Habitat conditions during winter explain movement among subpopulations of a declining migratory bird

Understanding animal movement patterns among subpopulations is crucial for identifying spatiotemporal patterns in animal abundance. Quantifying such movement rates enables a better understanding of population dynamics and how animals decide to move between habitats throughout their range. However, detailed assessments of animal movements among subpopulations are often difficult to obtain with typical capture-mark-recapture methods, limiting our ability to incorporate movement information into conservation planning. We used six years of high-resolution Global Positioning System (GPS) tracking data in a Bayesian multistate model to quantify habitat drivers of monthly intra- (i.e., from one month to the next within a winter) and inter-winter (i.e., from the last month of one winter to the first month of the following winter) movements among eight different subpopulations of a declining migratory bird, the Greenland white-fronted goose (Anser albifrons flavirostris). We found that while Gre..., , , # Data from: Habitat conditions during winter explain movement among subpopulations of a declining migratory bird
