Quantifying rosy-finch migration with stable hydrogen isotope feather markers highlights the need for inter-state collaboration to reach conservation goals Open
The Black Rosy-Finch Leucosticte atrata is a species of conservation concern because their alpine breeding habitat is threatened by climate change and their population size is relatively small. Rosy-finches are notoriously difficult to stu…

The strength of migratory connectivity in Painted Buntings is spatial scale dependent and shaped by molting behavior Open
As migratory species move through the stages of their annual cycle, individuals often display variation in the degree to which they remain in proximity to one another, a phenomenon called migratory connectivity. We show scale dependence in…

Spatial and temporal scale-dependence of the strength of migratory connectivity in a North American passerine Open
Background Migratory connectivity describes the extent to which portions of a migratory population that are spatially associated during one stage of the annual cycle remain associated during other stages of the annual cycle. The strength o…

Integrating tracking and resight data enables unbiased inferences about migratory connectivity and winter range survival from archival tags Open
Archival geolocators have transformed the study of small, migratory organisms but analysis of data from these devices requires bias correction because tags are only recovered from individuals that survive and are re-captured at their taggi…

Empirical tests of habitat selection theory reveal that conspecific density and patch quality, but not habitat amount, drive long‐distance immigration in a wild bird Open
Individuals that disperse long distances from their natal site must select breeding patches with no prior knowledge of patch suitability. Despite decades of theoretical studies examining which cues dispersing individuals should use to sele…

Migratory behavior and winter geography drive differential range shifts of eastern birds in response to recent climate change Open
Significance Over the past half century, populations of neotropical migratory birds in North America have plummeted while populations of resident species have largely remained stable. We show that resident and migratory birds in eastern No…
