Food Ecology
Eagle Survival
Types of food
The bald eagle's diet consists of 70-90% fish and 10% small mammals, birds, and aquatic life. The bald eagle is also a carrion which means it feeds on dead and decaying flesh
Obtains food
The bald eagle glides to fish at fast speeds snatching the fish up with it powerful talons
Feeding process
The bald eagle can consume up to a pound of fish in a hour and can go days without eating. The bald eagle protects it food with its wing while it tears the prey apart with small bites of its powerful beak
Stores Food
The bald eagle stores hard to digest food like rabbits in the bald eagles throat called the crop. The stomach breaks this food down overtime
Bald Eagle Reproduction
Bald Eagle Mating

Bald eagles mate when they reach sexual maturity at four to five years of age. The white head and yellow beak signals potential partners.
Once they find a partner, the bald eagle courtship ritual called cartwheeling. The eagles fly high in the air, lock talons, and death-defying plunge to the earth. Right before they hit the ground the eagles disengage and soar to the heavens. After the courtship they find a nest together where they courted and reproduce.
After Mating
Bald eagles lays eggs in January, late February, or March. The eggs (clutch) are incubated for thirty days until they hatch. After hatching the parents hunt for food to feed the young. The young remains in the nest unto they are three months of age.

Epic Bald Eagle Going for the Kill

Bald eagles use the same nest year round and often repair them around the October to February time frame. The bald eagle under close observation build nests with large sticks and springs on white pine. They build their massive nests in tall trees close to the water. The inside of the nest is lined with soft materials for a comfortable environment for baby and is 2-3 inches deep to prevent fatal falls of chicks from the nest. The bald eagles are scared of human and will often abandon their nest when spotting human activity.

Bald Eagle Summary
The Bald Eagle is the emblem of the
United States of America and a
symbol of freedom and great bravery.
This powerful bird survived from being
an endangered species to being only
threatened. I had a great time viewing
this awesome birds beautiful habitat,
amazing features, and cool behaviors.

Juvenile bald eagles are mixture of brown and white; with a black beak in young birds
Voice - Shrill, high pitched, and twittering are common descriptions used for bald eagle vocalizations.
Eyesight - An eagle's eye is almost as large as a human's, but its sharpness is at least four times that of a person with perfect vision.
Longevity (life expectancy) - It's possible for bald eagles in the wild to live longer than thirty years, but the average lifespan is fifteen to twenty years.
Beak - The hook at the tip is used for tearing. Behind the hook, the upper mandible, the edge sharp enough to slice tough skin, over laps the lower, creating a scissors effect.
Talons - Talons are important tools for hunting and defense. Eagles kill their prey by penetrating its flesh with their talons. Eagles can open and close their talons at will.
Skeleton - It weighs about half a pound (250 to 300 grams), and is only 5 or 6 percent of its total weight. The feathers weigh twice that much. Eagle bones are light, because they are hollow. The beak, talons, and feathers are made of keratin.
Respiratory system - Eagles have an external naris on both sides of their beak.

After careful observation I noticed that bald eagles would fly around in circles high in the sky and would sometime fly low towards the lake looking for fish. More often than not they would sit in their nest for long periods of time possibly nesting. Juvenile eagles have grayish color feathers. I seen a couple of eagles on tree branches with their mates just looking around.
