The Birds That Can Fly A Million Miles, Wings That Can Beat 80 Times A Second

In 2011 an avian radar study managed under the auspices of the U.S. Department of Defense tapped the knowledge of leading U.S. airline, U.S. Air Force, and university experts. Called the Integration and Validation of Avian Radars (IVAR), it found that the eBirdRad mobile radar unit manufactured by Accipiter Radar "could readily track more than 100 targets simultaneously, and could record in real time a host of parameters for each tracked target … [at a] range of at least 6 nautical miles, and up to an altitude of [approximately] 3000 feet."
