Description: In the wild, bald eagles can live for up to 20-30 years, and adult male bald eagles reach about 90 centimeters (36 inches) in length and 6-9 pounds in weight, while the slightly larger adult females can reach 108 centimeters (43 inches) in length and weigh 10-15 pounds.
Habitats: Bald eagles inhabit North America from the north of Alaska and Canada down to the Mexico border. They live in forested areas near lakes and reservoirs with plenty of fish to eat. They also live in the forested areas near coastlines similar to the Cannon Beach area.
Nesting: There are several bald eagle nests near Haystack Rock. Bald eagles lay 2, (some times 1-3), white nearly spherical eggs. Both parents incubate the eggs for 34 to 36 days. After the chicks hatch, parents bring food to the nest for 10 to 12 weeks, until the fledglings take their first flights. At Haystack, bald eagle sightings are common in the late spring and early summer, presumably due to an increased need for prey to feed their chicks.
Diet: Bald eagles consume both coastal and freshwater species of fish. Along America’s Pacific Coast where Cannon Beach is located, bald eagles tend to eat salmon and trout. They’re also known for eating other seabirds and waterfowl and can be seen preying on the birds living on Haystack Rock in Cannon Beach.
Tide Pool Tidbits:
Bald eagles are kleptoparasites: they are often found harassing other birds of prey until the other bird drops its catch so the bald eagle can steal it. Bald eagles have also been observed snatching the prey of other birds right out of their talons. These bold birds will also steal fish from mammals (including humans that are fishing!).
Bald eagles have been observed playing with objects such as plastic bottles or sticks, sometimes passing the objects from one bald eagle to another as they fly in groups.
Juvenile bald eagles lack the “bald” plumage of the adult; they instead have a more mottled plumage containing a mix of brown and white feathers. Because of this different appearance, juvenile bald eagles are often confused for adult golden eagles.
