Reproductive Ecology of Greater Sandhill Cranes in Nevada
… of nests and chicks (i.e., colts) of greater sandhill cranes (Grus canadensis tabida) in northeastern Nevada, USA, during 2009-2010. We monitored 161 nests and 101 colts and used a maximum-likelihood based approach to test multiple competing hypotheses and estimate daily survival rates, nest …

Migratory Ecology and Movement Patterns of Mid-Continent and Eastern Sandhill Cranes
Sandhill cranes (Antigone canadensis) are long-lived birds with relatively low recruitment rates, making accurate knowledge of abundance and distribution critical for well-informed harvest management. Minnesota is one of few states containing portions of 2 different breeding populations of greater …

Vigilance behavior and land use by sandhill cranes (<i>grus canadensis</i>)
<p>I investigated how vigilance in sandhill crane time budgets changed with behavioral, climatic, and anthropogenic factors. I measured two different postures that could be interpreted as vigilance. Cranes significantly altered the time spent in the alert investigative posture with differences in …

Autumn Foraging and Staging Ecology of Eastern Population Sandhill Cranes (Antigone canadensis tabida)
… behaviour). The Eastern Population of Greater Sandhill Cranes (Antigone canadensis tabida; EP herein) likely began to recolonize Ontario and its historic range starting in the early 1900s and now relies on agricultural grain during migration. Accordingly, ecologists possess little knowledge of …

Below-Ground Food Production in Habitats Utilized by the Rocky Mountain Populations of Greater Sandhill Cranes
… distribution of below-ground foods used by RMP cranes in agricultural fields and wetlands across six annual cycle events in 2006 and 2007 (wintering, spring staging, spring stopover, breeding, post-breeding, and fall staging). Below-ground foods were sampled in sandhill crane foraging habitats …

Sources of Nest Failure in Mississippi Sandhill Cranes, Grus canadensis pulla: Nest Survival Modeling and Predator Occupancy
… of the critically endangered Mississippi Sandhill Crane (Grus canadensis pulla). Lack of information on sources of nest failure hinders effective management to increase recruitment. I examined sources of nest failure for 54 nests at the Mississippi Sandhill Crane National Wildlife Refuge, …

Sandhill crane colt survival and fledging success in northeastern Illinois: the role of age and significance of land cover in an urbanized landscape
The breeding and fledging success of Sandhill Cranes (Grus canadensis spp.) in urban landscapes has been largely unexplored by previous research. I evaluated survival and habitat use of young Greater Sandhill Cranes (G. c. tabida) in northeastern Illinois, where the Eastern Population of cranes and …

Anthraquinone Corn Seed Treatment (Avitec™) As A Feeding Repellent for Ring-Necked Pheasants (Phasianus colchicus) on Newly Planted Corn in Eastern South Dakota
… and Michigan as a seed corn treatment where sandhill cranes (Grus canadensis) have been damaging corn fields by eating the corn seeds shortly after planting. In 2006, a 2-year study was initiated to determine if AvitecTM is an effective pheasant repellent on germinating corn seeds. Wildlife …
