Available here are tracking data of large-bodied gull species and hybrids (Larus species). These data were collected to better understand the migratory movements of these birds and their role in the dispersal of antibiotic resistant bacteria among areas of Alaska and other regions.
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
Gull Species and Hybrids 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
- 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.

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...Antibiotic Resistant Bacteria in Migratory Birds
Migratory birds, and particularly those using habitats close to human settlements, may be infected with antibiotic resistant bacteria. The USGS is working with public health professionals to understand the role of birds in the maintenance and dispersal of antibiotic resistant bacteria. Additionally, the USGS is investigating how antibiotic resistant bacteria in birds may relate to public and... - Publications
