Nest, eggs and young. Like the Osprey and the Bald Eagle, the Golden Eagle is a champion nest-builder, at least in terms of size. Golden Eagles construct a huge platform of sticks, which they line, or pad, with thinner branches and even hair and grasses.hese large birds sometimes build their nests in trees or might use man-made structures, such as an electricity pylon. In Alaska, some Golden Eagles were documented nesting on the ground., but most often they nest on large ledges on cliff faces. Golden Eagles may use the same nest over many breeding seasons.
In their nest high in top of tree A little extra cool info..... Eagles are great parents they take the eggshell and food debris away from the nest. Eagles return to the same nest each year adding nesting materials each time....I read a Golden eagle nest in Scotland was used for 45 years. The largest eagle nest was 91/2 feet wide, 20 feet tall and weighed more than 4,000 pounds. Zoobooks wonderful to read to your kids.
