Model		7.5-21.8 MHz (broadcasting tower) exposure to pigeons and analysis of homing ability
Details		Homing pigeons were released off a radiobroadcasting tower emitting 7.4-21.8 MHz at 150 kWatts. Control birds were released from the same tower when the transmission was turned to another direction. There was no effect of the RF exposure on control vs exposed homing ability. However in birds that were alternated in test and control groups, they did show some ability to sense the RF field after a while and when used as controls in subsequent experiments decreased their vanishing time and deviated from their former (learned) directions. in subsequent studies, it was reported RF did not cause a change in homing ability as compared to non-exposed controls, and although homing speed was decreased in groups homing to RF towers under RF exposure, if pigeons were raised under RF exposure there was no effect of RF from the broadcast tower on homing speed.
