Spatial structure in migration routes maintained despite regional convergence among eastern populations of Swainson’s Thrushes

open access: yesMovement Ecology, 2021
Background Migratory connectivity links the different populations across the full cycle and across the species range and may lead to differences in survival among populations.

Population trends in Vermivora warblers are linked to strong migratory connectivity. [PDF]

open access: yesProc Natl Acad Sci U S A, 2018
Significance Identifying drivers of population trends in migratory animals is difficult due to their reliance on different geographic regions throughout the annual cycle.

Migratory insights from singing humpback whales recorded around central New Zealand [PDF]

open access: yesRoyal Society Open Science, 2020
The migration routes of wide-ranging species can be difficult to study, particularly at sea. In the western South Pacific, migratory routes of humpback whales between breeding and feeding areas are unclear. Male humpback whales sing a population-specific

Quantifying the strength of migratory connectivity [PDF]

open access: yesMethods in Ecology and Evolution, 2017
Abstract Technological advancements have spurred rapid growth in the study of migratory connectivity, the linkage of individuals and populations between seasons of the annual cycle. The strength of migratory connectivity is a measure of the co‐occurrence of populations throughout the annual cycle and can be represented by a correlation of the ...

Stable isotope analysis provides new information on winter habitat use of declining avian migrants that is relevant to their conservation [PDF]

open access: yes, 2012
Winter habitat use and the magnitude of migratory connectivity are important parameters when assessing drivers of the marked declines in avian migrants. Such information is unavailable for most species.

Migration ecology of western gray catbirds

open access: yesMovement Ecology, 2021
Background For many songbirds in North America, we lack movement details about the full annual cycle, notably outside the breeding season. Understanding how populations are linked spatially between breeding and overwintering periods (migratory ...

Migratory pathways and connectivity in Asian houbara bustards: evidence from 15 years of satellite tracking. [PDF]

open access: yesPLoS ONE, 2011
Information on migratory pathways and connectivity is essential to understanding population dynamics and structure of migrant species. Our manuscript uses a unique dataset, the fruit of 103 individual Asian houbara bustards captured on their breeding ...

Advances in linking wintering migrant birds to their breeding-ground origins using combined analyses of genetic and stable isotope markers. [PDF]

open access: yesPLoS ONE, 2012
An enduring problem in avian ecology and conservation is linking breeding and wintering grounds of migratory species. As migratory species and populations vary in the degree to which individuals from distinct breeding locales mix on stop-over sites and ...

An evaluation of migration fidelity of Ruby-throated Hummingbirds inferred from stable isotope methods [PDF]

open access: yesPeerJ
Knowledge of spatial connectivity between breeding and non-breeding locations of migratory birds and their breeding site fidelity are important for avian conservation.

Flyway‐scale GPS tracking reveals migratory routes and key stopover and non‐breeding locations of lesser yellowlegs

open access: yesEcology and Evolution, 2022
Many populations of long‐distance migrant shorebirds are declining rapidly. Since the 1970s, the lesser yellowlegs (Tringa flavipes) has experienced a pronounced reduction in abundance of ~63%. The potential causes of the species' decline are complex and
