Comments on Management:
It may be beneficial to protect or develop buffer strips of trees along waterways *25*. It is important to maintain food sources. This includes encouraging upland species and tailwater fish species such as goldeye, gizzard shad, white bass, and walleye. Also encourage waterfowl by planting food plots and supplying roosting sites. Control water levels to strand fish in shallow pools. Maintain perch trees within 15 m. Of water *31,39*. In NE, foraging was enhanced by maintenence of ice-free water by hydroelectric and steam-plants, and disabling of prey by hydroelectric facilities *65*. A buffer zone of 400-800 m around high-use foraging areas should be maintained *64*. Extensive bank stabilization may be adverse but local bank stabilization can be beneficial *31*. A MI study found that nesting pairs became alert to human activity within 500 m of nest. 75% of flight responses occurred when activity was within 200 m of nest. Vehicles caused the highest response. Response to disturbance increased with disturbance duration, visibility, sound, and number per event. Recommended no human activity within 500-600 m of nests, with a secondary restriced zone of 100-1200 m. *66*. A WA study found that feeding activity in winter was disrupted by recreationals activities, and recommended that foot traffic and motorboats within 400 m of eagles be restricted during the first 5 hours of daylight *75*. Recovery plan recommendations: providing improved habitat, particularly during winter, is the most important means of maximizing survivorship. Steel shot should be used in areas of waterfowl hunting where significant problems with bald eagles are documented. In breeding areas, should (1) maintain 330 feet buffer zone around nest where human access is restricted, (2) maintain 660 feet zone around nest tree where significant changes in landscape are prohibited, (3) preserve 3 or more super-canopy trees within 1/4 mile of each nest for roost and perch sites, (4) artificial nest platforms 25-36 sq feet may be placed in suitable trees with no nests or in trees with dilapidated nests *56*. Artificial nests made of natural materials are beneficial, are most useful when they replace fallen, recently active nests. *68*. In roost areas, should maintain buffer zone of at least 1400 m inland from water's edge, and at least 1360 m of shoreline edge. Tall, large diameter trees should also be protected *63*. A ME study found that starvation of young eagles during their first winter is a major limiting factor of eagle populations, and that food and energy stress may lower the reproductive potential of adults. Supplemental feeding of carrion may temporarily mitigate losses due to starvation, can benefit reintroduction programs by attracting eagles to the area, and can lure eagles away from food sources contaminated by disease or pollution *69*. Decrease risk of raptor electrocution *079*.
