Q 01Which of these is the largest living bird by mass and height?
Ostrich
The ostrich is the largest living bird: an adult male stands about 2.7 m and can weigh over 150 kg, yet its egg is the smallest of any bird relative to the adult.
Q 02Chicks of which Amazon bird hatch with claws on their wings for clambering through branches?
Hoatzin
Hoatzin chicks hatch with two claws on each wing; if threatened they drop into the water beneath the nest, then use the claws to climb back up. The claws disappear as the birds mature.
Q 03Which bird species possesses the largest wingspan among all living birds, reaching up to 3.7 metres?
Wandering Albatross
The Wandering Albatross's wingspan can reach 3.7 m (12 ft), letting it glide for hours over the Southern Ocean with barely a wingbeat.
Q 04Besides aiding in feeding, what is a primary function of a toucan's large, colorful beak?
Releasing excess heat
Releasing excess heat: a toco toucan's bill is laced with blood vessels it can open or close, shedding up to a large share of body heat, a function demonstrated by thermal imaging in 2009.
Q 05What do most vultures primarily consume as their main food source?
Carrion
Carrion: vultures are scavengers that feed on dead animals, and by stripping carcasses quickly with highly acidic stomachs they limit the spread of disease to other wildlife.
Q 06Which bird is often cited as having intelligence comparable to primates, with problem-solving and tool use?
Raven
Young ravens perform about as well as adult chimpanzees and orangutans on tests of causal reasoning and social learning.
Q 07The largest egg laid by any living bird weighs about as much as how many chicken eggs?
24
About 24: an ostrich egg weighs around 1.4 kg, roughly the mass of two dozen 60 g chicken eggs, yet relative to the mother it is the smallest egg of any bird.
Q 08Which large flightless bird of New Guinea and northeastern Australia has a helmet-like casque?
Cassowary
The cassowary's casque is a helmet-like crest of spongy bone under a horny sheath; the bird's dagger-like inner toe claw, up to 12 cm long, is why it is often called the world's most dangerous bird.
Q 09The pink colour of flamingos comes from which pigments in their diet?
Carotenoids
Carotenoids from the algae and brine shrimp flamingos eat are deposited in feathers and skin; captive birds fed too little carotenoid fade to pale pink even when otherwise well nourished.
Q 10How many neck vertebrae does an owl have, compared with seven in humans?
14
Owls have 14 neck vertebrae, twice the human seven, and extra-wide openings for the vertebral arteries keep blood flowing to the brain while the head swivels.
Q 11Males of which bird family build and decorate elaborate stick structures purely to impress mates, never to nest in?
Bowerbird
Bowerbird males decorate their bowers with sticks and brightly coloured objects; the structure is a stage, not a nest.
Q 12What is the primary material that makes up a bird's feathers?
Keratin
Feathers, unique to birds, are primarily composed of keratin, a lightweight and durable protein also found in human hair and nails.
Q 13Which bird holds the record for the longest known non-stop migratory flight?
Bar-tailed Godwit

Q 22Which bird breaks open large eggs by tossing pebbles onto them?
Egyptian vulture
The Egyptian vulture hurls stones at ostrich eggs too big to lift, one of the few documented cases of tool use in birds; it also uses twigs to gather wool for lining its nest.
Q 23Which of these is a typical characteristic of birds of prey?
Sharp talons and hooked beaks
Sharp talons and hooked beaks: birds of prey seize prey with their feet and tear it with the hooked bill, while keen eyesight lets them spot a target from far off or in flight.

Q 24The only penguin species living at, and just above, the equator is native to which island group?
Galápagos Islands
The Galápagos Islands host the only penguin found at the equator, because the cold, nutrient-rich Humboldt and Cromwell currents keep the surrounding water cool enough for a bird otherwise tied to the southern oceans.
Q 25What is a significant part of a Blue Jay's diet, especially during autumn?
Acorns
Blue jays hide many of the acorns they gather to eat later, and forgotten caches help oaks spread.
