Bald Eagle Nesting in the Superior National Forest

Abstract

Sixteen years (1959-1974) of bald eagle nesting data representing 102 nests were examined. Nest survey intensity increased in the late 1960''s and was most comprehensive during 1972, 1973, and 1974. Some nests were used for at least 15 years. Most nest trees were white pines, reflecting availability. IN 1974 the number of active and successful nests and young produced were relatively low.
