🦅 Bald Eagle Overview

• Scientific name: Haliaeetus leucocephalus

• Family: Accipitridae (hawks, kites, and eagles)

• Range: North America only

• Status: Least Concern (a major conservation success story)

• National symbol of the United States since 1782

Despite the name, bald eagles are not actually bald—the word “bald” comes from an old English term meaning white‑headed.

🍽️ Diet & Hunting Behavior

Primary Diet

• Fish (their main food source)

• Waterfowl (ducks, geese)

• Small mammals (rabbits, muskrats)

• Reptiles and amphibians

• Carrion (roadkill, dead fish)

Hunting Style

• Eagles typically snatch fish from the water’s surface using powerful talons.

• They rely on keen eyesight—up to 4–5 times sharper than humans.

• Opportunistic feeders: they often steal food from other birds, especially ospreys (a behavior called kleptoparasitism).

💕 Mating & Pair Bonds

Pairing

• Bald eagles mate for life.

• If one mate dies, the surviving eagle will usually find a new partner.

Courtship Displays

• Dramatic aerial acrobatics

• Cartwheel dives where mates lock talons mid‑air

• Loud calling and synchronized flight

Breeding Season

• Varies by latitude:

    • Southern U.S.: fall to early winter

    • Northern U.S./Canada: late winter to early spring

🪹 Nesting & Eggs

Nests

• Built near large bodies of water

• Usually in tall trees or cliffs

• Constructed of sticks and lined with soft materials

• Among the largest bird nests in the world

    • Typical: 6–8 feet wide

    • Record nest: 20 feet deep, weighing over 2 tons

Eggs & Chicks

• 1–3 eggs per clutch (usually 2)

• Incubation: ~35 days

• Both parents incubate and feed chicks

• Chicks fledge (leave nest) at 10–12 weeks

---

🕊️ Lifespan

• Wild: 20–30 years

• Captivity: Up to 40–50 years

The oldest confirmed wild bald eagle lived at least 38 years.

🧭 Migration & Territory

Migration

• Bald eagles are partial migrants.

• Northern populations often migrate south in winter when water freezes.

• Southern eagles may remain year‑round.

Territory

• Highly territorial during nesting season

• Non‑breeding eagles often gather in large communal roosts, especially in winter

---

📏 Size & Physical Features

• Wingspan: 6–7.5 feet

• Weight:

    • Males: 6–10 lbs

    • Females: 10–14 lbs (females are noticeably larger)

• Adult plumage:

    • White head and tail

    • Dark brown body and wings

• Juveniles:

    • Mostly dark with mottled white

    • Don’t get full adult coloration until 4–5 years old

🎶 Calls & Communication

• Contrary to movies, bald eagles do not have a powerful, majestic call.

• Their real vocalization is a high‑pitched chirping or squealing.

• The iconic “eagle scream” used in films usually belongs to a red‑tailed hawk.

🌿 Conservation Success Story

Past Decline

• Nearly wiped out by:

    • DDT pesticide (caused eggshell thinning)

    • Habitat destruction

    • Hunting and poisoning

Recovery

• DDT banned in 1972

• Protected under:

    • Bald and Golden Eagle Protection Act

    • Endangered Species Act (removed in 2007)

• Populations rebounded dramatically

Today, bald eagles are commonly seen again across much of the U.S., including the Midwest.

🤯 Fun & Fascinating Facts

• Bald eagles can fly over 10,000 feet high

• They can spot prey over a mile away

• Their grip strength can exceed 400 psi

• They don’t reach breeding maturity until 4–5 years old

• Benjamin Franklin famously did not want the bald eagle as the national bird—he preferred the turkey

📸 Bald Eagles & Photography Tip (Your World)

If you’re photographing bald eagles:

• Winter is prime time (leaf‑off trees + ice fishing behavior)

• Look near rivers, lakes, and dams

• Early morning light highlights white head contrast beautifully

• Juveniles offer dramatic, less predictable plumage patterns
