This 3-year research project was begun in the spring of 2004 to supplement on-going northern goshawk (Accipiter gentiles atricapillus) research being conducted by Tembec Industries Inc. in the Rocky Mountain Forest District of south-eastern British Columbia (BC), Canada. Tembec biologists have been monitoring goshawk activity in the East Kootenays since 2001 and have identified nest areas, tracked nest area occupancy, and monitored reproductive success. However, they have been unable to examine a key stage in the life-history of the goshawks, namely the post-fledging behaviour of young birds. This is a period of time when goshawks young are learning to fly and hunt, but still dependent on their parents for food. During this period they require the forest structure around the nest for cover; however, the exact requirements needed, and the impact of altering this forest structure, is poorly understood. This project was designed to expand and augment Tembec?s current work, and provide a more complete picture of goshawk life history, nest selection, and nesting requirements in BC?s southern interior. Additionally, this project is linked to a broader research project funded by the National Centres for Excellence - Sustainable Forest Management Network (NCE-SFM), which is examining the role of using indicator species, like goshawks, in the sustainable management of forests.
Our specific objectives for this project are to:
1) to describe the movements of fledgling goshawks within the area surrounding the active nest site in order to determine the nature and extent of the post-fledging area; and
2) to examine how the movements of fledgling goshawks within the area surrounding the nest site are impacted by forest structure, fragmentation, and movements of adult birds.
