Whooping cranes (Grus americana) of the Aransas-Wood Buffalo population migrate twice each year through the Great Plains in North America. Recovery activities for this endangered species include providing adequate places to stop and rest during migration, which are generally referred to as stopover sites. To assist in recovery efforts, initial estimates of stopover site use intensity are presented, which provide opportunity to identify areas across the migration range used more intensively by whooping cranes. We used location data acquired from 58 unique individuals fitted with platform transmitting terminals that collected global position system locations. Radio-tagged birds provided 2,158 stopover sites over 10...

The central Platte River Valley represents a key mid-latitude stopover This dataset supports a contemporary analysis of nocturnal roost selection for sandhill cranes staging along the Platte River during 2003-2007. We explored variation in selection for previously established characteristics of roost sites, including river channel width, vegetation height along the river bank, and distance to nearest disturbance feature. This analysis also included novel environmental factors (yearly estimates of corn near roost sites, nightly temperature, wind speed, and river discharge) and how they may interact with the more established characteristics.

Sandhill cranes are a long-lived bird found in many wetland-rich landscapes across North America. The midcontinent population of sandhill cranes is the largest population in North America, comprising approximately 650,000 individuals. They breed from western Quebec in the east, across the Canadian Arctic and Alaska to northeastern Russia in the west in a variety of ecoregions from Arctic tundra to temperate grasslands. This population winters from southern Oklahoma to northern Mexico, using playa and coastal wetlands. Long-term changes in the Platte River ecosystem pose a potential threat to this population as does declining high-energy food, prompting long-term investigations to better understand current problems...

Numerous wind energy projects have been constructed in the central and southern Great Plains, USA, the main wintering area for midcontinent Sandhill Cranes (Grus canadensis). We assessed exposure of wintering Sandhill Cranes to the current distribution of wind towers in the central and southern Great Plains by estimating overlap using location data from platform transmitting terminals (PTT) collected during winters 1998–2004. Because 90% of wind towers in the region were installed 2004–2013, comparing an established distribution of wind towers (as of January 2014) with pre-construction crane (1998-2004) distribution provides an initial assessment of the midcontinent population’s exposure. Distributions of cranes...

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.

The tabular dataset is a compilation of all historic observations of whooping crane locations up through 1941. Most of the records were obtained from Robert Porter Allen's 1952 report, "The Whooping Crane"; an additional 73 records were added from records found since 1952. Records include source (Allen 1952 [The Whooping Crane, Audubon]or other), location name, county, state or province, country (Canada, US, Mexico), estimated latitude and longitude, year, month, day, life stage (breeding, summering, wintering, migration, unknown), season (spring, summer, fall, winter), observer's name, and logical indicators of nesting, specimen taken, observer identified, or if captive bird. Completeness of each record is variable....
The Aransas-Wood Buffalo population of whooping cranes migrates each year between wintering grounds on the Gulf Coast of Texas through the Great Plains to breeding grounds in northern Alberta and the Northwest Territories lying mostly within Wood Buffalo National Park. The landscape of the Great Plains is undergoing unparalleled change due to oil and wind-energy development and ongoing changes in agriculture. Man-induced change poses potential threats to the population and studies underway seek to fill several major gaps in knowledge needed to make informed decisions on the population’s needs. Currently, minimal data exists for guidance as new sites are selected for wind farms, mining, and oil extraction operations,...

The central Platte River Valley in south-central Nebraska attracts about 450,000 sandhill cranes each spring, forming the principal spring staging area for the midcontinental population. Cranes feed on lands adjacent to the river to acquire fat reserves and other nutrients needed for migration to their breeding grounds (from Siberia to the Canadian Arctic) and for reproduction. At night, the cranes roost in the braided channel of the river, preferring to stand in shallow, slow-moving water, far from potential sources of disturbance. Spring water flows in the central Platte River have been drastically reduced in recent decades as a result of upstream dams that supply water for irrigation. Limited water flows and...
