(1969). Ground Nesting During a visit to the islands in early July 1970, Bald Eagles were frequently observed near a frail nest-structure located near the top of a dead 30- foot spruce tree on a IVi-acre island. Remnants of an old nest, apparently blown down during the previous winter, were scattered below the tree. The reconstructed nest in the tree contained new nesting material but no eggs. While searching for duck nests on adjacent islands on 3 July 1970, we found an eagle's nest platform on the ground of a 1-acre island about 300 yards from the tree nest. The ground nest was.
