Bald Eagle Nest Size report

bald eagle nestRecently, a local headline in Washington made many people excited about a pair of Bald Eagles nesting in the National Botanic Garden in the downtown area. That was the first time since 1947. The scientific name of the bald eagle is Haliaeetus leucocephalus. It is a mistake to be called a bald eagle. "Bald" means white in ancient English. The white feathers on the head and tail of the bald eagle are born after birth. It will only be generated in the 5th year.

The bald eagle is the national bird of the United States. The employees of the National Botanic Garden first noticed the new nest in January, and they observed the pair of bald eagles flying in and out of the tree branch. Their activity patterns changed by the end of January: one stayed in the bald eagle's nest, the other went out for food. Experts point out that this change in behavior pattern indicates that bald eagles are hatching eggs.

To protect this young family, the National Botanical Garden has centered on the eagle's nest. It has designated an area of 660 feet in radius as a restricted area because human activities, noise, and disturbance may cause sea eagles to abandon their nests.

Bald Eagle Basics

Bald eagles are unique eagle species in North America. On June 20, 1782, the U.S. Congress passed a resolution and legislation to select the Bald Eagle as the national bird of the United States. These Native Americans believed that the Bald Eagle was a messenger of messages between gods and people. Dancers in Indian song and dance celebrations use the paws of bald eagles as part of their logo. Usually, in traditional ceremonies, people will use the feathers of the Bald Eagle as the symbol of the throne, fan, waist cushion, and headdress. As an important symbol of American culture, the Bald Eagle has many interesting stories and facts.

In the 18th century, it was estimated that there were more than 100,000 pairs in the country, but by 1963, bald eagles were on the verge of extinction due to long-term hunting, loss of habitat, a decline in water quality, and the abuse of chemicals. After long-term protection and efforts, its number has rebounded to about 11,000 pairs. Although the Bald Eagle is no longer on the list of endangered species, it is still a protected bird.

Bald Eagle Nest Size Guide

The life span of bald eagles can reach as long as 30 years in the wild. They always follow monogamy. The same couple of bald eagles often return to the same nest year after year and continue to build them. After multiple seasons, the huge size of the nest becomes a symbol of their love. Bald eagles build the largest bird nests in North America.

There is a huge eagle's nest in Vermillion, Ohio, where a pair of bald eagles have been used for more than 30 years, with a diameter of 2.7 meters, a height of 3.6 meters, and an estimated weight of close to 2 tons. The largest recorded nest in Florida was 9.5 feet in diameter, 20 feet deep, and weighed almost three tons.

A typical bald eagle's nesting landscape would be forested and include rivers or lakes that offer shallow water areas. These landscapes provide basic needs: water to drink, fish to eat, forest trees for shelter and a place to raise young, and perches for hunting and resting.

Bald Eagle Nest Average Size

  1. A typical nest will range from 1.8 to 3 meters (6-10 feet) in diameter and about 1.8 to 3 meters (6 to 10 feet) high.
  2. The nest cavity, where the eggs are laid, will be about 30 to 40 centimeters (12 to 16 inches) in diameter and about 10 centimeters (4 inches) deep.
  3. The size of bald eagle nests varies considerably because bald eagles reuse their nest. First-year nests are usually smaller, and the nest size will increase each year as bald eagles reuse the nest and add new material, which adds one to two feet of height.
  4. The size of a nest is based on how much the tree can hold. Bald eagles typically build a nest in the tallest living tree in their territory with suitable branches. Some pairs need to rebuild their nest almost from scratch if winds and bad weather have damaged it.
  5. In forested areas, bald eagles often select the tallest trees with limbs strong enough to support a nest that can weigh more than 1,000 pounds.
  6. Bald eagles nest in mature or old-growth trees, dead trees, cliffs, and rock promontories. They choose to nest in tall, sturdy conifers that stick up above the forest canopy, providing easy flight access and good visibility.
