how big is an eagles nest

June 28, 2026

An eagle’s nest is huge compared to most other birds’ nests. For bald eagles, a typical nest is roughly 5–6 feet (1.5–1.8 m) across and about 2–4 feet (0.6–1.2 m) deep, and the very largest can reach around 10 feet wide, over 20 feet deep, and weigh as much as a small car or several thousand pounds over many years of reuse.

Quick Scoop

Short answer to “how big is an eagles nest”

Most bald eagle nests: about 5–6 ft wide, 2–4 ft deep.

Big, old nests: can exceed 7 ft across and 6 ft or more deep.

Extreme record nests: around 9–10 ft across, about 20–22 ft deep, weighing several thousand pounds after many years of adding sticks and material.

These nests are often described as looking like a giant bowl or “wine glass without the stem” made of sticks high in a big tree or on a cliff near water.

A nest you could almost sit in

Because eagles reuse and keep adding to the same nest every year, the structure slowly turns into a massive wooden platform. Think of a small hot tub or a kiddie pool made of sticks:

Wide enough that an adult person standing inside a display nest looks dwarfed by it.

Deep enough that multiple eaglets with 6‑foot wingspans can move around before they learn to fly.

One famous example in Florida reached about 10 feet in diameter and roughly 20 feet tall, and another long‑used nest in Ohio weighed over 2 tons before the tree finally came down.

Why they get so big

Eagles are long‑lived and loyal to their nesting territory. A pair often returns to the same site year after year and:

Adds new sticks, branches, and grass every season, slowly thickening the base.

Repairs damage from storms and snow, reinforcing weak spots instead of starting over.

Builds near water, so the nest must be sturdy enough to handle wind and weather while raising chicks.

Over a decade or more, that “starter home” becomes a huge, layered structure that can literally reshape the tree supporting it.

Mini forum-style note

“If you ever see an eagle’s nest in person, don’t be surprised if it looks more like a piece of outdoor furniture than a typical bird nest—it’s easily the size of a small couch or bathtub up in a tree.”

TL;DR: An eagle’s nest is usually about 5–6 feet wide and a few feet deep, but old nests can reach roughly 10 feet across, over 20 feet deep, and weigh several thousand pounds after years of reuse.
