Tracking Data for Yellow-billed Loons (Gavia adamsii)

Science Center Objects

Available here are tracking data of Yellow-billed loons, a species that breeds in coastal areas of western and northern Alaska and adjacent regions of Russia and Canada.  This species winters along the Pacific coasts of North America and Eurasia. These data were collected to better understand the patterns of migratory movements and seasonal use of different regions of Alaska

Return to Wildlife, Fish, and Habitats >> 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:

Yellow-billed Loon tracking maps

These webpages contain four 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

Data Packages

Argos Satellite Telemetry Data

These data packages contain the data collected from 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 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.
