Interactive Radar Location Map
Click on a Location to See Activity in Your Area!
Click on a radar unit location on the map to see representative trackplots of a migration night and a brief explanation of general activity patterns in the area. Clicking on the season in the legend will also bring up trackplots from all locations that were surveyed during that season. Trackplots shown are 1 hour summaries from a representative migration night near the peak of migration. On the horizontal trackplots, targets (birds and bats that are flying) are colored to indicate their direction of movement according to the color wheel in the upper right hand corner of the trackplot. Targets moving north are colored blue, east are green, south are red, and west are pink. On both horizontal and vertical trackplots, areas with no targets on the trackplots do not necessarily mean there were no targets there, as the radar beam could have been blocked by objects in the environment, reducing detection in specific areas. These areas can be determined by looking at clutter maps or trackplots for the entire season. Site setup involves adjustments to radar settings based on each specific location, and in addition, software updates occur between seasons that make comparisons between sites difficult. Any comparison of activity between sites needs to be made with caution.
