If
building a nest from scratch, the birds carefully select a tree.
They usually select a living tree. They look for a nest tree located
where there dead trees ("snags") nearby. They use the
snags as viewing posts, to keep an eye on the nest when they are
off away from the nest finding food.
If a nest tree remains standing, the eagles often use it for many
years, as long as the nest is secure. The healthier the nest tree
is to start with, the longer it will last. One nest, located in
Ohio, was used for 34 years, until the tree finally blew down. |
