Haliaeetus leucocephalus
Huge raptor prints on sandbars, usually beside fish scraps.
5–7 in long. Three toes forward, one back (anisodactyl). Deep talon punctures. Rough, bumpy sole texture. Fish remains and whitewash nearby.
Rivers, lakes, coastlines with big trees. Throughout North America.
Diurnal
Fish, waterfowl, carrion
Bald eagles build the largest tree nests of any North American bird.
Should I be concerned?
Keep well back from nests — disturbance is a federal offense in the U.S.
