In 2018, artist James Bridle traveled to Cyprus, to film at Limassol Salt Lake, home to an air base and surveillance station jointly run by the NSA and the UK’s GCHQ. The large array of antennae and radars you can see in the distance are used for satellite and radio interception, and reportedly for monitoring distant air space. But the salt lake is also one of the most important wetland areas in the Mediterranean, home to tens of thousands of migrating flamingos each year.
While filming the radar surveillance station, Bridle became interested in the birds. Radar technology can reveal a vast range of unseen activity in nature, including the migration of birds at night. Radar Ornithology uses live weather data from US meteorological facilities. You should be able to see real-time clusters of bird movements at dawn and dusk.
