This shows a bald eagle at work building its nest, the nest is made from large tree branches and smaller branches that are woven together. also fresh grasses are used to line the inside of the nest & it gives comfort and acts as an incect repellent.
This shows the structure of an eagle egg. Its amazing to see the difference between a bird formed in an egg shell compared to a human baby that remains attached to the mother via an umbilical cord. The egg houses all the resources that the tiny eaglet requires, like a seed inside a piece of fruit.
Eagle Nest & Habitat "Bald Eagle"
The Bald Eagle prefers habitats near a water source more than most other eagles as its main food is fish, so will live an make nests near seacoasts, rivers, lakes and oceans.
A bald eagle will prefer a water body with a minimum circumference of 11 km (7 miles) or more, and large lakes with an area greater than 10 square kilometres is an ideal habitat for breeding.
Bald eagles prefer hardwood trees, mature coniferous trees where they can perch, roost and build nests.
They will select a tree with good visibility with open structure, not to much canopy cover, but just enough for some protection from the elements and the ability to see prey from this chosen spot, usually the nest will be close to water and far away from any human activity.
One thing an eagle doesn't have to put into consideration when building its nest (eyrie) is protection or hid away from other birds or predators as there is NON, the eagle is the top of its food chain, it has no fear and will attack even large animals for food, like dear / wolfs / rabbits and will sometimes even drown as it will tackle a very large heavy fish and once its claws are dug into the heavy fish and the fish is to heavy for the eagle to fly away with it will be dragged under the water and can drown.
The bald eagle will reside in North America, Canada & Alaska, it makes the largest nest of any bird, and like the "golden eagle" it reuses its nest, repairs it and makes it bigger.
The biggest bald eagle nest can be up to 1 tonne in weight, 12ft x 8ft in size. Its nest (AKA "eyrie") is made from a collection of large branches, smaller branches and they will weave them together, also using fresh grasses and other materials to make a nice soft lining for the nest.
During egg incubation period the male and female eagles will swap duties of sitting on the eggs whilst the other is looking for food and nesting materials. The bald eagle will usually have 1 - 3 eggs per year, like the golden eagle eaglets it is common that only one eaglet will survive and be able to fly, leave the nest and get food for itself.
The average size of a bald eagle egg is approximately 73mm long x 55mm width (breath) or 2.9in x 2.2in.
Well that covers the nests and habitats for the Golden and Bald eagle, these as usually the biggest and most common eagles in North America / Canada & Alaska eagles that feed on fish, mammals, reptiles & other animals.
