Tracking Data for Blue-winged Teal (Anas discors)

Science Center Objects

Available here are tracking data of Blue-winged Teal, a duck species that breeds throughout much of North America and whose wintering range includes neotropical areas of the Caribbean and Central and South America, thus providing a migratory link between the continents of North and South America. These data were collected to better understand the timing and patterns of migratory movement of Blue-winged Teal as part of a project on the dispersal of avian influenza and other pathogens between North America and the Neotropics by this species.

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:

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

Blue-winged Teal 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.
