Because an eagle lives up to 30 years in the wild, it has many years in which to produce offspring.- In the Vancouver area eggs are laid in late March and early April, while in northern Canada and Alaska eggs are laid in May.Only after one eagle was touched by a bystander, did they unlock and fly away. Bald eagles are capable of breeding annually from the age of four, but some of the adults, though paired, seem to choose not to breed.
- An eagle reaches sexual maturity at around four or five years of age.
At that time, the eagle's energies become concentrated on the effort of finding a mate and raising offspring.
Essentially, it's not totally uncommon for eagles to build more than one nest within their nesting territory.
The nest is usually built in a tree, but may be built on a cliff or even on the ground if there are no other options available. They will keep other eagles out of their own nesting territory, which is usually one to two square miles.
Sticks placed in tree forks result in cylindrical or conical shaped nests.
Disk shaped nests are built on the ground or a tree branch which is nearly level. Over the years, some nests become enormous, as much as 9 feet in diameter, weighing two tons.
Bald eagles mate for life, but when one dies, the survivor will not hesitate to accept a new mate.
During breeding season, both birds protect the nest territory from other eagles and predators. In the South it may last from late September through November, while in the Great Plains and Mountain West, it may last from January through March. One way to determine the sex of an eagle is to examine its beak.
Another case reported in a Georgia newspaper article, tells of a locked pair falling to the ground in a golf course.
They were stunned by the fall and remained locked for several hours.
I received an email telling of two talon locked eagles falling into a bush beside a person's home.
