• Scientific name: Haliaeetus leucocephalus
• Family: Accipitridae (hawks, kites, and eagles)
• Range: North America only
• Status: Least Concern (a major conservation success story)

🍽️ 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.

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
