Tracking Data for Buff-Breasted Sandpiper (Calidris subruficollis)
Available here are tracking data of buff-breasted sandpiper, a shorebird species that breeds only in Arctic Alaska and Canada, spending the winter in the grasslands of Brazil, Uruguay, and Argentina after a lengthy migration. These data were collected to determine range-wide migratory routes, migratory timing, and stopover habitats of this species.
Return to Ecosystems >> Wildlife Tracking Data Collection
USGS Alaska Science Center scientists collect data from wildlife tracking devices to: determine locations of animals throughout their annual cycles, understand patterns of habitat use, quantify time spent on various behaviors, and identify geographic areas repeatedly used by wildlife that may indicate sites of importance to species and populations. Tracking data from other wildlife species can be found at: https://doi.org/10.5066/P9VYSWEH
Tracking Maps

Buff-breasted Sandpiper Tracking Maps
These webpages contain five different types of browse maps and other visualizations of the tracking data.
- Maps (Animated, Static, Interactive, and Google Earth)
- Summary graphs of the data: where, when, duration
- Shorebirds Tagged Animal Movement Explorer interactive visualization tool
- Note: These maps serve only as a depiction of the geographic content of the specific data provided and may be inappropriate for inferences and interpretation outside the intent of the original study. For example, maps may portray only certain ages, sexes, limited numbers of animals or variable tracking duration and start times that may limit inference for other questions. Users are advised to read the publication(s) and data set metadata associated with these maps to understand appropriate use and data limitations.
Data Packages
Argos GPS Satellite Telemetry Data
These data packages contain the data collected from GPS satellite transmitters attached to free-ranging animals. The packages include both raw and processed location and sensor data. The raw data includes data as originally retrieved from the Argos System. The processed data include location data estimated by GPS and the Argos System (Doppler). They have been filtered for location plausibility, and sensor data have been decoded into standard measurement units. For most users, the processed data will be preferred.
NOTE: Processed data contains both plausible (DAF_Filter=0 or Speed_Filter=0) and implausible (DAF_Filter=1 or Speed_Filter=1) locations as indicated by the column “Location_DAF_filter” or “Location_Speed_Filter”. Before using these data, we recommend excluding locations flagged as implausible or apply an alternative filtering method of your choice.
