The Bald Eagle Nest
He clasps the crag with crooked hands;
Close to the sun in lonely lands,
Ring'd with the azure world, he stands.
The wrinkled sea beneath him crawls;
He watches from his mountain walls,
And like a thunderbolt he falls.

I was traveling the area and spotted this fantastic bridge. Then to the side a saw a large bald eagle landing into its nest. What a fantastic sight, i knew that a cache had to be placed near here for this reason. If you come at the right time you may see the pair or their young. This park and grab will be not night or winter friendly. You may find parking is best on Old Walnut Road.

Lets learn about thier Nest
Who builds the nest?
Male and female eagles build the nest together. Both eagles will bring sticks to add to the nest structure and arrange them within the nest. The nest building activity is part of their pair bonding.
How big is an eagle’s nest?
The average bald eagle nest is 4 to 5 feet in diameter and 2 to 4 feet deep. Each year the adult pair will add 1-2 feet of new material to the nest.
When do eagles build the nest?
Nest building may begin 1-3 months prior to mating and is considered part of the breeding process.
Do eagles use the same nest every year?
Eagles have strong nest site fidelity, meaning they return to the same nest and nesting territory each year. If they successfully produce young at a nest, they are likely to return to that nest year after year. A pair might choose to build a new nest in a different area if their previous nest was unproductive (failed to fledge eaglets) or otherwise proved unsuitable.
Where do bald eagles build their nests?
Bald eagles nest in trees usually choosing the tallest living tree (super canopy) with accessible branches. The nest is built high in the tree below the crown supported by large forked branches near the trunk. In some coastal areas of Alaska and Canada where there are few tall trees, bald eagles will nest on the ground.
What is the nest made of?
A bald eagle nest is constructed of interwoven sticks. The interior is lined with grass, corn stalks, and other material. The bowl filled with soft materials including moss (which may serve as an insect repellent) and the downy feathers from adults.
How long does it take to build a nest?
Initial nest building generally may take 1-3 months. Each breeding season, eagles add material to the nest and may increase the size by up to a foot in height and diameter each year.
How long do they use the nest?
Eagles have nest site fidelity and will use a productive nest year after year adding new material to it each year. A pair of eagles may use a nest until the nest itself becomes so large that the tree can no longer support it. In such a case, the pair might build a nest in the same territory, nearby the previous nest.
Do bald eagles defend territories around their nests?
Yes. The size of the territory defended depends on location and the abundance of food in that area. In an area with abundant food resources, a territory might be quite small, with other eagles’ nests as close as one mile away. Bald eagles will vigorously defend their territories from intrusion by other eagles, particularly during nesting season.
When do bald eagles lay their eggs?
Breeding season varies by latitude.
What color and size are bald eagle eggs?
Bald eagle eggs are off-white in color and average about 3 inches long by 2 inches wide. The average weight is 4-4.5 oz.
How many eggs does a bald eagle lay?
The average clutch (group of eggs) is 1-3. There are reports of 4 eggs in a clutch but such an event is very rare. The eggs are laid one at a time with a separation of a day or two between each egg and hatch in the order they are laid.
How many broods does an eagle have each year?
One brood each year although in southern areas there have be reports of a second brood (a replacement clutch) if the first clutch is lost during incubation.
How long before they hatch?
Incubation for bald eagles is about 35 days. For golden eagles, the incubation period is between 40-45 days. It can take a day for the hatchling to completely break free of the egg after pipping(cracking the egg). Eggs hatch in the order in which they were laid.
How long until the eaglets fledge?
Bald eagles fledge at about 10-14 weeks. Golden eagles fledge in 7-11 weeks. Prior to their first flight, nestlings will flap their wings in the nest or while jumping to an adjacent branch in behavior known as branching.
When do eagles fledge?
Bald eagle young are generally ready to fledge, or take their first flight, by 10-12 weeks of age. Young golden eagles typically fledge around 10 weeks of age.
