Mandy Kellner of Kingbird Biological Consultants installs a nesting box near the Downie Marsh. The nesting box is one of up to 50 that will be installed by BC Hydro along the Arrow Lakes Reservoir drawdown zone between Revelstoke and 12 Mile. The boxes, which were by Revelstoke Secondary School wood shop students, are being used to enhance nesting opportunities for birds in the area. Six species of waterfowl – common merganser, hooded merganser, wood duck, common golden-eye, barrow golden-eye, and bufflehead – build their nests in cavities of large coniferous or deciduous trees. The nesting boxes are being installed to provide additional suitable nesting sites for the birds.
