Migratory connectivity describes how populations co-occur throughout the annual cycle. The ability to study migratory connectivity has increased dramatically in the past decade, thanks to technological advances for documenting large-scale animal movement (e.g., GPS tracking, band recoveries, genetics).

The MigConnectivity R package provides a powerful framework for quantifying the strength of migratory connectivity across species, study designs and types of data. It also accounts for the relative abundance of populations across a species’ breeding or non-breeding range and incorporates uncertainty from sources of sampling error. The package’s vignette gives examples and further details.
