This Eagles nest was build on top of a rock, it gives the eagle great height advantage to spot prey. Some areas there may not be a suitable tree or the rock is higher that surrounding trees, so the eagle gives preference to the height advantage and somewhere close to a water source.
Eagles nest on a cliff / rock face
Sometimes the only place for the eagle is to build their nest on a rock face or Cliff, this will be due to there was no suitable trees in the area, or the rock face has a better advantage point and closer to water or its prey / food source. Eagle need some protection from the eliments, if there is a nice pocket in the rock face its an ideal place to build their nests (eyries)
Sea Eagle with Food
This sea eagle caught this fish from the sea or another water source. Sometimes eagles will try to catch too big an fish and it will drag them under with the weight of the fish and the eagle can drown. lucky for this eagle it got a good catch / meal.
Golden Eaglet and an egg
This picture shows a "Golden eagle eaglet" and a golden eagle egg. When eaglets hatch they are white and fluffy, this keeps them warm, and as they grow and get older they will develop dark feathers.

The eagle will chose a pocket in the cliff / rock face then will line the pocket with branches, grass and sometimes moss to make the nest lining comfy and warm for themselfs and the eaglets.
Eagle Nests & Habitat "Golden Eagle"
Each Eagle nest can be different to another due to the habitat and type of eagle.
A Golden eagle will build a few different nests within its area (territory) it lives in, these territory's can be up to 150 Sq KM in size. The eagles will stick around and mate in these areas unless one of there mates die and then they will move on looking for a new partner and place to live.
Their nests are usually made from tree branches and lined with fresh grasses when in use, the grass helps keep the nest clean, comfortable and acts as an insect repellent.
Some older nests (AKA "eyries") can be up to 2 meters or 6.6ft in diameter and a meter in height (deep). The Golden eagle will keep the nest in good condition when in use by repairing it and eventually it will get bigger the older it gets.
These seem very big nests for a bird, however the biggest nests are made by the "bold eagle" which i will be talking about later.
Eagles will build these nests usually on the highest and most stable tree they can find, this gives them a height advantage so they can see potential prey easy. sometimes the nests become too heavy and the tree branches will break under the weight of the nest.
Other animals, birds & mammals that are too small for an eagle to even bother with or be of interest will use the eagles nest as shelter from their own predators, which are usually food an eagle is interested in, so basically these small animals that an eagle wont normally eat are smart and will take advantage of living close to the eagle as a guardian.
A female Golden eagle will lay one to four eggs (usually two) between the months of January to September (depending on the geographic location). These eggs vary in colour from all white to white with cinnamon or brown spots and blotches on them.
The eagles (male & female swap) will sit on the eggs and start the incubation process as soon as the first egg is laid.
40 to 45 days later the young chick (AKA "eaglet") will hatch from the egg shells, these egg shells are very tough and sometimes help from the mother is required to beak open the egg, and other times the eaglet will die because they can't get out.
when the eaglet is born they are covered in fluffy white down and are fed for approximately fifty days before the young eaglets are developed & strong enough to make their first flight attempts and get their own food. Nature can be very cruel at times and so usually its the oldest eaglet chick from the nest (eyrie) that survives, and the younger eaglets will die without even left the nest. this is because the oldest eaglet will have some days advantage in growth & development so wins the food battle when their mother brings the chicks food to the nest.
In nature the old saying stands true "survival of the fittest". The golden eagle will spend a lot of time looking after their young eaglets as this is the most vulnerable time of the eagles life, once the eaglet can fly and catch its own food they will survive for along time.
The most common death for a young eaglet is starvation, falling out of the nest, been eaten from older eagles.
If a tree is not in the area where an eagle wants to reside then they can also utilise a rock face / cliff, even power lines, anything that has height advantage is preferred.
Also eagle will build there nests near a water source, other trees and high altitude places like around the mountains.
The eagle likes to take height advantage and live in areas where there is some cover (trees, rock / cliff, bush. a good clean fresh water supply is also key to an eagle especially some eagles where their main food source is fish.
Some eagles will also move during long distances during winter months to a warmer climate.
The Golden Eagle is also used as a hunting tool in some parts of the world, like Mongolia people will use an eagle to hunt pests like fox & wolf.
These eagles are trained and accustomed to be around humans, in there natural environment an eagle wouldn't interact with humans, it is only the eagles that are trained from a young age that adapt to living near and working along side humans that can be used for glorified pets / hunting tools.
