50 free Bald Eagle trivia questions with answers — nature quiz, new questions added Aug 2026.
The bald eagle is the national bird of the United States, and this quiz covers the animal behind the emblem. It explains why a bird with a full head of feathers is called 'bald', why females are a quarter bigger than males, how it snatches fish with spiny toes and a grip ten times a human's, why it steals from ospreys, and how it builds the biggest tree nest of any animal, including a Florida monster that weighed three tons. It also follows the eagle's rise, fall and comeback: the Great Seal of 1782, Benjamin Franklin's letter calling it a bird of bad moral character (and the myth that he wanted the turkey), the 70,000 shot in Alaska, the 1940 protection act, the DDT crash to 412 nesting pairs, delisting in 2007, and the 2024 act of Congress that finally made 'national bird' official. There are questions on eagle feathers in Native American traditions, the National Eagle Repository, and why Hollywood dubs in a red-tailed hawk's scream. Easy questions ask what it eats and what colour its head is; hard ones want dive speeds, wing chords and Bergmann's rule. Every answer was checked against Wikipedia's article on the bald eagle, and each question carries the sentence that supports it. Our Birds and Peregrine Falcon quizzes go wider.

Q 01Why is the bald eagle called 'bald'?
From an old meaning of the word: white-headed
The species name leucocephalus says the same thing in Greek: 'white head'.
Q 02The bald eagle belongs to which genus?
Haliaeetus, the sea eagles
The genus name is Greek for 'sea eagle'; its Old World counterpart has a tan head instead of a white one.
Q 03What does the bald eagle mainly eat?
Fish
Across 20 diet studies fish made up 56%, birds 28% and mammals 14%; more than 400 prey species are on the list.
Q 04Which sex of bald eagle is larger?
Females
Plumage is identical, so size is the only clue; the biggest Alaskan hens top 7 kg with a 2.4-metre wingspan.
Q 05The bald eagle builds the largest tree nest of any animal; one Florida nest weighed how much?
About 3 tons
It was 6.1 metres deep and 2.9 across; nests are reused and topped up every year until the branches give way.
Q 06At what age does a bald eagle reach sexual maturity and full white-headed plumage?
Four to five years
Until then it is streaky brown and easily confused with a golden eagle.
Q 07The bald eagle was removed from the US endangered and threatened species list in which year?
2007
It had gone from 'endangered' to 'threatened' in 1995 after DDT was banned and hunting outlawed.
Q 08Under what name did Linnaeus originally describe the bald eagle?
Falco leucocephalus
Eighteenth-century taxonomy lumped most raptors into Falco; the sea-eagle genus came later.
Q 09Which Eurasian bird forms a 'species pair' with the bald eagle, filling the same niche across the ocean?
Haliaeetus albicilla, the white-tailed
One is white-headed, the other tan-headed, and they split from other sea eagles at least 10 million years ago.
Q 10How many subspecies of bald eagle are recognised?
Two
The northern one is larger, which may simply be Bergmann's rule at work: bigger bodies further from the equator.
Q 11Which is the only raptor-like bird in North America larger than the bald eagle?
The California condor
The golden eagle is only about 455 g lighter on average and actually has a longer wing chord.
Q 12A typical bald eagle wingspan is roughly what?
1.8 to 2.3 m
Body length runs 70 to 102 cm and weight 3 to 6.3 kg; a New York bird shot in 1876 supposedly weighed 8.2 kg.
Q 13Where do the largest bald eagles live?
Alaska
Bergmann's rule again: South Carolina birds average 3.27 kg, while some Alaskan hens pass 7 kg.
Q 21A bald eagle's grip is estimated to be how much stronger than a human's?
Ten times
The big hind talon pierces vital organs while the front toes hold the prey still.
Q 22The habit of stealing prey from other predators, common in bald eagles, is called what?
Kleptoparasitism
Ospreys are frequent victims; the eagle also happily scavenges carcasses up to the size of whales.
Q 23What happens if a bald eagle grabs a fish too heavy to lift?
It may be dragged into the water
Eagles can swim, and often paddle or drag big salmon ashore with their talons before eating.
Q 14How is the bald eagle's actual call best described?
Weak, staccato chirping whistles
It sounds a bit like a gull; the ferocious scream you hear on television usually belongs to a hawk.
Q 15Which bird's call is usually dubbed over the bald eagle's in films and TV?
Red-tailed hawk
The hawk's cry is far louder and more powerful than the eagle's real chirping whistle.
Q 16Bald eagles were found nesting for the first time in which Canadian city in March 2024?
Toronto
By 2018 the species was nesting in every continental US state and Canadian province.
Q 17At its low point in the 1950s, how many nesting pairs remained in the 48 contiguous states?
412
The early 18th-century population had been 300,000 to 500,000; by 2006 the states reported nearly 9,800 pairs.
Q 18As of 2007, which contiguous state had the most breeding pairs of bald eagles?
Minnesota
Its estimated 1,312 pairs edged out Florida's 1,166.
Q 19What is the bald eagle's dive speed?
120 to 160 km/h
It rarely dives vertically; cruising speed is 56 to 70 km/h, dropping to about 48 km/h with a fish in its talons.
Q 20Structures on a bald eagle's toes that help it grip slippery fish are called what?
Spicules
Its grip is estimated at ten times the strength of a human hand.
Q 24Bald eagles can store food in a throat pouch called what?
A crop
It can hold about a kilogram, useful when a carcass turns up and the next meal is uncertain.
Q 25Bald eagle courtship includes 'cartwheels', in which the pair do what?
Lock talons and free-fall
They separate just before hitting the ground; pairs generally stay together for life.
Q 26How many eggs does a bald eagle typically lay?
Two
One to three is the normal range; nearly half of pairs manage to raise two fledglings, unusually good for a large eagle.
Q 27Compared with most raptors, bald eagles breed when?
Early, laying by late February
Nest-building starts by mid-February and eggs may be laid in deep snow in the north.
Q 28A young eaglet can gain up to how much weight a day, the fastest growth of any North American bird?
170 g
By eight weeks the chicks can lift off the nest platform; they fledge at 8 to 14 weeks.
Q 29Bald eagles have been recorded nesting on the ground on which treeless Alaskan island?
Amchitka
In Sonora, Mexico, they have even nested on top of hecho cactuses.
Q 30What is the average lifespan of a wild bald eagle?
About 20 years
The oldest confirmed wild bird reached 38.
