From the Abstract: "Results of inland forest surveys for marbled murrelets (Brachyramphus marmoratus) have been used extensively to develop complex land-management plans and answer specific questions about the inland ecology of this threatened species, yet the metric used for these surveys, the detection, is poorly understood. We compared concurrent radar and audio-visual (AV) observations at inland forest sites in Washington and Oregon during 160 mornings in May-July 1997-2000 to determine the realationship between number of murrelets detected with radar at a nest stand and number of detections observed by AV surveyors."
