phenology at the Platte River, Nebraska, 2001-2007
The central Platte River Valley represents a key mid-latitude stopover. This dataset supports a contemporary analysis of spring migration phenology at the Platte River during 2001-2007. We recorded timing of sandhill crane arrivals and departures from the Platte River.

Developing a photography-based harvest survey to estimate age and subspecies composition of midcontinent sandhill cranes
Midcontinent sandhill cranes (Antigone canadensis) are managed as a single population, but hunting regulations are structured so harvest is targeted towards the more numerous lesser sandhill cranes (A. c. canadensis). However, research indicates that greater sandhill cranes (A. c. tabida) have been disproportionally exposed to harvest at a rate exceeding their proportion within the midcontinent po

Factors influencing autumn–winter movements of midcontinent Mallards and consequences for harvest and habitat management
Annual phenology and distributions of migratory wildlife have been noticeably influenced by climate change, leading to concerns about sustainable populations. Recent studies exploring conditions influencing autumn migration departure have provided conflicting insights regarding factors influencing the movements of Mallards (Anas platyrhynchos), a popular game species.

Population and harvest dynamics of midcontinent sandhill cranes
Sandhill cranes (Antigone canadensis) inhabiting the midcontinent of North America have been hunted since the 1960s under management goals of maintaining abundance, retaining geographic distribution, and maximizing sustainable harvest.

Heterogeneity in migration strategies of the whooping crane
Migratory birds use numerous strategies to successfully complete twice-annual movements between breeding and wintering sites. Context for conservation and management can be provided by characterizing these strategies. Variations in strategy among and within individuals support population persistence in response to changes in land use and climate. We used location data from 58 marked Whooping Crane

Diurnal habitat selection of migrating Whooping Crane in the Great Plains
Available stopover habitats with quality foraging opportunities are essential for migrating waterbirds, including Whooping Crane (Grus americana). Several studies have evaluated habitats used by Whooping Crane for roosting throughout its migration corridor; however, habitats associated with foraging and other diurnal activities have received less attention.
