Goosebumps and shivering are physiological responses that help regulate body temperature in cold conditions. Goosebumps occur when tiny muscles at the base of hair follicles contract, causing hair to stand upright, which creates an insulating layer of air. Shivering involves rapid muscle contractions that generate heat, increasing body temperature. Together, these responses help maintain warmth by minimizing heat loss and producing additional heat.

Goosebumps help keep you warm by causing your hairs to stand up, creating a layer of insulation that traps heat close to your body.
The arrector pilli does not cause shivering - it's responsible for "goosebumps".. shivering is caused by skeletal-muscles..
Shivering is an involuntary muscular response from the body, triggered by cold. The "shivering" muscles are trying to internally generate heat, to help keep you warm.
Keep warm, and try not to become frightened.
People get goosebumps when they're cold, or thrilled. Goosebumps are caused by tiny muscles, controlled by nerves to keep you warm.
Not very effectively. Shivering is a last-ditch attempt by the body to generate heat in it's own muscles to try and ward off increasing cold, but the operative words are "last ditch" - it just doesn't help much if one is really chilled.
Stay Warm
Shivering to produce heat, goosebumps, blood capillaries narrowing.
If it is a wild bird, it may be shivering due to too much stimulation. Call and find someone experienced in fostering young animals.
Shivering warms the body by increasing metabolism.
Yes, infact it does. When you shiver, your body recoginzes that you are cold and conserves heat to keep you warm.
