Description:
<p>Habitat use by wintering bald eagles (Haliaeetus leucocephalus) was surveyed systematically along a section of the Missouri River floodplain in southeastern South Dakota. Main centers of eagle use were associated with a communal roost and a food source. During severe windchill conditions and high wind velocities, eagles moved to protected areas. Eagles preferred tree perches, but also perched on cliffs, ice, partially submerged logs, and on the ground. Eagles perched on stout, horizontal branches that were bordered on at least 1 side by open area. Nearly all perches were within 30 m of the river, and 58% of the perched eagles were within 5 m of the river bank. Eagles preferred mature cottonwoods (Populus deltoides). Distribution of bald eagles at a winter site apparently is influenced most by location of food and areas protected from wind.</p>
