Do bald eagles build cup nests?
Bald eagles nests are platforms made of sticks, added on to each year, they sometimes reach up to a full tonne in weight. These nests are the largest of any bird in North America. They can attain a depth of 13 feet deep and 8 feet across (side to side). They prefer to nest in large tree but will build in a sheltered area on the ground where no trees are available.
