Migrating whooping cranes avoid wind-energy infrastructure when selecting stopover habitat
Electricity generation from renewable-energy sources has increased dramatically worldwide in recent decades. Risks associated with wind-energy infrastructure are not well understood for endangered whooping cranes or other vulnerable crane populations. From 2010 to 2016, we monitored 57 whooping cranes with remote-telemetry devices in the United States Great Plains to determine potential changes inAuthorsAaron T. Pearse, Kristine L. Metzger, David A. Brandt, Jill A. Shaffer, Mark T. Bidwell, Wade C. HarrellHeterogeneity 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 CraneAuthorsAaron T. Pearse, Kristine L. Metzger, David A. Brandt, Mark T. Bidwell, Mary J. Harner, David M. Baasch, Wade C. HarrellDiurnal 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. We used data collected from 42 WhoopingAuthorsDavid M. Baasch, Patrick D. Farrell, Aaron T. Pearse, David A. Brandt, Andrew J. Caven, Mary J. Harner, Greg D. Wright, Kristine L. MetzgerWhooping crane use of riverine stopover sites
Migratory birds like endangered whooping cranes (Grus americana) require suitable nocturnal roost sites during twice annual migrations. Whooping cranes primarily roost in shallow surface water wetlands, ponds, and rivers. All these features have been greatly impacted by human activities, which present threats to the continued recovery of the species. A portion of one such river, the central PlatteAuthorsDavid M.

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 from the AraAuthorsAaron T. Pearse, David A. Brandt, Barry K. Hartup, Mark T.

The Whooping Crane (Grus americana) is a federally endangered species in the United States and Canada that relies on wetland, grassland, and cropland habitat during its long migration between wintering grounds in coastal Texas, USA, and breeding sites in Alberta and Northwest Territories, Canada. We combined opportunistic Whooping Crane sightings with landscape data to identify correlates of WhoopAuthorsNeal D. Niemuth, Adam J. Ryba, Aaron T. Pearse, Susan M. Kvas, David A.

Defining and identifying changes to seasonal ranges of migratory species is required for effective conservation. Historic sightings of migrating whooping cranes (Grus americana) have served as sole source of information to define a migration corridor in the Great Plains of North America (i.e., Canadian Prairies and United States Great Plains) for this endangered species.

Endangered whooping cranes (Grus americana) of the Aransas-Wood Buffalo population migrate through the Great Plains twice each year. Although there is much interest in conservation and management for this species, information regarding characteristics of nocturnal roost sites used during migration has been limited and based largely on incidental observations.
