Therefore, I identified factors affecting bias and precision of radiotelemetry bearings. I placed transmitters at known locations throughout a study area, crew members estimated bearings to the transmitters without knowing their actual locations, I measured bias and precision of estimated bearings, and I measured possible correlates to bearing error. Overall, estimated bearings to transmitters differed from true bearings by -6.13 degrees to 7.84 degrees (SD = 1.63 degrees). Identified sources influencing bearing bias included:transmitter, receiving-station location, transmission lines, distance from transmitter to receiver, location attempt, time, temperature, and humidity. Identified sources influencing bearing precision included:transmitter, transmission site, habitat, receiving-station location,transmission lines, distance from transmitter to receiver, observer,day, time, humidity,
