We compared survival, reproduction, and body mass of radio-marked and non-radio-marked spotted owls (Strix occidentalis) to determine if backpack radios influenced reproduction or survival. In most study areas and years, there were no differences (P > 0.05) in survival of males and females or in survival of radio-marked versus banded owls. There was no difference (P = 0.31) in mean mass of owls before and after they had worn radio transmitters. Radio-marked owls produced fewer (P < 0.01) young than did owls that were not radio-marked. Because of the possible relationship between lower productivity and large (> 19g) backpack style transmitters, we recommend that researchers consider the use of smaller transmitters mounted on the tail.
