Dead air space (motionless air) is the best natural insulator. By puffing their fethers, they trap more air which helps them keep warmer.

They eat possibly large insects and small vertebrates
Sick or elderly birds may, but healthy birds can survive tough winters.

Male Pheasants puff up as a display during courtship while a female pheasant may puff up during the eggs incubation period when it does not lay any eggs but sits on a hatch of eggs. This is a natural phenomenon in all fowls and most birds.

Birds that move as the season changes. If a bird primarily eat insects it'd starve if it stayed somewhere where winters get cold.

A pheasant will puff up (as will most birds) when it gets cold. When a pheasant puffs up, it traps air between it's feathers and body, which acts as insulation to keep the bird warm. It may also be an indication the bird is not feeling well. When birds get sick, they feel like they are cold, even if the weather is warm.
By puffing out their feathers in the cold birds create a larger insulating layer of air and feathers, which helps them retain body heat. Many mammals do the same with their fur.
