Whooping crane use around Air Force Bases in Oklahoma, 2017-2022 Whooping crane use around Air Force Bases in Oklahoma, 2017-2022
The Aransas-Wood Buffalo population of whooping cranes migrates through the U.S. Great Plains twice annually, moving between wintering areas along coastal Texas and summering areas in and around Wood Buffalo National Park, Canada. These birds primarily migrate within a roughly 300-km-wide corridor that spans areas in Texas, Oklahoma, Kansas, Nebraska, South Dakota, North Dakota, and...
Whooping crane stopover habitat use and migration movement data in relation to drought severity, 2010-2022 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...

The Aransas-Wood Buffalo population of Grus americana (Linnaeus, 1758; whooping cranes) migrates through the U.S. Great Plains, encountering places substantially altered by human activity. Using telemetry data from 2017 to 2022, we investigated whooping crane migration behavior around U.S. Air Force bases in Oklahoma. Our study focused on potential collision risks between whooping cranes...

Developing a photography-based harvest survey to estimate age and subspecies composition of midcontinent sandhill cranes 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...

Factors influencing autumn–winter movements of midcontinent Mallards and consequences for harvest and habitat management 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. We determined...

Balancing future renewable energy infrastructure siting and associated habitat loss for migrating whooping cranes Balancing future renewable energy infrastructure siting and associated habitat loss for migrating whooping cranes
The expansion of human infrastructure has contributed to novel risks and disturbance regimes in most ecosystems, leading to considerable uncertainty about how species will respond to altered landscapes. A recent assessment revealed that whooping cranes (Grus americana), an endangered migratory waterbird species, avoid wind-energy infrastructure during migration. However, uncertainties...

Whooping crane (Grus americana) migratory stopovers can vary in length from hours to more than a month. Stopover sites provide food resources and safety essential for the completion of migration. Factors such as weather, climate, demographics of migrating groups, and physiological condition of migrants influence migratory movements of cranes (Gruidae) to varying degrees. However, little...

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. Some biologists have raised concerns regarding harvest sustainability because sandhill cranes have lower reproductive rates than other game birds. We...

Heterogeneity in migration strategies of the whooping crane 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...

Mortality in Aransas-Wood Buffalo Whooping Cranes: Timing, location, and causes Mortality in Aransas-Wood Buffalo Whooping Cranes: Timing, location, and causes
For long-lived species with low fecundity rates, population growth rate can be sensitive to changes in annual survival. Understanding where, when, and why animals die provides useful information for prioritizing conservation practices designed to increase survival. As part of a satellite tracking study, we identified 19 confirmed and suspected deaths of Whooping Cranes of various ages...
