Diurnal behavior of Blue-eared Pheasant ( Crossoptilon auritum) was studied by scan sampling in Zecha forest,Gansu from 1^st December,2007 to 10th January,2008. Feeding proportion of Blue-eared Pheasant was highest ( 40. 62% ) during day time, follow by resting ( 28. 01% ), moving ( 19. 17% ), guarding (12. 55% ). The percentage of moving pheasant in different habitats was significant difference (χ² = 13. 994, df = 3,P < 0. 01),as well as resting percentage(χ² = 15. 899,df = 3,P < 0. 01). Foraging behavior of Blue- eared Pheasant peaked at 9:00 - 11:00 and 15:00 - 17:00 and moving behavior concentrated at 9:00 - 10:00 and 18:00 - 19:00. The resting behavior commonly appeared at 11:00 - 13:00. Pheasants spend more time to forage and guard in farmland habitat than they were in other habitats,and they rested more in stream belt and shrub forest.
