Data from: High spatiotemporal overlap in the non-breeding season despite geographically dispersed breeding locations in the eastern whip-poor-will (Antrostomus vociferus)

The eastern whip-poor-will (Antrostomus vociferus) is a Neotropical
migrant that has declined by 70% in recent decades, yet when and where
populations are limited throughout the annual cycle is poorly understood.
We deployed 115 archival GPS tags across a 9.5-degree latitudinal span
(~1000 km; midwestern US) on whip-poor-wills in the summers of 2017 and
2019, and extracted data from 52 tags. The associated .csv file exhibits
the raw movement data extracted from the archival GPS tags, where each row
represents a GPS fix location for a given bird. The columns present are
largely those generated by Lotek, although researchers created a few
columns to aid in identification of birds and downstream data analysis. Of
particular note is the “season” column, where we quantified the likely
behavior (e.g., fall migration) of the individual at the given time and
location. These points essentially represent the migratory tracks from
both fall and spring (when available), including both the breeding and
wintering grounds location. We found that whip-poor-wills circumvented the
Gulf of Mexico, and populations across a large latitudinal gradient came
together in eastern Texas in early October, resulting in decreased
connectivity throughout migration. Breeding-winter migratory connectivity
was low (MC = 0.22 ± 0.12), with extensive overlap of core wintering areas
in southern Mexico and Guatemala. See methods in manuscript for more info.
