Bird Basics, Feathers & Flight

Q: What class of animals includes modern birds?
A: Aves.

Q: What body covering is unique to birds among living animals?
A: Feathers.

Q: What are feathers made largely from?
A: Keratin, a structural protein also found in hair and nails.

Q: What is molting?
A: The process of shedding and replacing feathers.

Q: What is preening?
A: Using the beak to clean, arrange, and maintain feathers.

Q: What gland supplies oil used by many birds during preening?
A: The uropygial, or preen, gland.

Q: Do all birds fly?

A: Hummingbirds.

Q: Why are many bird bones described as pneumatic?
A: Some contain air spaces connected with the respiratory system, reducing weight while maintaining structure.

Q: Are all bird bones hollow?
A: No. Bird skeletons include solid and marrow-containing bones as well as pneumatic ones.

Q: What large chest bone anchors major flight muscles in many flying birds?
A: The keeled sternum.

Q: What is a bird's beak also called?

A: An expanded part of the esophagus used by many birds to temporarily store food.

Q: What is a cloaca?
A: A shared opening for digestive, urinary, and reproductive systems in most birds.

Q: Are birds warm-blooded?
A: Yes. They maintain high internal body temperatures through metabolism.

Q: What makes bird respiration especially efficient?
A: Lungs work with air sacs to maintain largely one-way airflow through gas-exchange structures.

Q: Why do flying birds need high metabolic rates?
A: Powered flight requires large amounts of energy and oxygen.

Q: What are primary feathers mainly important for?
A: Producing thrust and controlling flight near the wing tips.

Q: What are tail feathers used for in flight?
A: Steering, braking, balance, and display.

Q: What is soaring?
A: Staying aloft with little flapping by using rising air or favorable winds.

Q: What is a thermal?
A: A rising column of warm air that soaring birds can use to gain altitude.

A: Yes. The two sides of the syrinx can be controlled with remarkable independence.

Q: What is mimicry in birdsong?
A: Copying sounds made by other birds, animals, people, or the environment.

Q: What Australian bird is famous for extraordinary sound mimicry?
A: The superb lyrebird.

Q: Why do woodpeckers drum on trees or other surfaces?
A: Drumming communicates territory and courtship, while pecking can also find food or excavate cavities.
