Abstract

The article discusses the use of radio telemetry in wildlife research. An aircraft was used to locate a migrating, radio-tagged, sharp-shinned hawk. A 222 MHz four-element Yagi receiving antenna was clamped to the entrance step on the right side of the aircraft, so that it pointed in the direction normal to the direction of flight. The idea was to climb to an appropriate altitude, and fly in large circles to scan a substantial area for the missing bird. While the antenna beam swept across a small town a rush of noise-like sound was heard. This resulted in an investigation of the relationship between a town´s radiation (radio noise) signature and its other attributes, such as economic type, population, geographic concentration, etc
