Tracking Data for Red-throated Loons (Gavia stellata) Active
Available here are tracking data of Red-throated Loons, a species that breeds in coastal areas throughout Alaska and 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 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
Red-throated Loon 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
- Loons 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 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.
NOTE: Processed data contains both plausible (DAF_Filter=0) and implausible (DAF_Filter=1) locations as indicated by the column “Location_DAF_filter”. Before using these data, we recommend excluding locations flagged as implausible or apply an alternative filtering method of your choice.

USGS Alaska Science Center Wildlife Tracking Data Collection
Understanding the short- and long-distance movements of wildlife is critical for a wide variety of ecological research questions and management decisions. Since the mid-1980s, the USGS Alaska Science Center has used information from telemetry devices on wildlife species to determine locations of animals throughout their annual cycles, understand patterns of habitat use, quantify time spent on...Loon Research
Scientists at the USGS Alaska Science Center have conducted research on Alaska’s three loon species since the late 1970s. Loons rely on freshwater lakes for nesting habitat and fish and invertebrates inhabiting lakes and marine ecosystems for food. All three loon species in Alaska occur within the National Petroleum Reserve-Alaska (NPR-A) on Alaska’s northern coast. Research by the USGS is... - Data

Movements and habitat use of loons for assessment of conservation buffer zones in the Arctic Coastal Plain of northern Alaska
Oil and gas development in the Arctic Coastal Plain, Alaska, may pose threats to wildlife. Management guidelines within the National Petroleum Reserve-Alaska dictate buffer zones for coastal wildlife habitat and for breeding and foraging sites of yellow-billed loons (YBLOs; Gavia adamsii), a species of conservation concern. However, few data exist to assess the value of these buffer zones for YBAuthorsSharon Poessel, Brian D. Uher-Koch, John M. Pearce, Joel A. Schmutz, Todd E. Katzner, David C. Douglas, Vanessa R. von Biela, Autumn-Lynne HarrisonInternational migration patterns of Red-throated Loons (Gavia stellata) from four breeding populations in Alaska
Identifying post-breeding migration and wintering distributions of migratory birds is important for understanding factors that may drive population dynamics. Red-throated Loons (Gavia stellata) are widely distributed across Alaska and currently have varying population trends, including some populations with recent periods of decline. To investigate population differentiation and the location of miAuthorsSarah E. McCloskey, Brian D. Uher-Koch, Joel A. Schmutz, Thomas F.

The U.S. Geological Survey (USGS) Changing Arctic Ecosystems (CAE) initiative informs key resource management decisions for Arctic Alaska by providing scientific information on current and future ecosystem response to a changing climate. From 2010 to 2014, a key study area for the USGS CAE initiative has been the Arctic Coastal Plain of northern Alaska. This region has experienced rapid warming duAuthorsBrian D. Uher-Koch, Joel A.
