Flashcards for Avian Biology Exam Review

CNS

Central Nervous System

Motor vs. Sensory Signals

Signals that carry information from the brain to muscles/glands (motor) vs. signals that carry information from sensory receptors to the brain (sensory).

Cerebellum (birds)

Balance and coordination.

Cerebrum (birds)

Higher-level thinking, learning, and problem-solving.

Olfactory Lobe (birds)

Processing smells.

Optic Lobe (birds)

Processing visual information.

Brainstem (Medulla Oblongata) (birds)

Basic life functions like breathing and heart rate.

Birds with relatively large brains

Some groups like parrots and corvids.

Birds with relatively large forebrains

Birds with relatively large forebrains exhibit learned or innovative behaviors.

Tidbitting

A behavior where a rooster offers food to a hen, often accompanied by specific calls and head movements.

Rooster's wattle

A structure on a rooster used in social signaling.

Gaze Stabilization

Helps maintain a stable visual field during head movements.

Overlapping Visual Fields

Allows for depth perception.

Retina

Detects light and converts it into signals the brain can interpret.

Lens

Focuses light onto the retina.

Iris

Controls the amount of light entering the eye.

Nictitating Membrane

A transparent membrane that protects and moistens the eye.
