This paper describes a mobile research laboratory that has been developed for the Electric Power Research Institute EPRI to monitor local and migratory movements of birds near transmission lines during the day and at night. The mobile laboratory has two small marine radars a fixed-beam type that can be directed vertically to measure the altitude of migrating birds and a surveillance type that can be used to examine the geographical patterns of movement within a range of a few kilometers. A closed circuit television system and a video cassette recorder are used to record information from the fixed-beam radar and the image intensifier. A 16-mm movie camera with an electronic shutter control is used to record the display of the surveillance radar. Although the mobile laboratory was designed to study bird movements in the vicinity of transmission lines, it can also be used to gather valuable information on the patterns of bird movements in the vicinity of airports that have potential bird strike problems.
