Calls
For such a powerful bird, the Bald Eagle emits surprisingly weak-sounding calls—usually a series of high-pitched whistling or piping notes. The female may repeated a single, soft, high-pitched note that has been called “unlike any other calls in nature”; apparently this signals her readiness for copulation.
Find This Bird
To find Bald Eagles, head for water, where the birds are likely to be looking for fish. Nationwide, Bald Eagles are most widespread during winter, where they can be found along coasts, rivers, lakes, and reservoirs in many states. They winter in large numbers at some lakes and national wildlife refuges—this list from the National Wildlife Federation is a good place to start.
