Abstract: Northern goshawk (Queen Charlotte subspecies: Accipiter gentilis laingi) inventory and research occurred on Vancouver Island, B.C. from 1994 to 1998. Broadcast surveys, the most effective inventory method known for goshawks, continue to be time-consuming and costly, with a relatively low number of goshawk detections and nest locations per unit of effort. Since 1994, approximately 2,912 broadcast stations resulted in 51 goshawk detections and the location of 19 nest territories. Twelve other goshawk territories were reported by forestry workers and members of the public, 3 were found using radiotelemetry, and another was discovered using the stand-watch inventory technique, increasing the number of currently known goshawk territories on Vancouver Island to 35. Territory occupancy rates appear to vary by year, and may relate to the seral stage of the nesting habitat and to the degree of fragmentation in the surrounding landscape...
