A hierarchical modelling framework for estimating individual‐ and population‐level reproductive success from movement data Open
Rapidly advancing animal telemetry technologies paired with new statistical models can provide insight into the behaviour of otherwise unobservable free‐living animals. Changes in behaviour apparent from pairing telemetry with statistical …

Revealing migratory path, important stopovers and non-breeding areas of a boreal songbird in steep decline Open
The Olive-sided Flycatcher ( Contopus cooperi ) is a steeply declining aerial insectivore with one of the longest migrations of any North American passerine. We deployed light-level geolocators and archival GPS tags on breeders in boreal A…

Multistate Ornstein-Uhlenbeck approach for practical estimation of movement and resource selection around central places Open
Home range dynamics and movement are central to a species’ ecology and strongly mediate both intra- and interspecific interactions. Numerous methods have been introduced to describe animal home ranges, but most lack predictive ability and …

Current Knowledge and Conservation Status of the Gray-Headed Chickadee in North America Open
The gray-headed chickadee Poecile cinctus is a Holarctic songbird that occurs from northern Europe across Asia and into northwestern North America. Historically, the endemic North American subspecies P. c. lathami ranged across portions of…

Dynamic-Parameter Movement Models Reveal Drivers of Migratory Pace in a Soaring Bird Open
Long distance migration can increase lifetime fitness, but can be costly, incurring increased energetic expenses and higher mortality risks. Stopover and other en route behaviors allow animals to rest and replenish energy stores and avoid …

Local meteorological conditions reroute a migration Open
For migrating animals, realized migration routes and timing emerge from hundreds or thousands of movement decisions made along migration routes. Local weather conditions along migration routes continually influence these decisions, and eve…

Resource partitioning between sympatric seabird species increases during chick‐rearing Open
Partitioning of resources by competing species of seabirds may increase during periods of food shortages and elevated energy demands. Here, we examined whether food resource partitioning (differential use of foraging habitat or the consump…
