Developing research tools for demographic study of Rhynchophanes mccownii (thick-billed longspurs) Developing research tools for demographic study of Rhynchophanes mccownii (thick-billed longspurs)
Like numerous other North American grassland bird species, Rhynchophanes mccownii (thick-billed longspur) has experienced severe population declines in the last 50 years. Little is known about population-limiting factors, and knowledge gaps limit conservation efforts on the species; however, before research studies aimed at improving conservation and management actions can be developed...

Evidence of longitudinal differences in spring migration strategies of an Arctic-nesting goose Evidence of longitudinal differences in spring migration strategies of an Arctic-nesting goose
During spring, migratory birds are required to optimally balance energetic costs of migration across heterogeneous landscapes and weather conditions to survive and reproduce successfully. Therefore, an individual's migratory performance may influence reproductive outcomes. Given large-scale changes in land use, climate, and potential carry-over effects, understanding how individuals...

Human-induced range expansions result in a recent hybrid zone between sister species of ducks Human-induced range expansions result in a recent hybrid zone between sister species of ducks
Landscapes are consistently under pressure from human-induced ecological change, often resulting in shifting species distributions. For some species, changing the geographical breadth of their niche space results in matching range shifts to regions other than those in which they are formally found. In this study, we employ a population genomics approach to assess potential conservation...

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...

Movement dynamics influence population monitoring and adaptive harvest management strategies in migratory birds Movement dynamics influence population monitoring and adaptive harvest management strategies in migratory birds
Informed population monitoring efforts are essential for sound management of harvested species, and adaptive strategies that provide detailed information to monitoring efforts often require data inputs from complimentary sources. Movement ecology information is seldom directly incorporated into population monitoring or adaptive harvest management strategies, yet can provide valuable...

Using morphological measurements to predict subspecies of Midcontinent sandhill cranes Using morphological measurements to predict subspecies of Midcontinent sandhill cranes
The Midcontinent population of sandhill cranes (Antigone canadensis) has historically been classified into 3 putative subspecies, but genetic analyses have identified only 2 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...
