In Korea cold wave starts end of September and suddenly becomes severe in mid October. The coldest period is from mid. January to mid. February, and windy season follows and the Spring gradually returns. The Pheasants spend the incubation period in low hills and cultivated plains but the Summer is spent in the adjucent territory where protein food and water are easily obtained. In September gras is cut and by early November the rice harvest is completed. They make local movement accordingly. From October the Pheasants do much damage to young wheat. In the Autumn they live chiefly in cultivation and eat locusts and other such food. From mid December they move into hillsides for more food and warmth. The female completes moult at end of November but some young delays till end of December or even later. In December the cock which moult early ascend hills while female and young still remain in the plain. Therefore two sexes flock separately: females are chiefly found in deciduous forest while males in mixed forest of deciduous and coniferous trees. The cock starts crowing in early March to pair and do much damage to bean fields. After the sunrise to 8 or 9 a. m. and from 4 p. m. to sunset are the best feeding hours.
