An investigation of bird migration and mortality at the U.S. Coast Gaurd’s Omega Navigation Station, located in the flood plain of the James River near LaMoure, North Dakota, began in September 1971 following the completion there of the 1,200-foot transmitting tower. The objectives of the study are: 1. To determine the nature of bird migration through the tower area and adjacent regions. 2. To determine the magnitude of bird losses caused by the tower. 3. To determine the influence of weather patterns on bird migration and losses. 4. To develop and evaluate methods for reducing bird losses at towers. This paper summarizes results from the two most recent migration periods--fall 1972 and spring 1973. The study, sponsored by the Northern Prairie Wildlife Research Center, is being conducted in cooperation with North Dakota State University.
